Most of the faqs/how-to for dual booting assume windows is installed with 'nix being installed in unpartitioned space.
I need to go the other way, i have wheezy installed and need to install xp, so, i'm going to resize a partion, format fat, install windows, and then ...?
does windows install over-write the MBR? Can that be fixed (Back to grub)
I guess I don't mind reinstalling wheezy after installing xp, but that seems like a sledgehammer
