I have 2 hard drives in my computer, one is an XP, and the other is an Ubuntu. I tried to remove a hard drive, and insert a friend’s temporarily, but it didnt work, and when i put everything back the way it was, and booted, it said something about a “invalid disk” so i inserted a Hiren’s Boot CD, and said to “boot from disk” everything worked perfectly until i took out the CD, so i tried to restore the MBR. it worked, and now i can boot without the CD, but now my computer doesnt dualboot with the ubuntu (like it used to). is there a way to select the ubuntu to boot (i think that one has the MBR for dual boot). or a way to add ubuntu to the XP MBR so it asks to dual boot?
