Question Reboot doesn't work properly / F12 black screen ?

[Patrick797]

Hi everyone,

I have a custom-built PC running both openSUSE Tumbleweed and Windows 11.

I'm experiencing an issue when trying to restart from openSUSE into Windows 11. Upon restarting, I don't see the usual boot screen that shows the F12: Boot Menu and Del: BIOS Setup options. Instead, the system immediately boots into openSUSE without showing it's boot menu either.

If I press F12 before openSUSE starts loading, I just get a black screen and nothing happens.

However, if I shut down the PC completely and after a few seconds power it back on, I do see the expected screen with the F12 and Del options.

I've checked the BIOS settings, and everything appears to be in order.

So my question is: Why doesn't the boot menu screen appear after a restart, but does appear after a full shutdown and cold boot?

Any help or insights would be appreciated!
