    USB booting issues.


    Had this problem about a year or so ago. Also had so many issues with 10 I had to go back to 7 to complete some important research and projects. Went back to 10 a few months ago and have it running very well now except for an important issue. I use Casper 10 to create my bootable backup copies of the primary drive. In the event the primary crashes (which happens often due to the experiments I may be conducting), I can boot to the backup and be up and running again in seconds. This just is not the case with windows 10. I create the bootable backup but when booting to it, I get the "inaccessible boot device" blue screen. Casper support has been great at their attempts to get this resolved but we have all ran into a dead end. We did arrive at a somewhat less than desired workaround. The bootable usb3 backup will not boot but I can copy it to an internal hard drive and the internal hard drive boots perfectly. In stead of seconds to be back in operation it takes considerably longer this way. I firmly feel that for some reason windows 10 is blocking the usb3 booting. Looking for suggestions as to what to look for!

    A basic problem with USB 3.0 is the drivers for it are not in the BIOS while USB 2.0 is supported. The loading of the OS brings support for USB 3.0. Some computers have combo USB 2 and USB 3 ports and may get booting support. Also involved is MBR or GPT/UEFI boot devices.

    Won't boot off usb2 either. Gotta be a way - just have not figured it out yet! This was one of the reason I went back to 7 as it had no booting issues with usb.

    It's certainly possible for Win10 to boot from USB - it's actually a feature called Windows to Go, which is available on volume-licensed versions of Windows and via some 3rd-party tools like WinToUsb.

    When you are booting from USB is your old drive still connected? It looks like one of the things WtG does is disable access to internal drives.
