Thanks Rick. Do you think the fact I can't boot into Windows has
anything to do with lvm? My problem came about when I was trying to
resize my ntfs partition with Partition Magic so I could create a fat32
partition. Unfortunately PM crashed during the resizing process and I
could no longer boot Windows. Any thoughts as to what I should try to
figure out the culprit? I'm using GRUB as the boot loader.
