Setup Installation :: Multiboot Win XP / 7 / 8.1 Missing NTLDR
Dec 18, 2013
I had a working multiboot setup on my Acer Aspire One ZG5, running win xp, 7, 8.1, linux. I decided to add an extra partition, and in doing the resizing lost my Grub boot loader so can no longer boot into linux, but that's not important atm. I have also messed up my windows boot loader and at the moment I can only boot into win 8.1.
Win 8.1, 7 and legacy OS (xp) show in the boot menu but when I choose to boot into either xp or 7, I am presented with the message
windows failed to start
file: /ntldr
status 0xc0000225
Previously I had the message filesystem unknown , missing NTLDR, but I ran the recovery console and that message no longer appears.

I have (perhaps I should say had) a multi-boot system. Originally I installed my 6 Windows OS's and then installed my two favorite Linux distros. I like the ability to customize the Grub menu which Linux gives me. Unfortunately Grub did not detect all 6 of my Windows installations but one of the boot options it did detect took me back into my original Windows menu which showed all 6 of the Windows systems. So that's the setup which I have been using successfully for the past few months. (One boot menu which boots into another). Today my Windows boot menu has become unusable and probably corrupt.
At first I had the problem that I was only able to boot into Windows 8.1 (no windows menu at all). Then I used EasyBCD which I had inside Windows 8.1 At first EasyBCD indicated an inability to load any boot file at all. Subsequently after rebooting into 8.1 a few times more I tried it again. It then showed a boot menu but with only Windows 8.1 listed. I subsequently was able to use the add operating system function to add all the other Windows systems again. I then clicked save to save the new configuration. Now I do see all six Windows systems at boot but neither of them, even Windows 8.1 will boot. Where I should start to get back into one of these six Windows operating systems so that I can possible use the EasyBCD repair function to access the others. I think I had EasyBCD installed inside each Windows OS At the moment I am dependent on Linux alone for Internet access. I trust this is clear.
As nothing in Linux has changed, I assume I need to fix the problem from the Windows side of things. I do have that one option when I get into that blue Windows 8 style boot menu to "change options" I thought EasyBCD would have restored the Windows 7 style text boot menu but it did not. Other than that I have the various Windows installation disks and a Win7 repair disk as well as various full partition backups on an external hard drive. What do do about a corrupt bcd file without being inside Windows, and I don't know much about EasyBCD. Would a refresh/reset of Win 8.1 from the install disk be a good way to start? I did get the message of "files missing" when I tried to do a system recovery drive while inside Windows 8.1 today, so there are issues with that OS.

I have been using Windows 7 Pro (64) for several years, and today installed a newly purchased Windows 8 Pro (64) OS. I looked on-line and found many articles on how to multi-boot back to Windows 7 after installing Windows 8, and believe I have done this correctly (more below), but when booting up I do not ever see a multi-boot menu, my system boots directly into Windows 8.
When installing Win 8, I booted from my CD/DVD drive with the Win 8 OS media in the drive. (I had previously reduced the volume of my Windows 7 drive and created a new partition that I called "Windows8". ). At the appropriate time in the Win 8 install I chose "Custom", then chose the newly created "Windows 8" partition, then proceeded with the Win 8 OS install. As mentioned above, I do not see the multi-boot menu when booting up, however when in Windows 8 I can see the Windows 7 drive in "Computer", so it was not over-written.
Startup Options - Choose a Default OS to Run at Startup in Windows 8
and am wondering if I should try Options 2 through 4 (1 of)? I build my own PCs so know something about PC's, bt not much about booting to an OS.....
Another options might be installing a third party boot manager, which I have not yet done.
my reason for getting back to Win 7 is to be able to use the PC while I learn and setup Win 8 over time. I went into this believing that getting a multi-boot capability would be very easy.

I've recently made a Windows 8 and a Windows 8.1 installation disc from the ISO images on MSDN. Each image includes Core/Core VL and Pro/Pro VL, 32 and 64 bit editions of each. I have the installation keys for all of these installations, but I don't want to have to type an installation key every time I go to use this disc. I've tried adding an installation key using WinReducer8 (which I do not recommend), but it only adds one key, which means I cannot choose which edition I want to install.
When I made my AIO Windows 7 ISO, I had no issues, as Windows 7 doesn't force you to add an installation or product key; you select your desired edition and you're good to go. Attached Image 1 shows what I'm referring to.
Now, however, Windows 8 has to choose your edition by the product key you enter (well played, Microsoft), and I want to find a way around this.

I bought an Asus g75vw with a preinstalled Win 8 because it was cheap, and afterinstalled an SSD to get some more OOMPH. But after a long time and lots of grief in trying to get the OS transferred to the SSD I managed to do so today due to theog and Paragon 12's clone-tools So I was happy as a clam up until a few mins ago when I discovered that the old 500 gb HDD was gone missing.

I bought an Asus Vivobook S551LB. Paying around 1150 for it, the specs seemed good and I thought it'd be a fairly quick laptop.
Turns out... It's really slow, and freezes a lot.
It was preinstalled with Windows 8, then I updated to 8.1. I'm fairly new to anything past Windows 7 so, 8 I'm completely lost.
I deleted all the bloatware that came with the laptop but it still freezes, so my last resort is to reinstall windows.
I can't because I updated to Windows 8.1 and when I try to reset it says I'm missing a partition.

I was using Ubuntu 14.04 on my laptop before. Now I want to install Windows 8. I have laptop's rescue CD. I get the following error when I tried to install Windows 8 on UEFI using the rescue CD:
"Unable to reset your pc a required partition is missing".
I think I have a problem about partitions type because Ubuntu uses ext4.

I did a factory reset on my windows 8, and it messed up, not completing. so it is now stuck on a cycle of 'preparing automatic repair' and 'diagnosing your pc'.
And I today recieved the windows 8 cd to reinstall the os.
But after I've chosen language, I get error message saying I'm missing 1 of the media drivers.

Alright, so after restarting my Toshiba Satellite L50A16H Laptop (Windows 8.1) it gave me a blue recovery screen,
it stated:
The Boot Configuration Data file is missing some required information.
File: BCD
Error Code: 0xc0000034
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 am trying to install the new develp build of Windows 8 (x86) on my asus eeepc 1005pe. This is a netbook which doesnt even have a cd/dvd drive.
So anyway, I extracted the iso on a bootable usb flash drive. I boot, and when I click install it just hangs for about 10 minutes and then it gives me this error:
I tried setting the bios from AHCI to IDE. This does not work, I even get a bluescreen of death when I boot up in the current win7 sp1 install. But anyway on google I read a lot about this problem and one of the solutions is to put it on AHCI.. but not for me as it was already on AHCI. Anyway IDE is not workin either.
Just recently I installed win7sp1 on this netbook without a problem. I checked the sha1 hashes of the Windows 8 ISO and they are confirmed, so that is not the problem either.

I swapped the HDD with a new blank SSD in T530 and booted it with the recovery USB of windows 8. System boots from the USB and gives refresh, reset, and other options. However, when I select reset ( to fresh isntall the OS on the SSD), it fails saying a required partition is missing. What! I'm using a blank SSD, shouldn't the installer present me with options to format and use the drive rather than erring out?
Is there any better way of installing the windows 8 os on a new blank SSD using the recovery USB?
I do have gParted live USB. If nothing works, I will partition the SSD using gParted and try the Windows 8 recovery USB again.

I have a new HP desktop, 8 months old, with Windows 8. Send To has never worked properly. The only items showing are BD-ROM DRIVE (E), or Removable Disc (F) when a flash drive is inserted.
I cannot find the Send To folder using, Run > shell:sendto, or with Search. I have used Refresh with no result. As the Send To has never worked from new, it would appears to be missing from the software, or the software as written is unreliable. A software update would seem to be what is required to resolve the problem.
From the number of inquiries on line and in the forums, it appears to be a major problem. Can we hope for a resolution when 8.1 is released. It did work perfectly with XP, Vista, and Seven after all.

The computer is an ACER Aspire 3. 4Gb RAM. 500Gb memory.
I've been using the computer for a month and a half more or less and everything went OK only few small problems but 2 days ago. It did not Boot.When starting the PC the following appeared:
Recovery
Your PC needs to be repaired
The boot configuration data file is missing some required information.
File:BCD
Error code: 0x000000d
You'll need to use the recovery tools on your.....
The first thing I did was creating a bootable USB with Windows 8 software, it did not work. SO i used Rufus, it worked and launched the Windows 8 installation and recovery but when I tried to recover, refresh, anything it told me the disk was locked... or anything the only thing I'm able to access is Command Prompt.
I've been trying some commands that I've seen online but no luck so far. Some commands tell me "OK, successfully something" But when reboot and I change to default the boot order and UEFI then the same error appears.

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.

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.

I recently did an update of my machine from Windows 8 to Windows 8.1. The update process did not show any errors or warnings and by the time it finished I was under the impression that everything went smooth.
After the update I was testing the environment and discovered that one of my desktop applications stopped working, I went to the developer's website and indeed I found there is a known issue with their software on 8.1 and to solve it, I had to completely uninstall the software and then install it once more. So I went to Programs and Features in order to do so and to my surprise the Uninstall button was missing from the interface. Right-clicking an item and selecting uninstall from the menu gives a warning message suggesting that the application might have already been uninstalled and asks if I wanted to remove the application from the Programs list. However, clicking OK or Cancel just closes the message box and nothing happens.
So I went and tried to Refresh My PC; Once I clicked Refresh My PC the verification process started and indeed it told my that some system files are missing and that it should take care of it provided I insert my Windows disc. Now since its an OTA update from Win 8 to 8.1 I thought that MS knows that some people will not have a physical copy of 8.1 and so I inserted my Windows 8 Pro System Builder disc hoping it would work, but sadly as you might have guessed, it did not. It told me that I needed the 8.1 recovery disc.
Now I have been looking everywhere for a recovery image to download and use to fix my problem, everywhere I go it suggests that I make my own copy. But how am I supposed to do that if my Windows is faulty and has missing files. I really don't wanna go back to Windows 8 and re-upgrade to 8.1. I have a monitored internet bandwidth and I cannot go and download the 3 GB 8.1 update once more.
How can I repair my 8.1 machine?
I came across this article describing how to get an ISO image for 8.1 with a Windows 8 product Key. However, entering my Windows 8 Pro System Builder (OEM) key in the box fails and tells me that the key I entered is not for this product.

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.

I recently purchased an Asus X551 laptop with Windows 8 but straight the way uninstalled Windows 8 and installed Ubuntu (after creating a Windows 8 recovery drive just in case). I have since decided that I want Windows 8 back as I have found that I cannot use a lot of software on Linux. The laptop did not come with any form of recovery disk or installation disk, the only reminent of Windows 8 I have is the recovery USB that I created from within the OS.
When I plug in the USB and boot from it it brings up the recovery menu with options to reset the PC but when I click it it says something like - "Unable to reset PC. A required partition is missing".

I'am trying 8 hours now to install Windows 8 to an Acer Aspire 5920g.
Problem is that when the usb flash drive comes to hdd presenation point the hdd isnt being displayed.
My guess is that Sata AHCI/IDE controller driver for the 5920g's chipset is missing from Windows 8 installation dvd.
I googled very much and i can only find XP and Vista Sata Drivers while oi need 8's.
Is there an alternative? I must get 8 installed in that laptop.

I have an ASUS VivoBook X200CA that is running a Windows 8.1 Upgrade. For about 5 months, this laptop has been running perfectly without any problems and I have managed to reset the computer many times due to certain errors and problems that have arisen from software and hardware compatibility.
Recently, I went to reset my laptop, it restarted and then it took me to the WinRE screen. I went into Troubleshooting > Advanced Options and I clicked on the Reset option. It then took me through each of the various warnings and making sure that my data was backed up and then, once I had clicked on the "Reset" button, it hung for a bit and then said "Reset has failed - Required Partition is Missing".

Since a few days, I owned a new WeTab to play around with different tablet operating systems.
I'd like to install Windows 8, Android and Ubuntu in parallel and use the new GUI bootloader from Win8 to choose what to boot.
I started with installing Win8 and installed EasyBCD to modify the bootloader. A little test configuration shows the correct function of it.
When I start to intstall Android the fist time, everything was fine, but after installing ubunto the Windows 8 Bootloader turnd from GUI to text mode.
also
bootrec /fixmbr
bootrec /fixboot
common Win8DVD repairoptions
can switch back to GUI mode
is there a trick to get the GUI back, because without Keyboard on the tablet it's quite hard to select an option :)

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.
