unable to reach bios via USB ports

[vlknkzr]

Hello,

when I was trying to install windows to my new desktop unit,

I created an windows installing USB stick.

but it didn't start from USB, one of youtube channel suggested change USB security to booting. So I changed all security of all USB ports on BIOS. now no one USB ports working. I get keyboard error and no USB port sees keyboard.

I took off the BIOS battery for 10 minutes. Then started again system, there was an alert from start: CMOS will reset if hit ENTER. I cant hit enter because USB not working.

so BIOS reset from battery didn't work.

Could you please help?

hi

sorry, you seem to have made a serious misunderstanding, and/or watched the wrong video..
you do not have much possibility, you should try, a reset of the motherboard, with the jumpers, but hp, no longer delivers this information for many models

try with the CMOS battery again, but if not tested, with the computer unplugged

if not, it will be necessary to find how with the card jumpers, but I don't think I can help with that
it will either be necessary to find on the net, or go to a specialist
