I used Partition Magic to create partitions for a Linux Mandrake installation on a second 18-gig hard drive. The program allowed me to create two "Linux Ext2" partitions and a swap partition where I used to have a logical drive of 2 gigs. The installation seemed to go fine. But now when I boot the OS I see a couple of messages that say "are you trying to mount an extended partition instead of some logical partition?" Everything seems fine until I log in as a user and choose "KDE." Then the screen goes black. What does this sound like?
