Thanks for you quick reply. I have another problem after I follow you steps:
1) I repartition the disks to be
/dev/sda1 / 4GB
/dev/sda2 /rh80 10 GB
/dev/sda5 /rh72 20 GB
1 GB for swap
2) I installed RedHat Enterprise Linux version 3 on /dev/sda1
3) I installed RedHat 8.0 on /dev/sda2 by specifying / in the partition
After system reboot, it will always boot onto RedHat 80.
How I can boot to /dev/sda1 which is my RedHat Enterprise Linux version
3 which will be latered on install the xen ?
I played around fdisk /dev/sda and it seem Boot flag (*) points to /dev/sda1
Device Boot Boot Start End
./dev/sda1 * 1 510
/dev/sda2 511 1785
Why I can not boot to /dev/sda1 ?
The other option I have is to install RedHat 8.0 first and then install
RedHat Enterprise Linux version 3 last so that I can boot off from it
to continue the xen installation.
Any suggestions ?
I don't use RedHat, so my steps will be sort of vague. You should keep
your replies on list, where other more versed people can respond to them.
Reboot your machine. (You may have to do this several times to engross
yourself in the process.)
Watch it carefully, for signs of a boot loader. I've only seen GRUB and
LILO as bootloaders, but RedHat could use something different. The
bootloader starts after your video card and system BIOS messages. It
looks like you're running SCSI, so you'll probably see a message saying
"looking for devices", after which it'll list your hard drive(s) and
When you see something that looks like a bootloader that possibly says
"loading", try pressing a few keys. Tab and/or Space generally work
here. Sometimes the bootloader counts down seconds(from 30 or less) to
starting a default OS, this will be what you want to interrupt.
At this point, you should know definatively what bootloader you're
using. Run to another computer and google that bootloader.
Your next step is to convince your bootloader to boot with /dev/sda1 as
root instead of /dev/sda8.
You should hopefully see a list of your possible OS'es to boot(it will
probably only show one, even though we all know you now have two.) With
LILO, I believe you just type on the commandline the name of the
instance you want to load then follow it with root=/dev/sda1
I've only had GRUB since I started using Xen, so I don't recall exactly
what it looks like, but basically you need to tell it where a kernel is
it can boot, and what partition to boot as /(root). Fortunately, GRUB
can look into filesystems and help you with filename completion for th
