Replacing the Windows XP Bootloader with Windows 7

If you’ve managed to install XP on the same PC that you already had Windows 7 on, you’ll noticed that you can’t boot into Windows 7 anymore. You can use this command to fix that and restore the Windows 7 bootloader:

bootsect /nt60 all

Depending on the partition that you’ve installed, you might need to substitute the drive letter instead of “all”.

Note: if you want to restore Windows XP back to the menu, you can open up a command prompt in Windows 7 and run this command:

bcdedit /create {ntldr} -d “Windows XP”

Using the Automated Startup Repair

Of course, all this command-line stuff is probably not necessary in most cases. You can usually just use the Startup Repair option from the Recovery menu…

It’ll check for problems and probably fix them. If not, then you can always use the command prompt.

Have you ever needed to restore your boot loader to get Windows working again?
