can't access bios to boot from usb

Hello,
so i have my laptop on windows 8 and i wanted to clean install windows 10 to it

i had no way of enter bios/uefi or boot menu for usb booting since it's not in advanced start up
and i tried every single key while booting f1-f2-f11-f12-del etc

so i had an idea (btw it's an old laptop i never usually use it) to just upgrade to windows 10 and then i'll have bios access to do my clean install but i forgot my admin account pass and i'm stuck on local acc with win 10 on a flash with no way of booting from it

any help thanks
 


i know which button it's DEL and i did it before but never with win 8 it's never worked with 8
