Looks like a fairly major bug in Fedora Core 2 from RedHat. If you have WinXP installed before you install FC2 grub, or something, will destroy your partition table and possibly other data. There are a few solutions mentioned on the page above and there’s more on slashdot and the Fedora Test mailing list. I think I’ll hold off a few days before trying this release.
Looks like there might be a solution to this problem after all!
