One of my colleagues installed Ubuntu on one of the work laptops. it is dual boot with XP. the problem is that linux is at the prefer OS in the GRUB menu. Since he left the company i need to change the grub menu so that XP will be the prefer OS. He forgot the root password so that i can't log in to the linux and change the GRUB file.
Is there a way to modify Grub without logging in to the linux. I know it sounds silly but if i know the root password i know how to change the GRUB file. since i didn't the root password. i am pretty helpless.
Any Help will be appreciated.
