Computer is Gateway Netbook with Win7.
I want to install Ubuntu ,but when I go to the next window after the keyboard section, I cannot find the right combination for the partition designation. I click install on a 50gb partition I made for the install. The page asks for mount points and says no root file system is defined. I put in EXT2 and a / , page told me I should have a section for a swap file. what is the correct information for these boxes? I am installing Ubuntu to learn the linux sys and I certainly don't know inough about it to come up with these commands yet.

You really need at minimum two partitions to run Linux, the root partition (/) and swap. Technically you can do without swap but it's generally not a good idea at all. It's also a good idea to have /home on a separate partition so you can wipe the OS without using your data. So you need to use the partitioning tools to make ext3 partitions for / and /home (why use ext2, it doesn't have joubnralling?) and a swap partition. Doesn't the Ubuntu installer have something that will do this for you automatically using the unpartitioned space on your drive -- I seem to recall that it did (though I can't recall if it will create a separate /home)?

When you choose manual partitioning Advance and than / ext 3 was Ubuntu complaining about it .
That is somewhat strange that she did .
Normally Ubuntu make the partitioning it self.
As soon as know which space on the disk she may use .
If not see the partitioning below
1) /ext3
2) linux native ext3
3) home ext3
4) swap let say 2 x RAM
Linux do need to be on a primary partition

I installed Ubuntu again and it installed without asking for detailed instructions. Used partition 5 AS EXT4
and partition 6 as SWAP. I don't know how to post thanks, but thanks to both of you.

Just press the Thanks buttons under each persons posts
