UEFI changes are not saving. Settings are stuck in one place.

[kunal26das]

I have a laptop with UEFI firmware. I wiped the Hard-Disk of it with bootable partition manager (fill all sectors with zero 0). This lead to my firmware/UEFI to not detect anything at all. Any thing I connect to USB is not detected so I cant re-install any OS. Plus whats worst is that in UEFI settings, any changes I make are not saving. They are stuck the way they were before the wipe. Everytime I select "save settings and restart" I goes back to the way it was. Neither is the "reset to default settings" is working. HELP!!!

You deleted and erased all partitions, including the recovery partition? Most laptops include a method to recover; as an example, my Dell laptop includes a tool to create a factory recovery on an external USB hard disk. My Lenovo is different, but it allowed me to create a recovery DVD.
