Yes, you need to install it internally, you cannot boot Windows from a USB connected drive.
Pretty sure that was never possible. You can boot to a USB flash drive or optical drive if it contains an installation disk or a Linux OS, but not a Windows OS. Same for BIOS and UEFI.Also, I thought a Windows OS could be booted off a USB drive, was that only in pre-UEFI?
You will probably get better answers to that than I can give. My only attempt to install (a Linux distribution) on a UEFI system resulted in a complete mess. I stumbled around for a few days before finally installing (Windows 8) "fresh." And I don't remember the exact symptoms of the problems nor what actually got me going again. If you need Windows 10 installation media I think that you can get the .iso from this Microsoft site. During the installation the Product Key will be obtained from a chip embedded in the motherboard.Do you know how I would build a USB flash drive to get my boot stuff back in order to boot from the Windows system on my internal 32GB SSD?
Yes, the older BIOS and the newer UEFI are firmware "flashed" to the motherboard. They, as I'm sure you already know, provide the user interface that allows us to see and change certain options in the hardware (such as boot order).I thought they were in flash on the mother board but never really thought about it.
Acronis works VERY well however you cannot ask it to do something that is not possible [boot windows from a usb] No windows operating system will ever boot from a usb drive; not going to happen. You can however boot linux from a usb drive [or optical drive for that matter]Because the Acronis software had not worked and had felt like a very old design
What the OP did was download and build a W10 USB system, that can be booted from and then used to install or repair his windows system that is on the SSD in his system. He repaired it.You're welcome.
But I don't understand what you did. What's this "Windows image"? I make a backup image of my system periodically, but I doubt that you mean this kind of image.
OP = Original Poster (you)I do believe that's what I did. What's an OP?
Thanks
