Why does partition table corruption even happen?

I created an extended partition and tried to add two NTFS units to it. Instead two 125 GB partitions, I got – according to Disk Utility – 2 X 982 GB partitions plus a 14574534 TB one (wahey!). I don't remember to have done anything weird.

The case is:

Neither Disk Utility, GParted or fdisk will let me fix/delete the extended partition, and in addition,

My LiveCD won't boot, although the BIOS order is correct and it worked perfectly before Ubuntu was installed. The hard drive installation of Ubuntu will start instead (edit – I got it to boot but having the drive unmounted does not fix the issue).

I guess I could try even more tools but I don't think this is that much of an unusual problem... what's the straight-forward solution for this?

Thank you in advance.

Okay so I managed to fix this, but in a pretty heterodox way I think.

As I said, my problem in particular consisted in an extended, infinisized-yet-empty, useless partition that couldn't be deleted with any of the usually recommended GNU tools for these cases.

It could be deleted with the Windows 7 installer. However, this messes up the whole partition table so you need to recover it using testdisk (no, I couldn't do this before the delete).

After this, you need to recover your GRUB with a CD or so.

I hope this helps someone in the future.
