Bios not showing, Black screen GPU

[33Fraise33]

Hello everybody,

I got a little BIG problem! I was planning to start over with my rig. So i wipped al my drives etc. And then i opted for default values in my bios : BAD choice i guess. The make the picture for you guys : i have a sabertooth Z87 equipped with a gtx770 and a i5-4670k. The problem is i only have a dvi monitor so i only can connect to my GPU not my igpu (on my mobo) because i don't have a monitor equiped with hdmi and display port.

The problem is now: the default values in my bios set to use my igpu and not my gpu with my screen connected. So when i start my computer i can't access the bios AND i can't boot (no bootable drives).

Please help me what do i do now? i'm really desperate i have already tried the cmos jumper and battery method to reset bios but no luck.

i would buy an hdmi or displayport to dvi adapter and plug it in to your igpu port and boot it up that way.

Or try to do it blindly with a little help from youtube tutorials

I might suggest getting an adapter for your cable, in that case. They're not that expensive. And yeah, maybe try out what Barelsh recommended.

 

We can do this! C'mon! Let's do it!

Maybe hold DEL for like... A full minute, then press F5? Then enter for yes? I'm not exactly familiar with the Sabertooth Z87 UEFI.
