Lately I've been having trouble restoring my PC after uninstalling GRUB, and an Ubuntu install from it. Usually I don't encounter any problems when doing this, but this time is different. My Windows XP (NTFS) partition is listed as "Other" in Partition Magic, and "Unknown" in GParted rather than "NTFS".

How can I gain access to Windows partition once again? I am more than willing to provide any information, and run any tests necessary to produce said information in order to find out what's going on here. My apologies if this is the wrong place to ask such a question. I have heard nothing but good about Superuser, and decided to give it a shot. Thanks!
