I have a 160 GB disk with 80GB of it used (mainly Mint, with a 15 GB partition with openSuse, used for experimenting). I've decided to use the extra 80 GB for XP, and tried to install it today. I've tried to use the XP's setup to format the unallocated 80 GB as NTFS, but after the format there was an error, saying something like 'unusable disk'.
It wasn't a pleasant message to receive, but since I don't need windows at the moment, I've decided to leave it alone, and maybe in the future create the partition for windows in advanced, using GParted, and try again. I've used the live CD to repair the grub, and boot into my Mint.
I've used the partition editor in Mint to try and see what's wrong with the 80 GB partition, and then I was terrified to find out that I have no partitions, and all of my disk is unallocated.
What happened to my partitions? How come I have no partitions but a working Mint OS? How can I save my disk/data/os?
