Invalid Partition Table?

Okay, so I decided to fully erase all files from my hard drive, so after running the Toshiba wizard, it deleted all previous files, ( but didn't download the files that the laptop came with? ). So when I start to turn the laptop on it gives me the error message invalid partition table, and when I try to insert the recovery disks, nothing changes, it still shows invalid partition table. Is there a way to make the disk load or to make the message disappear?
