After going back & forth between win7b & F10 installs, I can't get both to live on the same hard disk for dual booting anymore. win7 complains about fedora's GPT disk being unacceptable for installation. win7 blows away fedora's GPT partitions when it installs. Fedora doesn't recognize win7 partitions when it installs. I can't specify exact partition boundaries with windows even if I know what they are, and I can't seem to find any info how to do it in parted either. I have win7 installed in partition 3 in a known location on disk, but if I reinstall f10 (again), it's going to blow away the win7 boot data on the disk. How do I tell grub where to find the chainloader thingy? Can that still even be used? win7 no longer uses ntldr, and I haven't found an updated procedure for this new boot method.
