Installation 10.o4:No root file system is definedCorrect from Partitioning menu

Did you MD5 test the ISO you used to make the installation CD?
Did you burn the CD as SLOWLY as you could?

Both of these are very important.

If you ave then you can choose custom partitioning and partition as below:

For a standard desktop/laptop:

10Gb for / format ext4
2 x RAM amount for swap
the rest for /home

for a netbook:

1Gb for swap
The rest for /

The install will now proceed

Hi :)

Please choose the "Try Ubuntu without changes to this machine" to see if you can get to a working desktop, as this guide shows
https://help.ubuntu.com/community/LiveCD

The Partitioning Section is about stage 4 in the installer so you were nearly there, but it is unusual to get that request which is why we are suggesting you check the Cd in a couple of ways

Good luck and regards from

I am doing the manual partitioning for netbook 10.04. Following the directions, I have done the swap partition. Now I am trying to create the root partition. I put in the size. Now I need to select from the "use as" menu. The problem is that this menu has no "root" choice. In addition to "swap", this dropdown menu has eight choices, such as "Ext4 journaling file system". Which one of these means "root"? Thanks.

Hi :)

That is the "file-system" drop-down menu. Choose ext3 there (or ext4 but ext3 still seems better) and then the next drop-down menu should allow you to choose /

Good luck and regards from

I received ubuntu 10.04 CD today by post.I have already installed ubuntu 9.04 version in my desktop. How to upgrade my OS to 10.04 version.

You need to install 10.04, you cannot upgrade your Ubuntu 9.04 to 10.04

A) ---> made a backup of your relevant data usually your home directory

- Boot your pc entirely from the ubuntu 10.04 live install cd
- select the item "Try Ubuntu..."
- then using gparted, menu Sytem→Administration→gparted (partition editor): delete or resize desired partition to get unallocated space
- Click on gparted apply toolbar item
- Close gparted
- Click on the "Install Ubuntu" desktop icon and when requested please answer to use contiguos unallocate space

Hi :)

Al;ways the best option is to try the new version as a LiveCd before starting to install anything
https://help.ubuntu.com/community/LiveCD

This allows you to see what you will need to work at to get the system working the way you like it but still makes sure you can still access your existing 9.04 for when you need to get things done in a hurry.

I was not keen on the buttons being on the left (Mac) side at the top of windows rather than on the "right" (Windows) side. Eventually i found a simple 1 line code to enter on the command-line and now it is all fine. Occasionally when i have upgraded i have had troubles with my graphics card and been unable to use the system! Using a LiveCd meant i could reboot back into my older system and find out how to solve the issue.

Usually even if i do like the new look and feel and it all works smoothly i still leave the previous system intact and just partition-off a 10Gb partition to install the newer release as an addition to my dual/multi-boot system. Eventually i find i boot into the older one less often or something (usually i allow the newer one to share the same /home afer a bit of fiddling).

Anyway, the simplest and safest thing to do is to try the new one as a liveCd first, before installing or anything.

"Try Ubuntu"
Good luck and regards from

PS i also do this on any 'new' computer before initially installing Ubuntu, especially if it is someone elses machine that they have been using for a while!
