PC not displaying option to boot into BIOS and won't boot from USB install media?

[PapaShand]

Hi, My computer when launched will not give me the option to boot into BIOS and even when i press the correct key to boot BIOS it still does not launch.

I purchased a Windows 10 Product Key, made a bootable flash drive and was going to install it. But i removed my other HDD with windows 8.1 and plugged the flash drive in and it comes up with error 0xc000000f saying it will not launch because it cannot access Windows files. However, i don't want windows 8.1 and just want to clean install windows 10 on a new HDD. How do i get it to boot from usb and not give me the error code so i can clean install windows 10 and have rid of my junky old HDD and windows 8.1? Thanks.

press f2 or delete fast. like really fast. (press power and hold it down). If that dont work clear cmos. It will change BIOS to default settings. Letting you get into BIOS , letting you change the boot order

Thanks. This booted me into BIOS, i then selected boot from no other than USB but when i save and exit computer restarts as it should but it comes up with wondows 8.1 logo instead of booting via the usb. Do you know how to fix this? Thanks.

Cant remember exactly. Does Win10 usb install require UEFI bios, if so do you have that? Did you get win10 from microsofts website where it asks you to put in a usb drive and downloads & loads the win10 install onto the drive automatically?
