I did a full wipe and fresh install using Roofus and the Windows 10 ISO after having updated to register my keys on the MS site. I find now that unless I use Roofus, there is no way to boot off of a USB. Before I was able to take the SP3 restore files and put them on a fat32 usb key and boot into that to fix. Now that 10 is on, I get errors about UEFI file corrupt or missing. I have also tried making a restore key from within windows 10 to be able to do restores where the drive is hosed and this has the same error. Seems only thing I can do is use the ISO's from MS and Roofus to create a bootable USB. Anyone else experiencing this?
