Unbranded Tablet AMI BIOS does not list boot options

Solution 1:

I made image with Macrium from an exact copy of the unbranded tablet. I have numerous of these tablets in both Win 8.1 (Bing) and several I upgraded to Win 10 years ago.

My particular tablet had issues after I tried to upgrade to win 10 lately, as all my drivers didn’t upgrade like they did years ago. Probably because windows doesn’t support upgrades for old Bing machines. Anyway no drivers meant no touchscreen, or sound, or windows screen button etc. I spent a long time trying to update drivers but things like touchscreens hardware would not even show up to add driver.

So It dawned on me to just image one of my working Win 10 unbranded tablets. I used Macrium Resolve Free and copied the image from the drive of one of the tablets currently running Win 10 onto an SD card and used used a cheap USB stick to load Macrium's bootable rescue USB, configured my image through restore in Macrium, and then booted the tablet and entered the restore sequence. The restore took over and in 20 minutes or so, my tablet was a mirror of the one that worked fine. It even activated since the activation code is on the motherboards bios. All worked well....problems all solved. Try it.
