After playing around with partitions and trying to dual boot, with no avail, I decided to put the partition back into 1, like it was before I started (One NTFS with 55GB). I had shrunk the partition when installing Ubuntu, and later, XP. The XP install did not work as when trying to complete installation (after the automatic reboot) the boot failed and I had to use the Vista DVD to automatically repair the boot. This worked fine. After trying and restoring the boot twice, I erased the second partition and merged it with the original. This took about an hour. Now when I try to start, I get the error "BOOTMGR is missing, press any key to restart". This was the message I had gotten previously that I had fixed with the Vista DVD, but now when I try to start the Vista DVD it does not work. The DVD loads files then shows the vista logo like usual, then the screen goes black. After a minute or so, the mouse comes up, but the screen is still black. I have tried restarting many times and the result is always the same. What do I have to do to repair this problem? I was using GParted to edit the partitions. When I flag the partition with "boot" I get a different and more detailed error, but basically means the same thing (That Boot is screwed). Thankyou for any advice you might be able to give.
