Hi!
I am a newbie in Linux. I first instaled Red Hat9.0 as dual boot with Windows XP on the same hard disk(60Gb with 30Gb for XP and 30Gb for Red Hat) and my configuration looks like:

[root@root]# fdisk -l

Disk /dev/hda: 60.0 GB, 60022480896 bytes
255 heads, 63 sectors/track, 7297 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 3649 29310561 c Win95 FAT32 (LBA)
/dev/hda2 3650 3662 104422+ 83 Linux
/dev/hda3 3663 5094 11502540 83 Linux
/dev/hda4 5095 7297 17695597+ f Win95 Ext'd (LBA)
/dev/hda5 5095 6144 8434093+ 83 Linux
/dev/hda6 6145 6927 6289416 83 Linux
/dev/hda7 6928 6995 546178+ 83 Linux
/dev/hda8 6996 7028 265041 82 Linux swap

I just had a good trial of Ubuntu 5.04 few weeks ago and I found it easier to learn than Red Hat. Now, my intention is to replace Red Hat on my second partition by Ubuntu. I did a little survey on different ubuntu forums and I discovered that this process seldom goes swiftly at once. I have vital information on XP that I don't want to lose and no extra hard disk for backup.

Can somebody help me with a step by step procedure? I am not very familiar with playing around GRUB that I always used or BIOS.

Thanks

This guide's pretty useful:

Generally, though, I'd say you have one too many Linux partitions there--you need really only two--one for /home and one for /
Don't worry. You can delete and resize partitions during the Ubuntu installation process (see above link for details).

Oh, and make sure to install Grub to the MBR.
