Gigabyte brought encapsulated BIOS in 01/2022 for security reasons and this might the reason you need a new @BIOS...but I also would prefer getting a USB stick...Hey everyone,
I have a 5950X and a 3090 Strix. I don't actually have a USB stick here (heh...) and always used @BIOS. But @BIOS isn't working any longer - it keeps saying I have to update the app itself, before I can update my bios which I found strange.
I googled this and folks are just saying "don't use @BIOS". Will try what @Medizinmann wrote above and see.
Well could it be you still use MBR on your boot drive?EDIT: To enable Secure Boot (either Custom or Standard) I had to disable CMS under BIOS. When I do this, my PC will only boot to BIOS - it cannot boot to Windows unless I revert this. Any ideas what I have done wrong? Seems without CMS enabled it doesn't recognize my boot drive?
If this is the case you need to convert it to GPT!

Use MBR2GPT.EXE to convert a disk from the Master Boot Record (MBR) to the GUID Partition Table (GPT) partition style without modifying or deleting data on the disk.
