1. Updated from 7 to 10, then wanted to do a clean install 2. Downloaded ISO from windows utility (wouldn't recognize my Sandisk Cruzer flash drive) 3. Used Rufus to apply ISO to flash drive 4. Installed Windows 10 like I would any other OS (delete all partitions on C, let it do it's thing, automatic restart, remove USB, but no boot) BIOS sees my SSD. Boot order is correct. Startup repair didn't help. "Resetting this PC" repair option didn't help. Tried it 5x times and always get "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key". Any ideas?
