I've a machine with two hard drives. The first one has 80 GB and the second has 120 GB. I'm about to format this machine and install Linux, and I want to install all the main partitions (/, /boot, /usr/, etc.) on the first hard disk drive (sda) and mount the /home and /var partition on second disk (sdb).

Is this possible, and do I have to do something after the instalation? Or is the second hard disk drive automatically mounted? How can I do it?

I won't do it, but is there any problem to mount /boot on the second hard disk drive?

I'm using Ubuntu 12.04.

You will get a faster answer if you ask at a more appropriate site, such as our Unix/Linux sister site. – Code-Guru Sep 20 '12 at 1:39
If this is for a Home-PC, having all these separate partitions is most likely absolute overkill. – Bobby Sep 20 '12 at 6:55
@KenWhite Yeah, indeed. I'm sorry :) – kurp Sep 20 '12 at 18:32

This will be something you have to do post-installation since the Ubuntu installer does not include that feature. I hate to refer to an outside source, but an excellent guide on how to do this has already been written, HOW TO: Create a separate /home partition. Good luck!
