Want to boot from two drives with one grub menu. OPsyses are
XP-Fedora and UBUNTU
Here are the facts or info that I gathered.
Booting from /dev/sda with UBUNTU on /dev/sda it boots correctly, it has the
chain loader to Windows XP on /dev/sdb. which boots correctly
But I also have Fedora 12 on /dev/sdb which Ubuntu did not pick up.
UBUNTU uses the new GRUB2 program
Fedora shares /dev/sdb with XP and has the old grub program
If I boot from the /dev/sdb, it does not boot the UBUNTU system.
If I boot from the /dev/sda it only shows XP as the other OPSYS
Can you Help?
Here are my attempts using /dev/sdb (fedora disk, with old version of grub)
a) Added (hd1) as /dev/sda in the file device.map which follows...
=======================
# this device map was generated by anaconda
(hd1)
/dev/sda
(hd0) /dev/sdb
========================
b) Using Gparted for /dev/sda I extracted the following.
/dev/sda3 Ubuntu /boot UUID db3af0cf-ba7b-432b-b5ab-eda6ef4a1215
/dev/sda2 Ubuntu Extended
/dev/sda5 Ubuntu / UUID cab60453-6be1-44df-b71b-274b33f31c40
/dev/sda6 Ubuntu /swap UUID 1957417e-942c-41db-91e1-29b7d11471f6
/dev/sda1 UBUNTU /opt UUID c83da02d-6ebc-43f4-9f43-688248e0dc95
and using Gparted for /dev/sdb
/dev/sda1 Windows XP UUID D0A08CCDA08CBB8A
/dev/sda2 Fedora /boot UUID 256c49d7-a042-4c7c-8803-997cb6871625
/dev/sda3 Fedora /swap UUID
ff07cb9d-7f8b-4a9a-954c-9ddff8986763
/dev/sda4 Fedor / UUID 05ba94a0-4894-48dd-b3f3-96186cc6b541

==================================
I tried root (hd1,2) as I believe the Fedora Grub counts from Zero, whereas the
New grub counts from 1.
Any suggestions.
Do you think it is worth trying to use the new grub2 from UBUNTU?
