At present, I have 2 harddisk: primary master (hda) and primary slave (hdb). hda contains Mandrake 7.2 while hdb contains Windows. I'd like to try out Mandrake 8 RC1 by installing it in a 2nd (blank) partition I've created on hdb. How do I insert an entry in GRUB or Lilo such that I'd have the option to boot from either Mandrake installation? Thank you!
