I was try to upgrade my 6.0 install with a 6.1 upgrade installation. I booted from the cd and started the installation. When it asked what kind of installation: ie custom, upgrade... i choose upgrade. This is where the error is. IT trys to mount hda1. 6.0 is set up on my machine on the second drive. I have bootmagic handle the boot stuff and made a ext2 boot partition on the main drive. It automatically tried to mount that drive and then craps out b/c that is my ntfs drive on my winnt ws 4.0. it then just stops and you have to reboot manually.
