Can't Get Boot to BIOS

i have a acer desktop ,and it its set tofast boot i can still get in ,i just have to start hitting the DEL key before i hit the power button,when in there i then turn on the F12 boot function key (just to have the different bot option )thats turned off in a lot of bios's now

Hey guys... THANKS to all of you who have offered suggestions/help/etc!!!!!

Let's see... one said "system not verified". True... it's a friend's system and he screwed up "his first try" for Win10... so I restored back to factory... which was Win7. Doubt if he ran a Win10 test.

He then downloaded Win10 again... and that's where he ran into "black screen"... which I found the 2nd video card... google's, found several suggestions, FLAG+P and (blindly) down-arrow/Enter returned the video back (think I set it to dual-monitors??) Anyway... point to BIOS was to disable the onboard video...

Responding to the pictures... I've gotten into those screens... BUT... it does NOT come up with "UEFI" choice... can't see THAT screen right now (returned PC a bit ago) but it had something to do with "additional troubleshooting" which only wanted to run me towards SYSTEM RESET, more troubleshooting or power down.

Anyway, still looking for a way to get into this/any PCs BIOS... so I can help him next time. I have a Win10 laptop in garage... I'll pull that out tomorrow and see if IT will produce that UEFI choice. Of course, if it does... and his doesn't... then I'm really screwed.

Thanks again!!! Any/ALL help is truly appreciated on my end!!

If you can't get into Windows at all to do what I suggested above try this. Power down and unplug the power supply from the wall outlet. If it's a laptop remove the battery. Now press and hold the power button for say 10 seconds. That will drain any residual power and take it out of any sleep or hibernate mode it may have been in. Now plug the power supply in and boot up while pressing what ever key is required to get into the BIOS. This procedure should boot you up from a cold start and get you BIOS access.

This worked for me, thank you

I read somewhere that Windows 10 shuts down to a Standby mode - from which you cannot get to the BIOS (as it is permanently in Windows). To get around this, I push the on/off switch for 5+ seconds until the machine shuts right down, then when it is turned on it starts from the BIOS and the BIOS can now be entered by hitting the appropriate button/s.
