I have an aspire switch 10, it crashed when i wanted to upgrade from windows 8.1 to windows 10.

Now it says error code:0xc0000225, I have the USB media recovery from acer store.

I have enabled f12 and have raised USB HDD to number 1, but when it gets to f12 boot, the only option is windows boot manager.

I want to boot from USB but the option that comes up is windows boot manager, how do i change it to boot from USB???.

thank you...
