I purchased x86j4105 products. (emmc + pre-installed windows 10)
I removed Windows 10 on emmc
Instead, I installed Windows on sata ssd.
However, it was not automatically authenticated as expected,
I reinstalled to emmc using the backup image in wiki.
After that, I checked whether it was certified or not, and it said that it could not be certified.
The simplest way to reinstall Windows 10 is through Windows itself. Click âStart > Settings > Update & security > Recoveryâ and then choose âGet startedâ under âReset this PCâ . A full reinstall wipes your entire drive, so select âRemove everythingâ to ensure a clean reinstall is performed.
