I found this using google...

Q: Why do I get 'Invalid partition table signature' warning message?

A: There is a two bytes long identification signature at the end of the partition table. This warning can happen in case of a brand new harddisk or a damaged partition table. Running aefdisk with the /mbr command will fix the problem.

and here a links to help you....

Thanks for the link....

The one thing that is freaking me out the most is I can't seem to get to DOS. I'm not worried about any files if I have to wipe the hard drive then fine, but I can't figure out how!!!!! It's a laptop so no floppy, however I do have a usb one. No matter what I seem to try whenever I try and boot up the toshiba logo appears and then i get a black screen w/ invalid partition table.
