Deletes all partition data from the Intel partition table only (by filling it with zero bytes). Both the MBR code and the signature bytes (if any) remain the same.
Some BIOS use the partition table content to set the harddisk geometry. Unexpected values can trigger some BIOS bugs. The DOS version of TestDisk is the most affected. If it detects a known bug, it displays Buggy BIOS after the disk geometry. Delete may solve the problem. Reboot your computer and autodetect your hard disk.
