I have win 8.1 pro x64 from an ISO install on my system and need to wipe my HD because of super long boot-up problem. Went into BIOS to set to boot from USB and the only option I see is "USB Entry for Windows to Go". I don't remember this being a setting there before and this is the only USB option. BIOS is is Insyde 3.7 and updated to v.1.4 (no prpblems). I'm curious if this right as I have been having problems booting from USB with DBAN to clean my HD. Any help would be appreciated. --Also sideline question when mounting DBAN iso w/ Rufus can I create a bootable ISO w/ this prog on an UEFI only system.
