I just bougth Ezpad 6 and i am trying to format and install Windows 10 version 64 bits . I tried to compile to usb pen via: Rufus and WinReducer both don’t work, first it gave me an error with driver UEFI and second doesn’t reconigze my usb. I boot from Boot Manager menu.
With disk management i check there is hidden partition with restore image perhaps i can’t install any Windows version.
Backup your drivers via dism or double driver first.
Maybe make a full backup with latest acronis winPE.
Then download an original win10 x64 iso form Microsoft’s website and burn a USB drive with it with Rufus (gpt-fat32 if it lets you, ntfs otherwise). I’d recommend getting yourself Enterprise N LTSB version since it has no useless crap preinstalled (and no win market).
Boot to bios and select your USB drive to boot from
Delete all the partitions in Windows install and start an installation into empty space.
