Lost MBR on disk

trying to recover a lost partition table, where the signature (0x55AA) has been lost, though attempting to restore using a number of tools (fdisk, testdisk et al) the write fails.

also the os is unable to read the disk geometry correctly, after attempting to correct the geometry, the updated geometry fails to save.

im lost as to how to get this rebuilt partition table to save.
