Changing Boot Order To Usb Blind

[ak6786]

I need to change the boot order to usb so I can reinstall windows. Because I can't see and my screen reader needs windows to run, I can't access the bios.
Can anyone tell me how many times I have to press the arrow keys and when to press the enter key? please list all keys I have to press since I will have to do this without any site what so ever.
thanks

Download a copy of "PLOP" and burn it to a CD, use it to boot into a USB stick!.

I do have it on a USB stick but I need to change the bios settings so that I can go to my USB rather than my hard drive when computer restarts

Hi ak6786,

the idea behind my thinking is that you have PLOP on a CD and W10 on a USB, that way you can force boot from a USB stick!.
