Some network issues left me in a bit of fix during last few days. While restoring everything back to normal, there was the usual 'you know what' blue screen on the Windows installation after which it wouldn't boot. Since I have ubuntu installed as well on my laptop, it is more than 'irritation' to repair or reinstall Windows XP - the GRUB/LILO bootloaders on MBR get overwritten.
Ofcourse one way was to [:http://ubuntu.wordpress.com/2005/10/20/backing-up-the-mbr/|back up the MBR]. The other way was to re-install Windows XP and then worry about [:http://ubuntu.wordpress.com/2005/10/20/backing-up-the-mbr/#499|getting back the bootloader in place]. I went for the latter.
Nice about the whole thing is that installing bootloader is a three (simple) steps affair now :)
