OS: Windows 10 Pro
upgraded from Windows 7 Pro using free Windows 10 upgrade
Disk: SanDisk 120GB SSD (SDSSDA-120G)
MOBO: H87H3-CM
BIOS: American Megatrends Version 2.15.1236 (0904 09/04/2013)
Replaced the MOBO (same model#) and now Windows 10 won't boot:
BIOS sees the full SSD drive
SSD in a sled on a different laptop shows the drive/partitions are healthy with no errors
EFI partition is active and bootable.
CHKDSK /r showed no errors or repairs/bad sectors
SFC /SCANNOW “did not find any integrity violations”
Attempts so far:
BIOS settings:
OS Select > ("Win 7/Other OS" vs."Windows 8")
Launch CSM > Boot Options Filter > ("Legacy Only" vs "UEFI only")
Launch CSM > Launch Storage OpROM policy > ("Legacy Only" vs "UEFI only")
SATA Mode > ("IDE Mode" vs "AHCI Mode" vs "RAID Mode")
Rebuild MBR using partition utilities on a sled in a different laptop:
AOMEI Partition Assistant Wizard Standard Edition 8.8
DiskGenius 5.2.1
Booth tool say the rebuild was completed. No change.
EasyBCD:
"Reset BCD Configuration" (then manually added Windows 10 back to boot menu)
"Re-create/repair boot files"
Boot from Windows 10 install media:
Automatic Repair>Advanced Options>Troubleshoot>Advanced Options>Command Prompt
bootrec /fixmbr (Command completes with no error)
bootrec /fixboot (can't get past "Access Denied" error)
I was still able to do these commands:
bcdedit /export c:\bcdbackup
attrib c:\boot\bcd -h -r -s
ren c:\boot\bcd bcd.old
Running either command:
bootrec /rebuildbcd
bootrec /scanos
come up with “0” windows installations
I was able to format the EFI partition with FAT32, then run:
bcdboot E:\windows /s C: /f all
This command at least got the BIOS to see the Windows 10 install and try to boot it.
And the next time I booted off the install media and selected "Startup Repair" the Windows 10 install was visible.
I rebooted and tried this, too:
bcdboot E:\windows /s C: /f UEFI
but no change.
Still stuck at the winload.exe error.
I also tried using runas at the prompt, to run these commands as admin but I get
“1060: The specified service does not exist as an installed service”
