DVD installation media is fine.
Building the USB thumb drive installation media from the link I posted, is also fine, and free.
You can use the product key that you have for the DVD... it's all the same.
Now that we know you have an MSI motherboard... the F key for the Boot Menu is F11, not F8.
IF for some reason, you don't SEE your external DVD drive, or a USB stick, on the Boot Menu... MSI has a utility for that too.
It's called the MSI Smart Tool, and can be found here...

My apologies for earlier saying that F8 was the Boot Menu key. I should have googled "ASUS Bazooka B350M" before posting. Because when you google that, you find out there is no ASUS Bazooka B350M.
It's actually an MSI B350M Bazooka.
