Reply To: raw partition
If you’re fortunate, all that happened is the type byte in the partition table was corrupted. My suggestion would be to run GPartEd (GNOME partition editor). It is available in many Linux distributions, but it is also available as a Debian bootable image (which you can write to a CD, USB flash drive, or even PXE boot (although I suppose that is sort of for über geeks)).
In any case, you may wish to use drive cloner software first, so that if nothing else, you can get back to how you are right now should you mess something up (worse?) with what you try. My suggestion would be Clonezilla; it’s free/open source, and has worked fairly well for me.
