Hey, I have a problem with my Surface Pro 3. I installed Linux and use dual boot with rEFInd Boot manager. Now I deleted the linux partition and deleted the rEFInd directory from the EFI partition. The problem is, that the rEFInd Boot manager is still there and I am not able to boot from USB to reinstall my Windows 8.1. Is there a way to repartition the EFI partition or reinstall UEFI ? Thanks, Jannis L.
