Installer hangs at "starting udev"

When I try to install OpenSUSE on my desktop, It freezes at “starting udev”. After 60 seconds or so, my desktop automatically resets.
I tried the “check media” option, but there it hangs at “starting udev” aswell.

So then I tried it on my laptop, and “media check” worked, no errors, the installer works, everything works fine on my laptop.
So I tried to update my desktops’ BIOS, no avail.

Maybe this is a hardware compatibility issue? Here are my specs:

  • ASUS SABERTOOTH 990FX R2.0
  • AMD FX-8350
  • Kingston HyperX Fury 8GB
  • NVIDIA GTX 970

Thanks in advance!

Nevermind, I fixed it by unpluggin my external HDD.
I have no idea why that caused issues.
