http://www.linuxquestions.org – Slackware 13 didn't install correctly, and I accidentally installed it on my main hard drive on my Toshiba laptop, now it has the MBR all jacked up. I can't boot from CD. If my external usb HD is formatted in a linux format, I have the possibility to boot from that device, but as soon as I load another linux distro, such as ubuntu or pardus, it won't load, and actually disappears from my boot menu. Slackware is dead it runs into a Kernel problem and locks up and then i'm forced to reboot. Please help! (HowTos)
