I have a partition thats unaccessable


OK, This is my first contact with the forum and I am at the very bottom of the learning curve.

I have laptop with 150 GB HD and have already had Unbuntu 6.1 installed on a partition with MS windows on the other part of the partition. After Unbuntu 6.1 was installed I upgraded to 8.1 online and every thing was working OK.

Later I decided to reformat the HD and start with a clean disk, but this time after reinstalling MS windows I went direct to a self written disk of Unbuntu 8.1 for the installation.

Then the problems started.

On the Unbuntu installation I chose a partition of 66% for windows ans 33% for Unbuntu i.e. 99gig for windows and 46gig for Unbuntu.

The installation froze after or during the partition and I am now stuck with 1/3 of the HD inaccessible. I can remember checking the ISO with the check program but not being familiar with the check program Iím not sure if I done it correctly, so the cd could be corrupt.

I have a working MS windows but no working Unbuntu/Linux.

?Can I recover the lost partition or must I start again with a reformatted disk?

With hope DougÖ

not sure about resuming an interrupted install but you CAN reformat the partition without disturbing the windows install

in the ubuntu installer, chose the 'manual' partitioner, and simply edit the existing linux partitions, i believe in ubuntu's installer it would be 'file system options, format as' or something like that.. make sure to re-assign them the appropriate mount points (might have a label left over from the previous attempt to use as a guide)

This does not help, remember I am at the botton of the leaning curve.

Yes the manual option uses the original partitions in place but then if I go forward onto install I'm asked to do somthing with or about the root and non of the options work.

There is no mention of Re-assigning or labels?????

Maybe Ill just go back to winxp at least that works.

I am not sure if I fully understand how that partition is inaccessible. Can you boot into ubuntu? If so, type the following on the command line:

sudo fdisk -l

Ah! well it looks like my partition is not correct, on you sample you have 7 items and on mine I only have 4 and one of those is the one showing the MS winxp.

Its difficult as I have to keep swopping Op systems to see what is happening and then change back to communicate.

I am at this moment down loading another ISO but I have chosen the AMD64 version, I think I will reformat the HD and start again. this will be atleast 8 hours work.

No I cannot install onto the partition. I can run Ubuntu from a cd but can not install. I think the partition is not correct.

Ok, boot with your Ubuntu CD and run the program: gparted - you'll be able to reconfigure
your partitions on the hard drive.

that was just an example

linux should have a minimum of 2 partitions (/ and swap), idealy at least 3, /boot, /, and swap
windows needs 1
so 4 is fine
size the windows partition to what you want it to be
put about 100 megs as /boot
swap is a gray area, though i would use the swap to be as close to the amount of physical ram you have as you can afford
the rest should go to /
unless you want a separate partition for /home (the advantage of this is if you have to torch and reinstall your linux you can re-use your /home partition without formatting it, thus keeping all your files)

Did you first install a clean version Windows, and started afterwards with the Ubuntu installation? Is that correct?

I just wonder how you came to play around the partition sizes when Windows was already installed. Does the Ubuntu installer have an integrated re-partitioning tool integrated, something like GParted?

Running a LiveCD will at least shed some light on the contents of the disk.

Yes, reformat HD,
Install Winxp,
Use Ubuntu cd,
Partitioning starts from Ubuntu cd,
partitioning stops/crashes??
forced to power down.
Winxp still working on allocated partition but Ubuntu refuses to install on allocated partition,

Ubuntu does have Gparted in the live cd. Also there is nothing wrong with installing Ubuntu after clean install of windows.
The problem could be defective cd media or some missing files. If can boot but not complete the install then first thing to do should be try and start the installation process again.
Continually failing installation process can mean corrupt media.
I hope you are able to boot into Windows.
Use ubuntu live cd to recover the partitions. Else you can download other partitioning tools if you do not prefer Gparted.
