Hello everyone.

Since I updated to Windows 10, I can't access my BIOS anymore.
What I did:

- Press "Del"-Key repeatedly or hold it while boot (this is the key I enter my UEFI normally).
- Disable Fast-Boot to increase time to press the button - doens't work.
- Hold Shift when pressing restart to enter the troubleshooting screen (same is done by going into "Recovery", then do an "Advanced Startup"). Then Advanced Settings - there is no UEFI Firmware Settings for me?!
- CMOS Reset by moving the Jumper (Power down, PSU Switch to 0, Cable off, Move Jumper for 20s, move back, power on). PC just starts normally and I can't enter the BIOS.
- CLR_CMOS button on the back of my motherboard. PC starts normally (same with Jumper).
- BIOS_Switch button on motherboard - doesn't have any effect. The manual indicates that one LED should light up to show which BIOS is used - no LED lights up.
- Removed the HDD and booted, I just enter a black screen which sais that I should connect a propre Boot device and press a key to startup or change boot order (which I obviously can't if I can't access BIOS).

PC is connected to a normal DVI Monitor (tried it with a VGA as well). Motherboard is a Maximus IV Extreme, OS is Windows 10.
