Windows 10: Renewed motherboard from amazon, no option to choose MS version booting off Microsoft USB...

Renewed motherboard from amazon, no option to choose MS version booting off Microsoft USB stick. Auto chooses Home and activates. Want to choose pro, but can't.I want to use my pro key when I install winodws , but do not get the option. I'm guessing somehow I got an embedded key in motherboard? Its just an MSI 460m pro -a. I thought only vendors can embed keys, so maybe its from a prebuilt system? I did NOT sign in with a microsoft account and it still was activated home oemdp. This is a new system. New "renewed " msi board from aamzon. New SSD, with a New original USB image of windows .Is t

Booting from USB on x38 Motherboard, NOT?

See sys specs... ASUS ROG x38 motherboard, flashed to x48 Rampage.

In BIOS under "Boot Device Priority", I select and of the 3 boot device slots, and no where do I find an option for USB, these are the only options in each:

• 1st floopy drive
• HDD: P0-WDC WD2500KS
• ATAPI CD-ROM
• Disabled

Is there a place in the BIOS to enable boot from USB?

It's AMI, says v02.61 on the BIOS screen
