\"\"<\/p>\n

You can also try :<\/p>\n
bcdboot C:\\windows \/s S:    (or Just  bcdboot C:\\windows \/s) specifies C: as Windows partition, S: as system partition. <\/code><\/pre>\n
Sometime windows boot partition can lose it drive letter, you need it to be C !!! the simple way to restore it is :<\/p>\n
    \n
  1. Make a full system backup of the computer and system state.<\/li>\n
  2. Log on as an Administrator.<\/li>\n
  3. Start Regedt32.exe.<\/li>\n
  4. Go to the following registry key:\n
    HKEY_LOCAL_MACHINE\\SYSTEM\\MountedDevices<\/strong><\/div>\n<\/li>\n
  5. Click MountedDevices<\/strong>.<\/li>\n
  6. On the Security<\/strong> menu, click Permissions<\/strong>.<\/li>\n
  7. Verify that Administrators have full control. Change this back when you are finished with these steps.<\/li>\n
  8. Quit Regedt32.exe, and then start Regedit.exe.<\/li>\n
  9. Locate the following registry key:\n
    HKEY_LOCAL_MACHINE\\SYSTEM\\MountedDevices<\/strong><\/div>\n<\/li>\n
  10. Find the drive letter you want to change to (new). Look for “\\DosDevices\\C:”.<\/li>\n
  11. Right-click \\DosDevices\\C:<\/strong>, and then click Rename <\/strong>
    \nNote<\/span> You must use Regedit instead of Regedt32 to rename this registry key.<\/li>\n
  12. Rename it to an unused drive letter “\\DosDevices\\Z:”.
    \nThis frees up drive letter C.<\/li>\n
  13. Find the drive letter you want changed. Look for “\\DosDevices\\D:”.<\/li>\n
  14. Right-click \\DosDevices\\D:<\/strong>, and then click Rename<\/strong>.<\/li>\n
  15. Rename it to the appropriate (new) drive letter “\\DosDevices\\C:”.<\/li>\n
  16. Click the value for \\DosDevices\\Z:<\/strong>, click Rename<\/strong>, and then name it back to “\\DosDevices\\D:”.<\/li>\n
  17. Quit Regedit, and then start Regedt32.<\/li>\n
  18. Change the permissions back to the previous setting for Administrators (this should probably be Read Only).<\/li>\n
  19. Restart the computer.<\/li>\n<\/ol>\n
    You can also have problem with EFI boot loader, the way to fix this is to boot from Windows installation as mention above, then issue this commands from command prompt to rebuild the EFI boot operation :<\/p>\n
    diskpart\nsel disk 0\nlist vol<\/pre>\n
    Then Verify that the EFI partition (EPS – EFI System Partition) is using the FAT32 file system and assign a drive letter to it (Assign a letter that isn’t already in use.):<\/p>\n
    sel vol <number of volume>\nassign letter=<drive letter>:\nexit\ncd \/d <drive letter>:\\EFI\\Microsoft\\Boot\\\nbootrec \/FixBoot\nren BCD BCD.old\nbcdboot c:\\Windows \/l en-us \/s <boot letter>:\\ All<\/pre>\n
    Reboot the computer<\/p>\n
