Hi Kai,
Got it, thanks. Now, in your BIOS screenshot, I've looked at the Boot Order & the USB drive is already on top of the list, which means you've already set it as the primary boot.
With that, it's either your USB is having a hardware issue or the installation media was either not configured properly or corrupted.
Kindly follow & complete these steps below. If all fails, I recommend replacing a new USB hardware to proceed.
- Kindly follow the "Media Creation Tool" steps from the link below & see if you're able to boot from the USB.

- If that won't work, then follow the "Rufus tool" option shown on the same link above.
- If that fails, repeat the "Rufus tool" process but changing step 9 Partition scheme to "MBR" instead.
I hope this helps. Let me know how you go. Thank you!
