Question Motherboard (ASUS Z97-A) refuses to boot Window but boots Linux just fine

[hafsblau]

Hi, I have an ASUS Z97-A + i7 4790k which boots into BIOS and boots Ubuntu from a USB just fine, but when i try to boot Windows 10 from the same USB and the same USB port, no image comes up and it boot loops. Here is a video which shows what screen it gets stuck on:

I have tried changing RAM, clearing CMOS (including removing the battery), changing USB port, changing CPU. The Windows USB works when I try it on another PC.

Does anyone have an idea what could be causing it?

Thanks.

EDIT:
Correction, I got something wrong in the OP, the problem is actually the processor (i7 4790k). My i5 4690k boots both Windows and Linux but my 4790k is only able to boot Linux. (Same mobo, ram, usb, etc).

I made the flash drive with the official media creation tool for Windows 10. I also have another USB with Windows 11. Both work in my main PC and work on 4690k, but neither works on the 4790k.

Blinking cursor=BOOT files not found. Check BIOS settings for CSM/UEFI option to match what installation USB is made for, one or the other.

See my edit, I was wrong when I said the motherboard was the problem, it actually boots Windows fine when I use my i5 4690k. It does not boot windows when I use my i7 4790k, everything else being identical. It seems to me this should also exclude any CSM/UEFI option issue, right?

It should still match, UEFI is preferable.

Ok, I changed CSM setting from auto, and tried booting from the "USB [UEFI]" instead of the "USB" entry, it didn't make a difference except that it hangs on the motherboard brand logo instead (Asus).

However, I also tried various other settings and found that if I change "active CPU cores" down to 1, it is able to boot to the Windows Installation medium. Any ideas?

What bios version do you have; final 3503 beta? 2801?

3503

Also, I just got hold of a different 1150 motherboard and tested the CPUs, with the same result (can only boot Windows with 1 active core). So it seems like there is an issue with the 4790k processor.
