![]() ![]() ![]() Apparently, because it knows where it SHOULD be, this breaks /SysStore- and actually, that's probably correct behavior, because otherwise you'd put it in the wrong place.It therefore knows WHERE TO LOOK for the BCD file- however, it either somehow has the location wrong (not this problem, but similar) or the BCD has been deleted.Windows can tell you're set up for EFI (you have booted the DVD via a UEFI boot, you have an EFI partition, etc.).If ALL of that applies fairly closely to you, here is what MAY be going on: You've tried to use MountVol to mount the EFI partition, but it doesn't even show in the list, so you can't.You have a hunch that it knows where the store is- or should be- but you can't find it. You look into the /SysStore option, which sounds right, but you can't get it to use another store because it's "ambiguous". To re-enable Hyper-V, I also had to run the following from an Administrator Command Prompt within Windows after rebooting: bcdedit /set, and that you SHOULD be able to import it using /Import. There isn't a lot of reliable info about fixing UEFI/Windows 8 at the time of writing. The localisation defaults to US English, or use en-US. The /f ALL parameter updates the BIOS settings including UEFI firmware/NVRAM, /l en-gb is to localise for UK/GB locale. Use bcdboot.exe to recreate BCD store: bcdboot c:\Windows /l en-gb /s b: /f ALL Then assign a drive letter to the EFI partition: DISKPART> sel vol 3ĭiskPart successfully assigned the drive letter or mount point.Įxit DiskPart tool by entering exit and at the command prompt run the following: cd /d b:\EFI\Microsoft\Boot\ĭelete or rename the BCD file: ren BCD BCD.bak Volume 3 FAT32 Partition 260 MB Healthy System Volume 2 WINRE NTFS Partition 400 MB Healthy Hidden Volume 1 C NTFS Partition 195 GB Healthy Boot Volume # Ltr Label Fs Type Size Status Info Go into the Advanced options and run the Command Prompt.Įnter diskpart to use the DiskPart tool to ensure you have all the right partitions and to identify your EFI partition - the key thing here is that your EFI partition is formatted as FAT32: DISKPART> sel disk 0 using BCDEDIT I got it to find and launch the Windows partition but it refused to cold boot or would not "keep" the settings after a 2nd reboot or power off. I've spent a lot of time trying to get my Windows 8 PC to boot again after cloning to a new SSD and try to summarise how I finally got it all working -įirstly, boot from a UEFI Windows 8 recovery disk (CD/DVD/USB) - I found that the automated recovery process didn't find the correct Windows partition, nor when I managed to add it to BCD settings would it make it reliably bootable e.g. ![]()
