Setup Installation :: Unable To Find Windows Boot Manager In UEFI BIOS?
Jul 24, 2014
Yesterday, after many, many problems with my computer, I finally decided to reinstall Windows 8.1 Pro onto my ASUS X200CA netbook. However, after backing up and reinstalling the OS, I found that when I tried to disable "Launch CSM" in my BIOS, all of my boot options would disappear and my laptop would continually boot into my BIOS. When I re-enabled "Launch CSM", the boot options would reappear - however, it had not included the "Option #1 - Windows Boot Manager" that I had seen in my other installation.
After creating a UEFI bootable USB thumb drive with Rufus (using Windows 8.1 Enterprise ISO x64), for a Dell Optiplex 3010 (configured as UEFI only, no CSM, latest firmware version, Windows 8 installed), I didn't see a USB boot option, so I tried to add one manually. Unfortunately I erased the existing boot option (boot manager) by mistake. Although there were two boot options for PXE booting, the machine will not start anymore, even when there is an active WDS server on the network.
I also see Led's 2 and 3 lighting up, meaning according to the manual 'hardware ok but bios possibly damaged/corrupt'.
I understand I cannot start the machine from a bios boot disk because of GPT partitioning, and the UEFI USB boot disk I made might be corrupt (as it didn't show up as a boot option), however I don't understand why it won't boot from the PXE network card, as these boot options are still there.
I just bought a copy of Acronis True Image 2013 with Plus Pack. It appears that this is all I need as True Image will install the new motherboard drivers as part of the migration process. But do I stay with MBR or move to GPT?
Presently both Win7 (on a 120GB SSD drive) and Windows 8 (on a different 120GB SSD drive) are both MBR format. I don't want to start over from scratch. That's why I bought the Acronis 2013 with Plus Pack.
I have windows 8.1 installed on 120gb ssd. I also have a 1tb HDD too. So I was trying to install Hackintosh/Linux when I noticed that the System Reserved partition was on my HDD instead of the SSD. So, I used easybtc to migrate my boot files to my SSD. I deleted the system reserved partition. Now I want to convert my BIOS to UEFI. I have Z87 pro mobo.
I tried this tutorial: [URL] ....
But it seems to be geared at the C drive, where I don't have room for that 350mb as disk utility wont let me shrink it.
Edit: would downloading a third party partitioner, shrinking C about 350mb, or whatever is the minimum, and then use that new space as described in the guide work?
Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.
When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up Windows 8 just fine. What I'd like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under UEFI.
Have a toshiba laptop with the UEFI encrypted windows 8 key. The hard drive was broken as it was dropped. No sticker on the bottom as is now microsoft policy. Download of the windows install needs the windows key. Cant get it as it's encrypted. Found generic windows 8.1 keys which worked but it said it was the wrong key for those installs. Generic windows 8 keys don't work for the download. Going around in circles and not sure what to do.
I just built a desktop with a sabertooth x79 motherboard, and am running Windows 8.1 pro 64-bit. When I click the UEFI BIOS Firmware live tile via the change PC settings>update and recovery>recovery>etc. my computer reboots normally to Windows and will not open BIOS. I have tried accessing it using the delete and f2 keys, but this does nothing either.
I am up to date in terms of my BIOS, and am definitely running UEFI and not legacy.
First, some context: I have a Dell Inspiron 15R SE that came with Windows 8.
I've managed to get a working dual-boot system with Ubuntu 12.10. I can't remember exactly how I done that, but I remember that I had to disable secure boot. I think that the boot configuration those days was:
Secure boot: DisabledLoad legacy option rom: EnabledBoot list option: Legacy
This "configuration" worked perfectly for 6-7 months.
Then, one day (last week, can't remember the exact day), when I was using Windows 8 the computer crashed. I hard-rebooted and got this screen:
After executed boot-repair from a Ubuntu LiveCD dozens of times I've decided to eliminate Ubuntu temporarily and focus to get a system with Windows 8 working nice.
Then I used my recovery DVDs to recover the system. Yup, Windows has booted. But when I restarted first time I got the same error. Then I, digging a solution, pressed F12 after a reboot and got here:
The highlighted option allows me to boot into Windows 8. So I went to boot options (F2) and changed the following configuration:
Load legacy option rom: DisabledBoot list option: UEFI
Now I can boot directly to Windows without need to press F12.
But my objective isn't complete. I want to erase all Ubuntu entries from the seconds image and restore the legacy boot from the first imagem (because they worked before).
I did two things:
I erased all partitions related to Ubuntu (root partition and home partition).I created a Windows recovery disk (not a system recovery disk).
I used the recovery disk to run the automatic recovery procedure (I forgot the exactly name). I've runned it at least 10 times with no success. Then I went to command prompt to try the famous triad: bootrec /fixmbr, bootrec /fixboot and bootrec /rebuildbcd. Still, no solution.
Originally my laptop came with Windows 7 and when i looked at disk management my disks were formatted with UEFI schema. One of my friend gave me a UEFI bootable USB drive loaded with Windows 8. So, i thought why not give it a try. So, I created a backup of my OEM Windows 7 and saved the iso files in a seperate external HD (created twice just to be sure . Now, i decided to load the Windows 8. Booted into the BIOS and there is an option to select the USB drive along with the UEFI option for that USB drive. I selected the UEFI option but some reason it does not boot into UEFI.
So I decided to select the standard USB install and this option let me install windows 8. In the process of installing i formatted the partitions and made a single partition and installed Windows 8 on it. I am guessing now the drive is not GPT but MBR. I also noticed that his installation USB disk had an option to select either 32bit or 64bit of Windows 8... Would Microsoft create a same iso file with both versions? I am guessing he created the USB from a illegitimate source.
I am planning on purchasing Windows 8 Pro version as an iso but wanted to be confident that it would work with UEFI architecture.
Questions: 1. Why would the system NOT boot from UEFI? 2. If I download the legitimate iso from Microsoft and wanted to install Window8 Pro via UEFI, I am sure i would have to format my SSD to GPT and how would i go about formatting it during installation? 3. How would i create a recoverable USB for my iso image i created for Windows 7 via ASUS AI Recovery. Do I need to follow the same procedure as stated in creating bootable USB disk (i.e. FAT32 system) via diskpart utility?
I have an Asus S200E and I had been messing with linux and trying to install it alongside windows 8.1 with no joy.After a while I gave up but i've had a few issues with my laptop and wanted to either refresh or reset it.
When I try to refresh I get a message saying that the drive is locked and when I try to reset I am told the recovery partition is missing. I guess I must have done something when attempting to install linux that has caused this problem however when I open up the partition manager the recovery partitions are all still there.
I recently bought a new SSHD for my laptop and after initial problems with trying to install Windows in UEFI, I turned to Legacy and that worked. But now when I change it to UEFI, it just comes up as "Operating system not found".
I've made a UEFI Win8PE by WADK , then burn it to a CD. I boot normal and I can see X:WindowsSystem32.
I use EasyBCD to [Add New Entry] to append new boot item to existing Windows 8. The boot menu becomes like this :
Windows 8 Win8PE
But the Win8PE fail to boot with error message like insert Windows disc again ...... in the primary black and white screen.
Should I not to use EasyBCD to [Add New Entry] ? As I do the same thing in BIOs + MBR harddisk that booted perfect. In UEFI + GPT partition , do I better not to use EasyBCD , instead to use BCDEDIT , if so , what's the command line to do this with bcdedit ?
I ended up managed to be able to boot into windows after i swapped out my motherboard and CPU to the new ones and everything seems to be working as it should, windows automatically installed the intel drivers and all my old programs and settings are there perfectly.
I can only boot into windows if i select my backup drive as #1 boot device in the BIOS, the SSD isnt even on the list.
The thing I don't understand lies in that, if i select my SSD as priority, where the directory of windows is installed, i get a bootmgr missing error - I've tried the various methods of recovering this using the cmd and a windows installation disc.
This isn't a huge issue but it's really tripping me out as to why this is occurring? I initially had some issues getting windows to boot so i installed a clean windows8 on this backup drive, i didnt change any settings at all. was only making sure that the SSD was being recognized and i hadn't corrupted it somehow. is it possible that the backup drive boot manager is directing it to the SSD.
I 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 Lenovo laptop that came with Windows 8 pre-installed. I decided I want to dual boot with XUbuntu.
I shrank my partition and left space for the linux distro. I installed xubuntu into the free space, and even set the bootloader installation to be in that partition as well.
Then after installation, I only get the GRUB bootloader. How to get Windows 8 back and I finally be able to boot into either OS.
However, I have lost the blue UEFI boot manager that Windows 8 should display.
So I get EasyBCD on Windows, try lots of options to regain an original boot manager. But instead of the typical blue UEFI screen, it created a black screen with my boot options (and the linux option doesn't boot from there).
So to summarise, my boot sequence is like this: -Switch on laptop -See GRUB, with default pointing to Windows. I am able to boot to linux from here. -Click Windows and then see Windows Boot Manager (black) with Windows and Linux -Click Windows and it boots. Click linux and get an error.
I have secure boot enabled, and I installed xubuntu in secure boot mode.
I just install windows 8 using BIOS , but now i want to change it to UEFI boot. so i followed steps below
1.create and format a new FAT32 partition K:
2.my windows8 is in I: so , i use this command bcdboot i:windows /f all /s k: and succeeded.
3.i checked with the bootice about the BCD in my K: and found it indeed point to i:windows just like the picture below [URL]
4. and i restart, choose uefi boot in BIOS configuration and it showed like this: [URL]
5. i checked my k:/windows/system32/ , there is a winload.efi file... [URL]
The most strange thing is that i've copyed my winload.efi to other computer which is already in UEFI mode , and also i've copyed it in my virtual machine, it works fine! So my winload.efi should be OK.
I've downloaded a legal iso from MAPS, i ve slisptremed all latest updates into it with Windows download integrator (it uses dism afaik) , then the problems comes in - i cannot use USB as my install.wim is 4,8 GB. I ve burned a Dual layer DVD with Windows 8 stock recorder and the PC doesnt see the DVD drive as bootable. When using stock it boots uefi from pendrive without any problems. How to make this updated iso boot into UEFI mode ?
1st partition is Win7 SysPrep and the 2nd partition is Windows 8.1 Sysprep. I install Win7 and press Ctrl-Shift-F3 to form SysPrep, same as Windows 8.1 in 2nd partition. I made this becuase I've 25 Dell new Windows 8.1 Computer which are UEFI. I want to clone it to the other 24 Dell computers.
CASE 1 : 2 different partitions with 2 different Windows : --------------------------------------------------------------- If I install both Windows like above, when Sysprep Generalize Win7, it works fine. But if I SysPrep Generalize Windows 8.1, it's fine also, but never can boot again back to Win7. The start boot option is like this : Windows 7 Windows 8.1 If I choose to boot Windows 8.1, it's fine. If I choose to boot Windows 7, it ever boot to Windows 8.1. It means nomatter I choose to boot which Windows, it all goes to Windows 8.1 ?
CASE 2 : 1 partition for Win7 + Win81.VHD : --------------------------------------------------------------- I install Win7 (C and press Ctrl-Shift-F3 to form SysPrep. I create a Win81.VHD in Drive D: , imagex Windows 8.1 install.wim in it. Also press Ctrl-Shift-F3 to form SysPrep. Sysprep Generalize Win7 is OK , SysPrep Generalize Windows 8.1 is also OK. But after that I can only boot to Windows 7 fine, when choose to boot Windows 8.1 , it always restart and back to the boot menu ?
So I've searched, and I've tested, and now I'm about to turn my laptop into a frisbee and never buy a Samsung PC again. In short, I bought an ATIV 7 whose previous owner had downgraded to Win7. I wanted to put Win 8 on and I have a volume license as well as the OEM key so I burned the ISO (actually 2 different ones) using every method I could find (ImgBurn, Rufus, Iso2Disc, Win7 Download tool, etc.) It became clear that the USB needed to be formatted FAT32 with GPT filesystem, however in UEFI mode it shows the USB but won't allow me to select it - it just flashes. If I set it back to CSM and UEFI I can make a USB boot, but even if I use diskpart to clean the drive and convert to GPT it will fail to install because it detects I didn't boot in UEFI mode.
Here's the deal. When I'd installed it earlier this week in CSM and MBR mode, and then converted to UEFI it worked fine. So....I tested several recovery programs we use at work to make sure they'd restore it okay via bootable media. Paragon, Aomei, Macrium, Lazesoft - all boot media failed. ONLY True Image 2014 DOES ACTUALLY BOOT in UEFI mode on my laptop. The only thing I can figure is that the way WinPE 5 or 5.1 (whatever it uses) is set up on it agrees with my laptop. So how I can modify the Acronis recovery media or create similar WinPE media that might actually boot on my laptop.
It has an ASUS M2N-E motherboard with an old single core AMD Athlon 64 (I cannot remember which model specifically).
Last week, I provided him with a couple of old HDDs and 8GB worth PC-5300 DDR2 667 MHz RAM. We also installed Windows 8.1 64-bit, and other than the CPU being a single core and a bit slow, things were proceeding relatively smoothly.
He has an NVIDIA Geforce 8500 on the board, and he's ordered a PNY-made Geforce GTX 650 that's on it's way at present.
He's wanting to upgrade the CPU to the AMD PHENOM X4 9950, so we've been periodically meeting over the past couple of weeks to perform surgery on this old machine.
At any rate, we found that to update the CPU, we needed to update his BIOS from the one that was installed, which was at revision 0502. The needed BIOS revision for the CPU was 1504, but would also work with revision 1701.
After jumping through several hoops to update the BIOS, we updated it to 1701. However, since then the machine will not boot into Windows 8.1. He gets an instant BSOD. I did not see the error code, so I cannot say what it was. He told me that he's attempted to do a repair install to no avail. The repair attempt results in a constant loop of the machine rebooting and BSODing.
At any rate, here are some URLs that detail the board specs and the list of BIOS revisions for that board.

I had a bit of a problem with Malware which led me to reinstall windows 8. I had also at the time been trying to install Linux to dual boot beside it. However, upon reinstalling I got the annoying watermark saying "Secureboot isn't configured correctly." Having decided I would rather remove the watermark and having gone back into the BIOS (with a reinstall) and trying to enable secure boot I get a message - "CSM is Loaded! Disable the CSM via Setup and repeat operation after Restart".
However there is, as far a I can see no option to disable the CSM in my bios - I've tried disabling anything related to Legacy and reinstalling both Ubuntu and Windows 8 as well as wiping the drive and jumping the CMOS as well as updating the BIOS.
I've tried every permutation in the BIOS. Could possibly be an incompatibility with graphics card, but wouldn't know where to start on that end if it is.
I tried changing inf file and it detected the required audio card driver, but it shows that device cannot start. It's Cirrus Audio CS4206B (AB83) sound card, but without emulation it shows it as intel audio card. It would be easier to get back to bootcamp, but I really want to make this work.
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 (?)
