I have tried my desktop, and it gave me blank black screen...
And disabling secure boot will brick your windows, if you installed using it. So to use your windows, you will have to re-enable it. It is not interchangeable.
As for the laptop, black screens all around.
My previous laptop (Acer Predator Helios 16 2023) did have secure boot on, but it had to be turned off for virtualization and dual boot (the one that 'lost the harddrive' between each enabling of secure boot).
My new laptop (ThinkPad T14s) does in fact not have it enabled, warranty deep into 2027, and I am not even sure how the OEM or Retail OS is installed or re-installed. Further more, it might also 'lose the harddrive' like my previous laptop, making it impossible to use install media.
P.S. I am an programmer, and I have to test my solutions on different OS' and applications. So, atleast for me, backing-up my work and re-installing an OS will take a rather long time.
Also... I wouldn't be able to attend any more LAN parties.
