Bricked after installing PK and enabling secure boot

[sz3bbyla]

I lost hdmi and dp output. computer start and there is no output on display. also is no booting

I try to reinstall windows and when I set install platform key computer not start anymore and no video output
there is any chance to restore bios ????

Why were you trying to install platform keys and not using a normal installation of Windows?

Sounds like you may need to remove the SSD and place it as a slave into another PC, wipe the disk, and reinstall from scratch?

Seems like this is a KNOWN Intel error (see the forum post where an Intel employee got the same error).

Pinning this to increase visibility as I suspect many people will try to enable secure boot in order to install Windows 11.

either you have warranty and RMA if possible

i wonder where is the key stored at, if is in TPM/fTPM SPI flash bios does not change much

unless we can have a ROM version that patch the secure boot option default as false
then SPI flash the rom chip to unbrick.

I just upgraded Windows 10 to Windows 11 without any workarounds.

It seems that secure boot only needs to be supported but does not need not be turned on.
