I've tried a number of Linux distributions on my Toshiba Satellite 1405-s151, but they have not done well. Most didn't even install, except minimally. I did, however, manage to resize the Windows NTFS partition (which I am going to keep, because I like Windows XP) with QTParted and create the correct Linux partitions in the space left over. A minimal Mandrake distribution now resides on the HDD, but it is pretty useless (can't connect to the internet, for example). Now I want to install Knoppix (which can). When I go through the installation process, however, it tells me that there is no free space. I'm assuming that I'm going to have to uninstall Mandrake and give that space over to Knoppix. That would be my preference, anyway.
Can I do this in an easy, simple, kind, newbie way that won't damage the boot loader (will it scream when it finds that Mandrake is gone? How will I tell it that Knoppix is now there?) but will still get Knoppix onto my hard drive?
