Can anyone offer any advice as to why the BCD registry would repeatedly get corrupted?

 

Notebook works fine for a while but then displays the Boot Device not found error on startup. Restarting again presents you with a select keyboard layout screen & then just the options to advanced troubleshoot or turn off. Selecting the boot to UEFI settings option allows access to the BIOS on subsequent restart & hard drive is listed as connected.

 

The only way I have managed to get round this is to reboot & enter command prompt mode, followed by using diskpart to assign a drive letter to the system boot (UEFI) drive. By then deleting & recreating the BCD registry in \EFI\Microsoft\Boot, access can then be recovered on reboot.

 

Have scanned for malware to no avail and now out of ideas - any help appreciated.

Thanks for response but hard drive appears fine and, as stated, is always shown as available when booting into BIOS.
