I currently have a dual boot system with 6 partitions on my 180GB hard disk (4 NTFS, 1 for swap and the other one ext4). Ive got WIndows 7 and Ubuntu 11.04 (upgraded from 10.10) installed.
The 11.04 installation is messed up right now: missing dependencies/ 2 fglrx installs/ i have to manually mount every drive in order to use it/plymouth extremely messed up... Anyway I spent hours and hours fixing stuff or making them worse.
I now prefer to do a clean natty install. The problem arose: The installer sees my hard drive as 180GB of unallocated space. It doesnt detect any partitions, any other OSs and my only option is to format my whole drive, but I cant do that with all the important files and such.
Is there some way I can just format the current Ubuntu partition and install Natty there? (causing the installer to properly see Windows partitions for dual boot of course)?
Heres a pic:
Update! : I played around with parted in the terminal and tried to use its print command. Heres what I got:
Error: /dev/sr0: unrecognised disk label I dont really know if its useful or something, Im just trying stuff.
BUMP? I have some more information. When using Disk Utikity from the LIVECD it does see my partitions!!! :OOO But strangely enough it does see two more unallocated spaces: one of 43GB and... i laugh every time I think of this.... and another 18 milion Terrabites of unallocated space. Clearly my HDD is messed up so I decided to delete at least one partition that I do not plan on using.(I thought maybe that a change in the physical drive will update the partition table or something) Another problem: That did not work and it gave me the following error: "Cant have overlapping partitions." I googled this and it looks like a very bad thing.... Like I might have to completely reformat my drive... And I most certainly do not want that...

The fdisk -l command wont do anything, I suppose it needs some parameters. Yes I cand boot into the other two OSs fine, I did try a check disk, and it did not solve anything.
EDIT: Stupid me, i didnt use sudo. Here are the results from sudo fdisk -l:

Ok I found something RAID related and I executed this command: sudo dmraid -E -r /dev/sda just to get this output: "no raid disks and with names: "/dev/sda" "
