I have two hard drives, one as master with win2k on it, one as slave with Ubuntu(debian) on it. What I want to do is add Slackware 10 to the slave drive with Ubuntu on it, but every time I try it overwrites the mbr and hosed Ubuntu so it won't boot. How do I add another linux distro without loosing my current distro? Oh yeah, I only need just one swap on the entire drive for all linux distros, right?

Tricky...
I'd try telling slackware not to install a bootloader, and then do that manually afterwards.

Alternatively, you can try allowing slackware to instal a bootloader (which is it, by the way? lilo? grub? something else?), and then tweak its configuration to also load ubuntu.

Groetjes,

if you mean your root partition gets overwrited and you cannot create two root partitions (/ partition), then...might it help to create the first distribution's partitions normally, and for the second, not to create / but something like /two instead. and then set it to be mounted as / or something..I'm pretty sure you can find docs here concerning the installation of two linux distributions side by side...

another tip: why not install windows and linux on one HD, and the other linux on the other HD? that way you can give both linuxes / -partition, without having the problem of two identical mountpoints on one HD?

What it actually does is overwrite my bootloader, which is grub, and slack uses lilo. Once it does that I cannot get Ubuntu to boot again, slack does not seem to like the idea of using grub as a bootloader, and I don't like lilo.

use liloconfig and add ubuntu to the bootloader.
