Rebuild MBR

Select Rebuild MBR on Operations menu or press F7 key.
Use this function to manually rebuild the master boot code (located on cylinder 0, head 0 and sector 1) when it was destroyed and the computer couldn't boot from it.
Note: This function only rebuild main boot code in the master boot record. If you want to recover partition, you can use "Restore Partition Table" or "Rebuild Partition Table"
