partitioning - Trying to recover deleted Ubuntu partition

I made a mistake in logging into my 200 GB Ubuntu partition. I could not access Grub after that. Using a live CD I then ran Boot_Repair and apparently deleted the partition, I guess because I ran it from my 70 GB Windows partition. I can send the results of boot_info before that and of Boot_Repair. Then I ran TestDisk, which apparently only found dev/sda/ -320GB / 298 / GiB - WDC - WD3200BEVT-22A23T0.



Was there any more I could have done with TestDisk? I looked at the TestDisk_Step_By_Step example and found no way forward given that no other partitions turned up



I have run gpart and found this:



/sda1 - 15 GB
/sda2 - system reserved
/sda3 - 70.15 GB

/sda4 - extended 212.84
unallocated - 209.10
/sda5 - unknown 3.74 .


I have been told I can recover the partition using gparted's Rescue start end command, but I don't know what to enter for start and end.



EDIT: TestDisk Deeper Search stated that "the following partitions can't be recovered" and listed a 220-GB Linux partition 6 times. Then it stated that "The current number of heads per cylinder is 255 but the correct value may be 128" and I could try to change it in the Geometry menu (because apparently these are overlapping partitions)
So should I do that?
