Well, I wasn't thinking when I did this. I had a triple booted computer with XP, Vista, and Ubuntu. I wanted more space so I booted off of the Ubuntu CD and deleted the XP partition and resized the Vista partition to include the new space. Ubuntu said everything went fine, but Vista won't boot now.
Is this because the MBR (or something) was on the XP partition?
I researched a great deal yesterday and found others with similar problems. Some peopl think Gpartition works perfectly with NTFS partitions and others not so much.
I ended up giving in and backed up my data and did a format and reinstall. I couldn't even boot off the Vista DVD until I formated the drive. Must have been something with the boot loader, MBR, or partition I would think.
