csm

For some reason, I can't boot from my SSD which has Windows installed on it unless I have CSM enabled in my motherboard's UEFI settings. I believe this is preventing secure boot from enabling properly, which is preventing me from updating to Windows 11 due to the secure boot requirement. I'd...

I can only boot into Windows 11 if I have CSM (Legacy Boot) on, otherwise I get a hanging black screen. Also if I have CSM on - I can boot into BIOS, however iGPU is inaccessible! I would rather have a UEFI boot, but as stated, if I set it to that ¹I can't boot into Windows, and ²I can't...

Some 300 series motherboards don't even include or mention Windows 7 or 8.1 on their support pages, and installing Win7 requires some fooling around with USB drivers and other stuff... Same for recent AMD mobos... So how long until new motherboards completely strip away any legacy OS support...
