Cant boot from external Media

[ShalokShalom]

Hi there

Here is, what i already try, in order to boot from USB/DVD:

Change the Boot Sequence in UEFI
Try to boot with UEFI, CSM and UEFI/CSM
Disable Secure Boot
Hold Shift, while click Restart.
Disable FastBoot

My Media get simply not recognised, while they do their Job on other Devices.

I know, that this might be a Hardware/UEFI (implementation) Issue.

what media are you trying to boot?

 

[ShalokShalom]

Kingston USB Stick and Verbatim DVD. Contains KaOS GNU/Linux with UEFI Support. They work on another Device.

 

[KYHI]

disable secureboot

and use F12 to select the boot device

you may see the Linux usb listed twice - UEFI and CSM

test the boot options and report back

F 12 dont work.

 

[KYHI]

F12 key?
