Hello:
I'm writing in an attempt to understand how the SuSE installer will
accommodate my existing installation.
Background:
(1) I have SuSE 10.1 successfully installed.
(2) I have three hard drives connected:
- /dev/sda : the "main" hard drive with SuSE 10.1 and swap
- /dev/sdb : a new drive that is blank
- /dev/sdc : data
(3) I want to leave my SuSE 10.1 intact (untouched) on sda and want to
install SuSE 10.2 on sdb.
OK, the easy part. I can boot from the SuSE 10.2 DVD and install on
sdb. This should be a piece of cake. Presumably an install of SuSE
10.2 on sdb will not touch sda or sdc.
Now, the question -- what happens to the boot sequence??
For my setup today (if I understand this properly), I'll boot from
sda. Upon boot the master boot record (MBR) will be read from sda and
will launch grub on /dev/sda2/boot. The menu.lst file will define the
"presets" and default that I have.
What happens when I install SuSE 10.2 on sdb?
- Will the machine still load the MBR from sda? [I think this is a
hardware/BIOS issue?]
- Will the machine still load grub from /dev/sda2/boot?
- What will happen to my existing menu.lst file? Will it be
overwritten (to only contain a 10.2 option) or will it be
modified/appended (10.1 and 10.2 options)?
The bottom line is that I don't much care, but I do want the option to
boot into my working/existing 10.1 versus my experimental 10.2 setup.
Will the install program handle this for me? Will I need to make some
manual configuration changes after the SuSE 10.2 install?
Thank you.
