Thanks for the post! I tried Expert mode which, somewhere along the way gave me the option to skip LILO so I was able to get to the end.
Here's where I'm a bit lost: I reboot, and there's no Linux option. I only have the option to choose the Windows OS's from my first hard drive, not the Linux from my second hard drive. So I rebooted with the boot disc installed, and everything goes through the stages, but just as Linux is about to start, the disk starts thrashing - the screen blinks on and off and I have to ctrl-alt-delete to get out. It's a real bummer because I'm THAT CLOSE to starting Mandrake and taking my first real steps towards breaking the Microsoft chain. Any thoughts?
