Hello!
I need some halp with installing ubuntu 9.10 (x86-64), but I'm not too much comfortable with linux, so I don't want to mess something up.
The story goes like this:
I have CentOs already installed. The computer has 2 identical 1TB HDD and CentOs
is installed using software raid 1, with 500 GB per HDD used.
When I try to run Ubuntu 9.10 CD installer, it recognizes the partitions,
but does not recognize that CentOS is already installed.
I need the Ubuntu 9.10 just for testing, so I am looking at the simplest method
to reliably install it without messing up the CentOS. I don't need RAID 1
for Ubuntu 9.10 partitions, although I wouldn't mind having RAID 1.
But the simplicity of installing is the priority.
I also downloaded the 'ubuntu 9.10 alternate CD', but didn't try it.
From what I read at the forums, I should probably install Ubuntu without
the bootloader, then point the CentOs's bootloader to run
Ubuntu when appropriate menu item is selected. Or install Ubuntu with bootloader,
then point this bootloader to run CentOs.
Anyway, I don't even know whether my CentOs has the bootloader,
because my friend did the install of CentOS.
Anyway, the kind of help that I need is very specific, like what Ubuntu installer to use
what lines to insert in which file etc... (I know how to create partititions, that's not a problem)
Here is some info that might be helpfull (all from CentOS):
