Hi All, I am somewhat new to grub and dual booting. I had fc5 86_64
and was very pleased with it's performance (more likely my ability to
perform on it) so I decided to try dual booting fc5 and fc6 and when I
saw the "chainloader +" come up...I was at a loss. I manned and
searched but everrthing I found was to do with xp. I have 160g and
should (I think) be able to put many distros on thier. Any pointers or
help would be appreciated.
The install that you want to be the master controller of booting should
be installed in the master boot record. The secondary install should
have grub installed in the booting partition.
My setup is as shown below. The install marked as HDB is my Development
install and I chose to install grub in /dev/hdb1 and the first partition.
FC6, the controlling installation is installed in the MBR and XP is
chainloaded.
This setup works great for me, except Dell or for some other reason, the
slave on the primary controller was disabled in BIOS. Fedora recognized
it, but grub did not with the funky BIOS setting. It should work if your
BIOS settings as not crazy as was mine initially.
Choose the advanced boot loader option during installation and Edit the
Primary installation grub to add the chainloader entry for your new
install. I did not add the swap on the primary installations LVM, the
installer added this entry.
