View Full Version : Install Ubuntu on one partition and /home on other partition?

Gents, The Newbie has a new problem :-)
On my harddrive I have made a 30GB partition and a 470GB partition.
I THINK I have installed the OS on the small partition and /home on the large partition!
How do I check this?

Thanks in advance

Yep, you have / on a 29GB partition and /home on a 429GB partition.

Hi Cheesemill,
Im not sure what to do when (not IF, but when) I need to reinstall the OS?
How do I keep my /home during reinstall?
Or- shall I start a new thread with this question?

You have to use Something Else or manual install. You choose sda1, select format as ext4, and mount as / (root). That partition will be totally reformatted & new install will be there. And you select sda3, mount as /home but DO NOT format it. Then it will not change anything other than add updates.

Still best to have good backups. If you install a lot of apps, you may want to make a list with dpkg to make it easy to reinstall.
I also have made a few manual system changes to files in /etc. Those would get overwritten, so I make copies into my /home so my backup saves them, but do not auto copy back as a new install may or may not need them or may need different. But since I may want them it is worth saving.

Oldfred's list of stuff to backup May 2011:

from lovinglinux - use dpkg to list installed apps
