Windows 10: Windows 10 repair disk which was created does not give option EFI bios to boot from.

I have created Windows 10 64 bit repair disk, and when i boot I press F12 and it gives me options on the boot.


Well, there is option DVD/CD but when I select it and press enter nothing happens, even DVD disk is in the drive, so I cannot start this repair disk.


On the other hand when I created a Macrium rescue media, I get EFI option to boot from and successfully start it up. But I do not want to use this


software since I have a backup a system image into USB flash drive as a network drive, and tried it told me that unable to load, so I decided to use old


fashion way just Windows 10 64 bit system repair disk, but on boot there was no EFI option like with Macrium rescue media disk.


Does anyone know ? Get back,



thanks in advance.

Windows 10 "Create a system repair disk" will not boot

I think i found the problem.

The Pc in question has an EFI bios and when i create a system repair disk,

it doesn't copy the file bootfix.bin in the map \boot on CD.

When i create a system repair disk on another Pc with the same W10 version and

no EFI bios, it does copy the file bootfix.bin in the map \boot on CD,

and this will also boot on the Pc with the EFI bios who had the boot problem !

I think it is EFI bios vendor related, so make sure bootfix.bin

is always in the map \boot on CD.

For me the problem is solved

Mainboard is ASUS Z170 Pro Gaming

UEFI boot options disappeared from BIOS; now getting reboot and select proper boot device

In short, I need to get the system/BIOS to allow UEFI booting of the SSD.

Computer started up today with default BIOS settings.

• Only SSD 1(Windows boot) and SSD 2 were listed in BIOS; HDD 1 and HDD 2 were not visible
• System would not boot. Gave the 'reboot and select proper boot device' message
• Boot menu has no UEFI/EFI (or Windows Boot Manager) entries anymore

I went into Partition Magic/Gparted and confirmed :

• All drives are still showing
• All drives' data is in tact [EFI volume/partition is still listed (and can be browsed/files accessible)]

Gparted print out (note dev/sda2 apparently that is normal behavior) :

/dev/sda1 (locked) EFI System Partition--Fat32--/media/sda1--100.00mb--46.81MiB--53.19MiB--boot,esp
/dev/sda2 (exclamation mark) Microsoft reserved partition--unknown file system--no mount point--128.00MiB--unused spaced--msftres
/dev/sda3 basic data partition--ntfs--/media/sda3--118.58GiB--70.78GiB--47.80GiB--msftdata
/dev/sda4--ntfs--/media/sda4--450.00MiB--327.71MiB--122.29MiB--hidden,diag



As I am able to boot Windows installation from USB, I tried the standard startup repair. It said it was not able to fix any problems.

Next I tried to repair the EFI with Diskpart in the shell:

• sel vol 1 (note that Diskpart states EFI partition is 'hidden')
• assign letter=z:
• cd /d z:\EFI\Microsoft\Boot\
• bootrec /fixboot
• bcdboot c:\Windows /l en-us /s vz /f ALL

It completed all tasks successfully. Unfortunately that did not work.

Other things I have tried :

• Removing CMOS battery and replacing with a new one - my HDD started showing up again after doing this.
• Using the old MBR commands(in hopes it would force the Windows startup repair to recognize and fix a problem)

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd​

• Loaded BIOS 'optimized'/defaults (the system did this already once before, hence why I am in this situation, though doing it manually seemed like an option worth trying. Note that after doing this and restarting the system, HDD's stopped showing again)
• Removed new CMOS battery and left it out of the system for thirty minutes
• Formatted EFI and msftres partitions, then rebuilt the EFI boot records

In summary, am looking to force the BIOS to see the EFI partition on the SSD boot drive, as it is not an option any longer.

 

Windows 10 "Create a system repair disk" will not boot

HansMaasNL,

I have the same problem with my latest computer that I built with an ASUSZ97 motherboard that boots with EFI Bios. I tried 2 different CD manufacturers several times. I finally tried the repair disks that I created on my older ASUS P8P67 MB that I handed
down to my wife and it boots perfectly. Even the repair disk that I created on my Toshiba laptop will boot the ASUSZ97. While my problem was solved, it was definitely bothering me but now that you have explained the reason, I can let it go (not to mention
I now have at least 8 bootable Windows Repair disks that can work on the ASUSZ97). Thanks!!
