We do the following to boot multiple os': |
| 11 |
|
| 12 |
create a small partition on dev/sda1 that contains just |
| 13 |
|
| 14 |
/boot/grub/* |
| 15 |
in /boot/grub/menu.lst (or grub.conf): |
| 16 |
|
| 17 |
# Imaging Environment grub configuration file |
| 18 |
# Installs in to MBR of first disk, and allows |
| 19 |
# chaning to the other boot options. |
| 20 |
default 8 |
| 21 |
timeout 15 |
| 22 |
#serial --unit=1 --speed=38400 --word=8 --parity=no --stop=1 |
| 23 |
#terminal --timeout=10 --dumb serial console |
| 24 |
|
| 25 |
title disk 1 slot 1 root /dev/sda2 image likely x86_64-rhel4u4 |
| 26 |
# OS root device /dev/sda2 |
| 27 |
root (hd0,1) |
| 28 |
rootnoverify (hd0,1) |
| 29 |
chainloader +1 |
| 30 |
|
| 31 |
title disk 1 slot 2 root /dev/sda3 image likely x86_64-rhel5-ga |
| 32 |
# OS root device /dev/sda3 |
| 33 |
root (hd0,2) |
| 34 |
rootnoverify (hd0,2) |
| 35 |
chainloader +1 |
| 36 |
|
| 37 |
title disk 1 slot 3 root /dev/sda5 image likely x86_64-sles10-gmc |
| 38 |
# OS root device /dev/sda5 |
| 39 |
root (hd0,4) |
| 40 |
rootnoverify (hd0,4) |
| 41 |
chainloader (hd0,0)/boot/grub/bootsect-xfs-sda5 |
| 42 |
|
| 43 |
title disk 1 slot 4 root /dev/sda6 image likely x86_64-sles9sp3-e1000 |
| 44 |
# OS root device /dev/sda6 |
| 45 |
root (hd0,5) |
| 46 |
rootnoverify (hd0,5) |
| 47 |
chainloader (hd0,0)/boot/grub/bootsect-xfs-sda6 |
| 48 |
|
| 49 |
etc... |
| 50 |
|
| 51 |
Then install each dist in it's own partition with no individual /boot partition. |
| 52 |
The chainloader then picks up the grub entry from that partition. I do the same |
| 53 |
with WinXP on my laptop for the few times I boot into that partition. |
| 54 |
|
| 55 |
Typically, though, we only use parted to setup our partitions. And a lot of the |
| 56 |
time we set up our systems as GPT disks with labels. |
