I just bought a lenovo laptop, which came with preinstalled Windows 8.
When I turn it on the first thing I see is:
EFI network 0 for IPv4 (20-89-84-23-c3-45) boot failed
Checking media (Fail)
EFI network 0 for IPv6 (20-89-84-23-c3-45) boot failed
And then a blue screen:
Default Boot Device Missing or boot failed
Insert recovery media and hit any key
Then select boot manager to choose a new boot device or to boot recovery media
I am having a problem with a new Dell Inspiron 15 3520 that came with Windows 8 installed and that I had been using for only a month when it went bad.
The problems started when I turned it off about ten days ago, and went I turned it back on a couple days later, and it was stuck in the apparently famous Windows 8 "Automatic repair couldn't repair your pc"/BSOD loop. I was not able to boot into safe mode. System restores made no difference. Somewhere along the line I found something that said that I had an "inaccessible_boot_device error".
From the repair menu maze, I was able to get to a command prompt. I used this to copy almost all of my files off of computer.
Chkdsk showed no bad sectors, no bad partition records, or other irregularities. sfc returned "Windows Resource Protection did not find any integrity violations". Some test (I do not remember which) showed that the boot record and BCD were fine. The Dell hardware diagnostic test showed everything working fine.
I am thinking that it is possible that the source of this was a virus or mechanical problem (I saw no evidence for either). If I had to guess, however, I would imagine that the computer stopped working after an automatic update pushed a corrupted/incompatible driver. I have seen discussions online about people having problems with NVIDIA video and/or SATA AHCI Controller drivers, and Windows 8 getting corrupted and stuck in the BSOD loop from that. At some point I saw a Windows Update Log (I am not sure where), that showed that, as Windows shut down the last time it was functional, automatic updates installed a new AHCI driver.
I tried downloading some new drivers for the 3520 from the Dell web site and installing them on the dead computer through a thumb drive and the command prompt. The downloads are all executables, however, and when I tried to run them, I get the message, "the subsystem needed to support the image type is not present". I believe that this message means that the driver executables are 32bit apps and won't run from a 64 bit command prompt. I also tried to use the "Drivers and Utilities" disk that came with my PC to do some driver rollbacks, but, I can't understand the file names or folder structure on the disk, and, when I try some to run some of the exe files ("setup.exe", for example) to get a gui interface, I get the "the subsystem needed to support the image type is not present" message.
After working on the problem for a while, I borrowed a friend's Windows 8 installation disk set. The computer will boot to the repair options off of the 64bit disk, but not the 32bit one. I did attempt a System Refresh off of the 64bit disk, and got back the message, "The drive where Windows in installed is locked. Unlock the drive and try again."
Around the time that I was messing with the BIOS settings to get the computer to boot off of the Windows 8 disk, I started getting a message "Your PC needs to be repaired - Boot Configuration Data file is missing some required information -- File:BCD -- error code 0xc0000034" at the start of my boot ups. I am not sure if I deleted a file somewhere during my repair efforts, or if I am getting this message because the computer is confused in efforts trying to boot off of the DVD. I get this message even with the DVD removed and the BIOS set to boot off of the Windows Boot Manager, however, so I am guessing that a file is now missing. And the message stops me from getting into the repair menus/command prompt any other way except through the installation disk.
Earlier, about an hour ago, I left to go job searching, and left my computer in hibernate mode so I could bring it back up as soon as I got back. When I tapped keys on the keyboard, the computer powered up as usual, but it brought up the BSoD, stating it was missing files.
Prior to receiving this error, everything was working fine. I even set it to hibernate mode during the night, and it powered on this morning without any problems. I dunno if it's the multimedia keyboard I'm using or what that caused it.
I don't have an installation disc (since I bought it from Fry's Electronics about a year ago with 8 pre-installed), and neither do I have a recovery disc (since I didn't know how to make one.
Computer info: Windows 8 x64
Manufacturer: ASUS
how to fix the missing boot files, and how to do it without causing any data loss from either of my hard drives.
Last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
Does Windows 8.1 having driver WHQL problems?
I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.
I have a 'HP Envy m6-1158ca Notebook PC' running Windows 8 Pro and everything was good until I upgraded to Windows 8.1 Pro.
Immediately after that, it failed to recognize my second monitor (HP Pavilion 23fi 23-inch Diagonal IPS LED Backlit Monitor). I restarted several times assuming OS should recognize that. Device Manager did not show any driver for that new monitor.
Did a hardware troubleshooting and it found some errors. I rebooted the PC and now NOTHING SHOWS UP IN THE SCREEN. JUST A BLANK SCREEN!
After spending hours, I could not do anything. Finally with the support of HP customer service, I was able to access HP recovery mode (F11) and went back to default OS (Windows 8). Lost my data (was not able to backup a lot) and now having all other issues! By the way, F8 or Shift+F8 did not boot in safe mode.
Now every time I restart, it takes forever and randomly removes different drivers (audio etc.)! I now have two OS (Windows 8 and a recovery OS) and don't know how to remove that!
My question is what could happen when I upgraded to Windows 8.1 Pro? Everything was great before that upgrade.
Bought a new HP Windows 8 machine w/1tb hd. Finally broke secure boot. Partitioned drive so C drive would fit in my SSD, eventually cloned C partition to SSD. I can get it to boot the SSD if I (esc) at boot to specify 1-time boot to sata0 (SSD). If I boot non-stop, boots to sata1 spinning hd (where I got the SSD image from).
Talked to HP, they won't suppot, as original hd is fine. They eventually told me I need to look into BCDEDIT. Here is a screen shot with both drives connected:
Looking for best bcdedit command to boot from sata0, as default drive, (instead of sata1) which is my SSD.
Acer Aspire V5 is the PC I am using. I turn it on, the boot fails and the pc restarts. Then begins an automatic repair, which crashes and the PC turns off. It is a loop I cannot get out of. I don't have a Windows 8 Disc or anything like that.
View 2 Replies View RelatedI have a Lenovo G580 laptop 2gb RAM, i5, and 500gb HDD. It had windows 8 RTM 32 bit installed on its C drive. It had come with DOS preinstalled so I had to do a fresh install of windows 8 via bootable usb. It worked well for few months but now it refuses to boot and goes into "automatic recovery mode" and then it says that your pc needs to be repaired with a recovery disc.
I did not made any recovery disc when it was working so I tried to do a fresh install of win 8 and then win 7 via bootable usb, but both have failed. The screen freezes after blue logo of windows appears and then it restarts saying it has encountered an error and needs to be restarted.
I have tried booting it in safe mode along with all other options on start-up menu but it doesn't work.
My computer rebooted and then started coming up with the message: 'Reboot and select proper Boot device'
Now from what I understand this means that the computer is unable to detect a boot-able OS. I am silly and haven't yet created a windows recovery disk or flash drive.
However my question is, is there a way I can get a recovery utility of some kind off the net so that I can get the computer to detect the boot-able OS ?
Firstly I created a partition of 1 GB on my 128GB OCZ Agility 3
Then I used bitlocker to encrypt it, and then for some reason when I tried to reboot the computer after doing the aforementioned, I get the message that windows cant boot, because the boot configuration is missing or conatins errors
I dont see how BitLocker and Disk Management can screw something up so much so that they either deleted or encrypted my boot config rendering me unable to boot up the computer.
What I did was shrinking the c:drive by 1000mb then formatted and partitioned those 1000 mb into a new drive. Secondly I encrypted the 1gig with Bitlocker with a short 12-character password.
I am now unable to boot up my laptop.
I have an HP Pavilion TouchSmart with windows 8. Model number 14-b109wm. Yesterday my laptop was working perfectly. This morning when I tried to turn it on I got a message saying, "Boot device not found. Please install an operating system on your hard disk." I clicked F2 for system diagnostics and ran two tests for the hard drive. The "quick test" said "passed." So I ran the "extensive" test and it said "not installed." I dont know what any of this means or how to fix it. I called HP and the lady barely spoke english. She said the hard drive needs to be re-seated. Again, dont know what that means. The F8 and F12 keys dont work either.

Yesterday I shut down the computer normally, but when I try to restarted, after Dell logo appeared, on a black screen appeared the message: "Check media..". After a few seconds, on a black screen a new message was shown: "No boot device found. Press any key to reboot the machine".
I've looked on the internet and I saw it's a common error and everybody solved it with "Windows Boot Manager" as a first choice in UEFI Boot List Option. My problem is that I don't have this option. I have only two options:
1. UEFI Onboard LAN IPv4
2. UEFI Onboard LAN IPv6
I press F9 to setup the defaults, I changed to Legacy mode, but no results.
My BIOS Version is AO( or 0 )7
My brother brought his PC to me with the above error.
The rest of it is File: BCD and error code 0xc0000034. And of course being my brother he did not make a recovery CD. There is also no windows twenty five digit serial number sticker on the case.
I bought a new laptop 350gb HDD with Windows 8 64bit preinstalled (no disc came with it) however I needed win7 32bit for my job since the softwares used are only compatible with old win version. I managed to back up my Windows 8 before I partitioned my HDD into 3 drives and installed win7 ultimate 32 bit on a different partition. I remember that my Windows 8 was installed in Drive C (100GB) while I have 80+GB for Shared files on Drive E and the rest of the memory are for Drive D where I installed win 7 and I labeled each drives accordingly. At first everything was working fine on both O.S, it was giving me the dual boot option at start up but I forgot if I really have tested running both O.S. before I gave my laptop to my supervisor and asked him a favor to intall the softwares for work purposes.
My supervisor then approached me and said that there might be some incompatibility issue with the updates I have on my win7 coz some applications don't install so he asked me if its ok if he reinstalls a new win7 so I said yes since Im confident that its will work fine and I have backed up my Windows 8 anyway, in short, I left everything into his hands. Later, he then got back to me and told me every job related softwares now work except that my Windows 8 now doesnt show and yes, dual boot option is not there anymore and it boots automatically to win7 like Windows 8 is not there.
I've read some forums how to check if your O.S are still there and it could just be a boot up issue and use of Easy BCD might work. I have attached images below for your reference. Now what I'm confused of is that my Windows 8 appears to be in Drive D and win7 could be in Drive C, which I'm thinking if they were exchanged when my sup reinstalled win7 or he may have overlapped my Windows 8. Im pretty sure he knows which drive is for which O.S since I labeled them. Now Im afraid to use EasyBCD on the wrong drive and I cant approach my supervisor anymore to bother him again since he worked on my laptop for almost the whole day at work.
- if both o.s. are still intact and recognized
- why the Drive letters got mixed up and how to check which drive has which o.s coz it seems like both drives has a part of my work related applications (didn't put personal files yet on win 8 when I had both o.s installed)
- is Drive D really is my Windows 8 now?
- does Easy BCD really work
- how to use Easy BCD to get my Windows 8 to boot up to or both of them to show at start up without corrupting my work related softwares

My daughters Windows 8 laptop is now displaying "The Boot Configuration Data for your PC is missing or contain errors".
File:BootBCD
Error code: 0xc00000001
I can get access onto F2 but that's all.
Last night I set Acronis Disk Director to merge two partitions on my C drive. I had an unnallocated 100mb that used to be partitioned as system reserved, but I deleted that partition as it was not needed. So I made a new partition out of that unallocated space and set it to merge with my primary partition on my c drive. It restarted my computer and 40% through, showed an error and restarted quickly. Now I get the following message when attempting to boot my computer:
File: BootBCD
Status: 0xc0000225
Info: The Boot Configuration Data for your PC is missing or contains errors.
The second partition, that I attempted to merge, now has 1mb of space on it. Whenever I try to run chkdsk on the primary partition, it says that the disk structure is corrupt and unreadable. I need my c drive recovered.
I have looked around a bit and all solutions to this problem require me to get into the startup screen when booting from the installation disk upon startup. The problem is I cannot get to that screen!!
I am a uni student and can download windows 8 OS for free at msdnaa, I have done that and made an image file on a dvd and usb stick. I then put both of those into my dell N5010 (which is running win 7 now) and try to access them upon startup, (I go into the boot menu and try booting from booth DVD and USB) and both times I just get the error "boot manager is missing press ctr, alt, del to restart) so I cannot even get into the installation screen to do the repair that is says I need to do on all the other solutions I have seen.
Have a Gateway Desktop. Upgraded from 8 to 8.1.
Somehow I disabled the disabled Password Logon and its back asking for a password at boot.
Owner doesn't remember original password when setup.
I have a password blanking cd that I've used on both 8 and 8.1 pc's.
The problem is I can't boot from the CD and I can't, obviously, use that wonderful new setting, "Update", "Update and Recovery" and the option to boot with USB, CD etc. since I can't access the OS.
I have the BIOS set for the CD/DVD drive for first boot however boot options only show the "UEFI: ST....." drive.So I can't boot from within or without.
I've got a windows 8 laptop which gives me this error message when i try to switch it on:
"Your PC needs to be repaired The boot configuration data file is missing some required information.
File:BCD Error Code : 0xc000000d ............................" I'm sure you are all familiar with the rest of this dreaded error code.
I've tried all the repair options, recovery disks to a windows 8 bootable flash disk, the command prompt fix boot commands as well but still I get the same error message whenever i try to boot windows.
Now I'd like to know, can't i just copy the boot folders from another similar windows 8 pc and paste them into my harddrive to fix this?
I have a dual boot system Windows 7 & Windows 8.1. When I start my PC I get the DOS black and white 'Choose An Operating System'. But when I am in Windows 8.1 and restart, I get the Windows 8.1 (blue flag etc) 'Choose An Operating System'. What I want is to get the Windows 8.1 version all the time.Is this possible?
View 8 Replies View RelatedI wanted to do a fresh windows 8.1 install (i have a samsung NP500P4C-T03CL notebook with windows 8 OEM preinstalled and when i updated to 8.1 the system went slow and "faily"). So i put the CD on the drive, but for my suprise when i reboted the system to enter the BIOS the F2 key didn't do the job, nor it appeared on the splash screen on samsung. After googling a lot and under trial/error concept i could enter the BIOS via Shift+Restart.
I did some changes to the BIOS booting set-up and noticed i have 2 Windows Boot Manager, the CD, the HDD and one option called "SETUP" that has a "!" ("!3.Setup"). So i tried every combination posible with Secure boot unabled, and UEFI+CSM OS, also with UEFI disabled, and none gave me the option to enter bios with F2, or recovery with F4. I managed to install win7 on another HDD. Main thing, besides the F2, F4, F8, F9, F12 (yes i prove all of them, even ESC), is that whenever i change the boot order it's not saved, and it is restablished to:
1. Windows Boot Manager
2. Windows Boot Manager
3. Setup
4. HDD
5. CD
Also i noticed that on the password options the one for the HDD appears grayed and as "FROZEN". I entered user and supervisor password, neither cleared the HDD one. i want to keep the BIOS update as a last resort. clearly it's not hdd related as the same thing happened when i tried another hdd with win7).
I have a desktop PC Acer XC600, the hard disk is formatted in the UEFI-Scheme. Now I want to do a clean install of a fresh Windows 8, but I cannot manage to boot into UEFI-mode, neither from DVD or USB.
I can reach a boot menu by pressing F12, but there is nothing like shown in the article about installing Windows 8 in UEFI mode. Only standard bios devices show up. There are simply no UEFI devices. I tried different usb sticks, dvds, formatted them different ways, but the best I can get is the point where setup says "cannot install because the disk is formatted GPT".
But the acutal system is definitely running in UEFI mode (?)
I upgraded my Dell XPS10 from Windows RT 8 to Windows RT 8.1 Preview.
It has 2 serious issues:
1) Windows RT is not activated.
2) Device gets stuck at boot logo.
Now I'm trying to use a USB recovery drive to roll my XPS10 back to Windows RT 8. Unfortunately I failed to use the recovery files from Microsoft Surface RT, XPS10 could not boot with those files.
I have got the recovery page that loads up first

Unfortunatly I haven't made a backup or recovery file to boot my computer from so I'm stuck with the issue of finding a windows 8 iso file that matches my system, i tried getting the windows 8 iso from microsofts website but it asks for a product key before it lets you download the file, the problem is that my product key is built into the laptop and Toshiba has not provided me with the key on a sticker on the bottom or through any other method. apparently its built into the BIOS. i have a 16gb USB stick that i can boot from. using a key finder is obviously not an option because i cant start up the laptop. I was also wondering if i manage to find a windows 8 iso file to boot from, will my toshiba laptop automatically fill in the product key for windows 8 as i dont have it.
I have a PC that I have been running Win 8 Consumer Preview since it was available. I have two HD's partitioned to dual boot Windows XP SP3 and Win 8, with Win 8 set as default. I have been running Win 8 over 95% of the time. Everything has been working fine until this morning.
When I came out of screensaver in Win 8 and attempted to get to my login page nothing happened. So i shut down using the power button, after that Win 8 would not start, nor could I get to the dual boot screen. After a number of tries i finally got the dual boot screen and attempted to start in XP. XP nearly completely started (I had desktop, task bar, desktop icons, etc), but then it shut down as well and displayed a blue screen and error message "A problem has been detected and windows has been shut down to prevent damage to your computer.".
I have tried starting from my XP install disk with the same error message ("A problem has been detected and windows has been shut down to prevent damage to your computer." ). I have tried starting from USB flash drive that has my Win 8 Install. It is the same USB flash drive that i originally used to install Win 8. It hangs at the 'fish' screen. I have tried just starting the machine several times, but it hangs at 'Preparing Automatic Repair'.
I have everything disconnected (printers. ethernet, USB Wifi adaptor). The only things connected are my keyboard/mouse, speakers, and (1) 17" monitor. I normally run a 23" widescreen and the 17" monitor.
I have disconnected the slave HD and tried booting with XP install disk and USB Win 8 with no success.
Currently, both HD's are connected. I tried a normal start up and the machine is stuck at 'Preparing Automatic Repair'
This has never happened before such that I could not boot into either XP or the XP Install CD or the Win 8 USB Install flash drive, in order to attempt repairs to MBR or Win 8 troubleshooting diagnostics.
Complete error message on Blue screen:
"A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

I have a Dell 755 dual core, I loaded win 7 had a problem was with my CD rom, on boot up it was there, in devices it was there name and model, but as soon as I put CD in and opened the CD it would disappear off the machine sometime it would read what was on the disc and then disappear, I asked many question nobody gave me an answer. I installed it on a Dell 270 it works great.
Now on Win 8, the problem I have is if I have my mobile modem in the usb when I boot up my CD rom doesn't appear, if I take the modem out and boot up my CD rom is there with the drive letter G, when I put the modem in the CD remains and works correctly.
My (12-year-old) son's computer won't boot. It's a Dell Inspiron 17" running Windows 8, bought from Costco in July 2013. When I turn it on, Dell logo comes on and then in upper left it says "Checking Media [fail]", then "checking media" again, then "No Boot Device Found. Press any key to reboot the machine". I insert a USB recovery drive (it was made for my Toshiba that runs Windows 8.1, but it should work anyway, right?).
I choose US keyboard layout and it then opens into Recovery Environment. I choose Troubleshoot → Refresh Your PC. Message appears "The drive where Windows is installed is locked. Unlock the drive and try again." I go to Troubleshoot → Startup Repair, which runs and then says "Startup Repair couldn't repair your PC." I then go back to Troubleshoot → Command Prompt and run chkdsk on Windows drive (c). It says "Windows has checked the file system and found no problems." Dell would probably tell me it's a hard drive failure and tell me to buy another one.
While I was messing around with my laptop, I decided to add on a fourth operating system, Arch Linux. I suppose I was pushing my luck a bit . Anyways, during the installation, I accidentally deleted the EFI system partition from my laptop, which contained the Windows Boot Manager and necessary files to boot. Great. I only made things worse by trying to troubleshoot, and broke grub as well.
I have a Windows 8 repair disk I made using the Windows 8 built in utility, but it does not boot: the computer turns on, and just hangs at the Toshiba splash screen.
I also can obviously not access the Toshiba recovery partitions, as they are booted into just like Windows itself.
I found a bootx64.efi file on one of my system's recovery partitions (Toshiba seems to have some really complex system going on) and placed it in EFIootootx64.efi. According to this site, FGA: The EFI boot process., I need to place the bkpbootmgfw.efi (on my system, that was what it was called, but I suspect boot-repair (ubuntu tool) messed something up when I was first setting up grub and the ESP and the bkp stands for backup) back onto the EFI System Partition.
Where to look for in the various Windows Imaging Format .wim and .swm files I have laying around my recovery partition(s) in order to extract the necessary EFI files. Any Windows Repair iso that works.
