Trying to Rebuild bcd on Windows 10 Toshiba Satellite - Nothing Works
I am working on rebuilding the bcd on a Toshiba Satellite E45t-R4100 running Windows 10. The computer originally came with Windows 8, but I later upgraded to Windows 10.
The computer crashed when the battery completely ran out of charge while unplugged. When plugged in and rebooted the computer automatically ran startup repair, which was not successful and showed the standard Windows repair menu. I have done a significant amount of troubleshooting, and I will list the results below.
System restore from a restore point failed.
Running bootrec /rebuildbcd results in "Total identified Windows installations: 0"
Running bcdedit /export c:\bcdbackup results in "The operation completed successfully"
But attrib c:\boot\bcd -h -r -s results in "Path not found - C:\boot"
I tried generally following the instructions here C:\boot missing
And have the following partition and volume information
Partition # Type Size Offset
Partition 1 Recovery 450MB 1024KB
Partition 2 System 100MB 451 MB
Partition 3 Reserved 16 MB 551 MB
Partition 4 Primary 698GB 567 MB
Volume # Ltr Label Fs Type Size Status Info
Volume 0 Recovery NTFS Partition 450MB Healthy
Volume 1 C NTFS Partition 698GB Healthy
Volume 2 FAT32 Partition 100MB Healthy Hidden
Volume 3 D ESD-USB FAT32 Removable 14 GB Healthy
I have reformatted partition 2 and rebuilt the bcd using the following commands
diskpart
sel dis 0
sel par 2
del par override
cre par EFI
for fs=FAT32 quick
assign letter=T
exit
bcdboot C:\Windows /s T: /f ALL
exit
Everything completed successfully but when rebooting the computer I receive the following error.
Recovery
Your PC/Device needs to be repaired
The operating system couldn't be loaded because a critical system driver is missing or contains errors.
File:\Windows\system32\DRIVERS\klbackupdisk.sys
Error code: 0xc000007b
I have recovery media for Windows 10 and tried the commands again just to make sure I didn't miss anything and the computer gave me the same error notice.
By the way, I did verify that the computer has a GPT partition style.
I also ran scan disk (chkdsk) from command prompt which returned no errors of any kind.
If at all possible, I would like to avoid a complete system restore/reinstillation of Windows.
Any help you can give would be appreciated.
