I think there are some reasons not to install on HD.

Toshiba Satellite c655d-5243; ((AMD64)) C-50 Dual Core/3GB DDR3/AMD graphics card/
Installed Linux Mint 12 flawlessly to the full drive, rebooted and inserted the Knoppix 6.7.1 CD with .ISO on it, BIOS boot from CD/DVD, ran {{{ran KNOPPIX64}}} from the prompt instead of local boot because the local boot will crash just like the Install. So I GPARTED, ripped off 40GB of Linux Mint 12 partition; ripped another 3GB for swapspace, formatted to REISERFS the other 37GB. Install went fine. Reboot to Mint 12, Sudo Update-grub...all fine, reboot in GRUB and chose the Knoppix partition for boot, booted up to a screen listen to what I describe because I can't find anything on Google about this specific problem.
It's a mostly white background, but the top 150~ pixels or so, is a black background, with white pink and other colors scattered loosely, the white background is darker pixels alot of red or pink, tightly knit, and the mouse cursor is a white moving block of about 120 pixels with black scattered about, and I get initiating startup sequence. NOW REMEMBER, I WAS ABLE to get this same problem when booting without the parameters "knoppix64"...so what do I do? If anyone can help please and thank you. Thanks all for reading. -BEBO
