Were you messing around with a new boot manager or fiddling grub? The
*bad* partition IDs look suspiciously like the hidden versions of
regular IDs. At least 0x93 is hidden 0x82. 0x15 doesn't really match
teh hideen version of anything sane. For instance, 0x05 is a dos
extended partition for old small drives, and probably not what you had
originally.
You _might_ try changing 0x15 to what you know it should be. 0x0F
perhaps. On the other hand, that could whack what's left of your
drive. Continents could slide into the sea. Winged monkeys could
fly from you posterior. You get the idea. Try this WAG at your
own risk. It is just a _WAG_.
Here's a list of partition IDs in case you don't have one handy:
