Updating from 8.04 to 10.04 from CD

[snhapratyush]

I had Ubuntu 8.04 & Windows Xp installed on by 80GB Hard Disk by giving 40GB each to Ubuntu & Xp. Due to some problem in Windows Xp (nothing new) i had to reinstall Windows Xp. I had taken backup of all data on Windows & Ubuntu fully knowing that Grub would go haywire.

Now i want to install Ubuntu 10.04 on the 40GB that was earlier occupied by Ubuntu 8.04 from CD. But i dont know the procedure plz help me out.

I'm posting the output of sudo fdisk -l

Should i delete all Linux partitions ? What and how many partitions (min.) should i make ? What partition should i use as mount ? Should i use ext3 or ext4 in all partitions ?

How should i go about it ?

Boot to the live CD and use the install icon as usual.
When you get to the partitioning part, choose Specify partitions manually (Advanced) and then when you get to the next page you will see the ext3 and swap partitions for ubuntu 8.04. You can highlight these and edit them to be the new / (root) and swap partitions, or you can delete the old / and make a separate / and /home partition, as well as swap. Everything else will be exactly as you have done before when installing.

Just make sure you avoid doing anything to your windows (NTFS or fat32) partitions and all should be well.
