Secure boot Vialation

[Philsavspurs]

HP All in one 24 - FOxx

Model = 24-f0014na

Bios = 84DE F.10

System ID 84DE

Product ID = 4FT17EA#ABU

Hello all A family member has asked me to look into his HP that's not now booting into windows, when it's first turned on we get a msg saying " Secure boot Violation  Invalid signature detected check boot police".

I've gone into the bios and changed all the boot settings for secure boot control, turning them off or on but still not getting anything booting into windows, this only gave me either a blank screen or an HP logo,

I tried a MS restore which told me that windows 11 had been installed onto the system at some point but with no option to return to Win 10 (older than 10 days I'm guessing)  but this didn't even fix anything.

I have also run all the HP test's within the help system which all passed ok.

Is there a bios update that can be done?  is this PC even windows 11 compatible?

Any help from anyone would be very much appreciated

Many thanks

Phil

For windows 11, nothing here and probably won't change the problem see under windows 10

it's up to you, if it goes wrong, the computer can become completely unusable

is this PC even windows 11 compatible?
