Installed OS in UEFI mode in AHCI configuration. After updating the BIOS, system failed to boot into OS. The "UEFI:Windows Boot Manager" is disabled from boot priority selection. Is there a new BIOS which solves this issue? How can I save my OS?
In BIOS->BOOT section, please go to "UEFI Boot Drive BBS Priority". Select "UEFI:hard drive". Save and exit BIOS.
Press "F11" key and select from "UEFI:hard drive". It will boot into Windows OS.
If you go to BIOS->Boot section. The "UEFI:Windows Boot Manager" will show up.
