Hi all, I got my S3 a month ago. It came with W8.1 pre installed. After MS released W10 I successfully upgraded to W10. Now I want to clean install W10 from USB media. Followed this guide http://answers.microsoft.com/en-us/...urface-3/73b1b864-da90-4b40-9138-2f7ca90ca43e but my Surface 3 couldn't able to boot from USB drive, had tried with 02 different USB drive (with both MediaCreationToolx64 and rufus). However, it did boot from USB (created with MCTx64) if I go to Settings - Update & Security - Recovery - Advanced Startup - Boot from a disk (ex: USB or DVD) or device (UEFI only), and this is the only way to clean install W10 on my Surface 3. Is my Surface 3 UEFI firmware have problem?
