Installing Ubuntu v10.04.1 LTS 64-bit

**AaronB** · 09-13-2010

I was installing Ubuntu, and I think I've got myself a problem.

I have Windows 7 installed on my computer. The partitions were setting up as follows:
100 MB for the boot sector
687 GB for drive C:
15 GB for Win7 drive image

This is what I did. I went to "Disk Management" and shrunk the volume for drive C to make a 100GB space for Ubuntu. I left the space "unallocated", rebooted the computer using the disc that I made with the 64-bit version of Ubuntu. I clicked the button to try out Ubuntu. When I got to the desktop, I clicked System > Administration > GParted.

I selected the "non-allocated" 100 GB area to have GParted to partition for Ubuntu.

Here is where my problem is... after partitioning the area. I go to System > Administration > Install Ubuntu 10.04.1 LTS... I follow the prompts and when I get to the step to install to a partition...nothing shows up in the box for what partition I want to install to. So I shut the computer down, take out the Ubuntu disc, and the computer freezes.

I put the disc back in to reboot to Ubuntu, run GParted and instead of seeing all the available partitions... I see 1...yes 1 partition that is 687 GB that is "unallocated".

I'm guessing that Win7 is completely off my computer. What the heck???

How can I get Win7 back??? My computer didn't come with a disc. I guess I'm screwed!!!

What should I do now???

Hi and Welcome !

It's easy to recover Partition Table. If internet connection works fine in Ubuntu LiveCD mode then install testdisk and execute it in Terminal. It will recover Partition Table.

Code:

sudo apt-get update
sudo apt-get install testdisk
sudo testdisk

In case you couldn't install testdisk for any reason, download PartedMagic LiveCD/USB. Testdisk is available in PartedMagic. Boot up from PartedMagic LiveCD and click on Testdisk option in Menu.

Before starting installation again, post partition structure of your Hard disk here. Boot up from Ubuntu LiveCD, open Terminal and execute this

Code:

sudo fdisk -l

Post output here.

* It's small L in fdisk -l.

fdisk doesn't show any partition. Do not try to manually create any new partition now.

Run testdisk on this Hard disk and recover partitions.

Press Alt+F2 and type this

Code:

gksu gedit /etc/apt/sources.list

Above code will open sources.list file in Gedit with root privileges.

Remove # sign before all the lines having universe and multiverse words. Save file and execute apt-get commands again.

Since I'm running from CD...will I be able to save these settings??

it is running in memory, so yes you can save, it just won't be saved when you restart

**AaronB** · 09-13-2010

OK. I'm getting the following menu:

Select a media (use Arrow keys, then press Enter):
Disk /dev/sda - 750 GB / 698 GiB - ATA ST3750528AS
Disk /dev/sr0 - 719 MB / 686 MiB (RO) - Optiarc DVD RW AD-7231S5

[Proceed] [Quit]

I highlight the top one, and get:

Hidden sectors are present.

size 1465149168 sectors
user_max 1465149168 sectors
dco 1465149168 sectors
Device Configuration Overlay (DCO) present.

[Continue]

[Intel ] Intel / PC partition
[EFI GPT] EFI GPT partition map
[Mac ] Apple partition map
[None ] Non partitioned media
[Sun ] Sun Solaris partition
[XBox ] Xbox Partition
[Return ] Return to disk selection

I chose [Intel] and get:

[Analyse]
[Advanced]
[Geometry]
[Options]
[MBR Code]
[Delete]
[Quit]

If I choose [Delete] it asks to write 1's, so I back out with N.

Which option should I choose to recover?
