well, on a 'used system' the Linux Mint installer is a FAIL - you can assign partitions and crate an fstab yourself, then it goes through the motions, and ends up saying grub was not correctly configured. Meanwhile Fedora boots bit still exist, including the *old* grub menu, no new one anywhere at all. Guess I'll have to wipe the HD completely to get Mint to install... #tomorrow, maybe!
