[all variants] Multi-boot system; HOW TO ERASE ONE OF LINUX PARTITIONS

I have provided a screenshot of my partition layout in gparted.

I currently have one NTFS partition, then a extended which constitutes of 3 LINUX partitions - ubuntu, gnomebuntu and mint 14, then a shared FAT32 storage partition and then a swap par.

For some reason the gnomebuntu partition won't boot up. The second screenshot shows the code that comes up when trying to boot into it.

So, is there a way to remedy this or do I have to erase the partition?

If I have to erase the partition, is there a way to do it that doens't screw up grub?

The last time I erased a Linux partition my systemn wouldn't boot - it wouldn't even boot into a live CD - the HDD was completely broken - I had to run a small distro that loads into RAM and erase the linux partitions.

I also know the MBR overwrite method in windows after which I can erase the Linux par. but then I can't access the other two.

So, can anyone shed light on this? :)
