View Full Version : [ubuntu] Wiped out Windows bootloader

April 28th, 2012, 02:15 AM

I'm running Ubuntu from an exteranal USB HD. My reason for doing this is so I can carry my personal computer (USB HD) with me on my work trips and just use my work laptop as the hardware.

So I was upgrading Ubuntu 12.04 through the terminal and was prompted to install a GRUB because it couldn't find it on all drives. I selected the windows drive by accident and it removed the bootloader so I can't load windows unless I boot it from the GRUB on my HD. My question is; can I fix/repair/replace my WindowsXP bootloader on my work laptop without having the CD?

You can manually reinstall grub2's boot loader to the external, install Windows or a Windows workalike to the internal, but grub also remember where to reinstall on updates, so you should update that also.

This goes thru all the process.

Or you can do parts manually:
