Installing Ubuntu 11.10 after failing

[spa21788]

Hello,

I carelessly deleted my ubuntu partition (80gb approx) on my laptop, which is dual booted for ubuntu 10 and windows 7, because I deleted the partition my boot loader doesn't work.

I put ubuntu 11.10 on my memory stick and attempted an install, I was warned that if I didn't have 2.4gb on each partition the installion might fail, which it did, now when I try to re-install it brings me to the partition table, which I cannot understand :(

I was hoping someone could explain the steps I need to take to fix my stupid mistake!

Attached are some screens to hopefully help in the process.

Thanks in advance.

You may be able to save the existing install with TestDisk.

Testdisk can be run in ubuntu live mode.

Shrink the large NTFS partition (/dev/sda3) untill there is enough room to expand one of the ext4 partitions to the size required for Ubuntu, then use it (the ext4 partition you chose to expand) as a / (root) partition.
