dual boot with 2 drives

[tomeriker]

I have XP/ Ubuntu on an 80 gig sata drive in dual boot. I have tried in the past to add another linux distro but couldn't get grub to see all the distros.

I have another 250 gig pata drive that I want to use as a knoppmyth drive and do a kinda triboot, but didn't know how to go about editing grub to do that either.

Imagine my surprise when a friend came over and said "oh thats easy, just hit F8 during boot up and choose which drive you want to boot from". Could it really be that easy? YEP! I feel dumb.

So, just in case there is anyone out there that wants to know, I hope this helps.

Now if I could just figure out how to edit grub!

SATA and PATA combination creates problems sometimes.
install other Linux distro in PATA disk and
* install GRUB in MBR of PATA disk. in this way, you have to press F8 key at startup, change boot order to boot up from SATA or PATA disk.
OR
* install GRUB in boot sector of PATA disk. edit /boot/grub/menu.lst file of Ubuntu to add an entry of other distro. you have to edit device.map file too.

i prefer second method coz i find changing boot order every time is a bit cumbersome.
