Hey, I would like to try out fedora 10 on my machine to see if there are any problems. However, i don't know how to properly configure grub. I have ubuntu and XP installed, and i want to install fedora on a different drive to test it out etc.

To make this clear:
sda partitions
XP (sda1)
/boot (sda2)
/ (ubuntu) (sda3)
/home (sda5 iirc)
swap (sda6)

sdb
/Data (sdb2 oddly enough... )
/ (Fedora, installed, but i didn't install grub with anaconda) (sdb1)

both linux os'es are 64 bit

any ideas and/or a guide on how to this? I tried google my self and didnt get anything useful .
