Installing Ubuntu on a separate hard drive from Windows

Posted 28 September 2012 - 04:15 PM

I have two hard drives. One is for Windows and the files I have accumulated over time. The other hard drive is an empty hard drive that I want to use to install and use Ubuntu on. I have the Ubuntu 12.04 ISO disc and I booted with that disc. How do I install Ubuntu on the second hard drive (disk1 in Windows (disk0 is Windows and disk1 is empty), sdb in Ubuntu)?
Is This A Good Question/Topic? 0

Unixes name their hard drives with /dev/sd(letter). First one sda and the second sdb. Linux in general can recognise windows partitions (however be careful).

Ubuntu is good for this and it will give you many options. I would either let it automatically install on your second drive /dev/sdb or manually partition it (if you feel comfortable).

If you do manually partition it I recommend a partition for / and /home and depending on the amount of ram 4gb or less a swap partition.

I tried selecting /dev/sdb - this is the empty hard drive. I got this error:

Can you open a terminal window & type df? This will show the file systems. You can also cat /etc/fstab

Instead of selecting /dev/sdb, should I select /dev/sdb1?

Ok so what you want to do is format /dev/sdb1
to a ext4 filesystem (or whatever you prefer).
Then during the installation you need to set it to the root partition.

I am currently "Trying Ubuntu" from an ISO on a disc.

ubuntu@ubuntu:~$ cat /etc/fstab
overlayfs / overlayfs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0

Alternatively, could I select "Erase and use the entire disc" and select my empty hard drive?

I heard that some type of file system was better than the others. I think it was that ext4 was better than nfts. What do these mean, why is ext4 better, should I change it from nfts to ext4, and how would I do that?

Ntfs is a windows partition, while ext4 is a linux partition. Ntfs was nit made to interface with the linux kernel and as a result it cannot be used as the filesystem that your system is installed to.

So I should convert the empty hard drive's file system to ext4? How do I do that? Would choosing "Erase and use the entire disc" do this automatically? How can I be sure that /dev/sdb is the empty hard drive?

I just want to be darn sure I am doing this right...

You can use cfdisk don't touch anything just look and it should show you the partition table.

If it matches the table of your disk start the installation.

If it's empty, just format it. No sense in converting an unused, otherwise empty file system.

I find GParted Live CD to be particularly helpful when dealing with partition stuffs.
