Hi,
Also check the USB Key Drive BBS and Hard disk Drive BBS...
The Legacy USB Support is in reference to USB 2.0 on or off, and is not related to which type of Bios..
You do not have a WindowsBootManager in the list on image 2 or 3...
The EFI Folder on the Root may serve the same purpose, but the only place I have ever seen one is on Installation media...
Windows Boot Manager is mandatory for booting into UEFI Bios... That is the Boot Device, and is only hardware related due to it's location..
The UEFI: i Key Encryption Disk 8.01 is one option, but there is also a "LaCie itsakey 0.00"... That may be the one you want...
When your computer was working, did you see the Windows screen with spinning dots when you booted or restarted.... Or just the manufacturer's screen with spinning dots... then the logon screen ?
