It's amazing that this issue has been around since Fedora Core 2, and it is still present. I have a new PC with an AMD Athlon 64 processor, and it came with XP Media Center Edition installed. Using Partition Magic, I created a Linunx partition. I started the install of FC5 x86_64 from a DVD and it seemed to go well. When grub came up, it listed only FC, but using the down arrrow key, I was able to choose "other". A restore program came up, and after trying several recovery attempts, I was forced to do a complete XP reinstall, so I'm back to square one.
I've seen plenty of "try this" messages around the internet, but is there an authorative, up-to-date, and complete explanation of this problem, and how it can be avoided or fixed?
