Hi,
I had dual boot of win 7 (default) and win 8. Was all working OK until I moved my win 8 system partition to the start of my drive (had partitions either side with no data so removed). Now when system boots, it displays "\windows\system32\winload.exe error. I press F9 to select "boot to other OS" which boots to win 7 OK. I have 2 drives, 1 with win 7 and 1 with win 8. If I disconnect the win 7 drive, boot up to win 8 is fine so I know it's a dual-boot modification I have to change.

Any ideas?

System One

  • OS
    Win 7 & 8
Boot up Windows 7 first, then drive C: would be assigned to Windows 7.
  1. Open disk management
  2. Find out what is the drive letter for Windows 8 OS
  3. Open Command Prompt as Admin.
  4. Type: bcdboot X:\windows ===> Replace X to be the drive letter you found in step 2
  5. Reboot the PC

Hope this helps !!

So the command will be bcdboot X:\windows\system32\winload.exe ?
No. Just bcdboot X:\windows and you have to replace X with the drive letter that you found from Disk Management for Windows 8 partition.
