Hi, a couple of months ago, after the last windows update, something gone wrong with the usb used for it (not enough space on the pc).
The usb became useless and the update couldn’t proceed, I’ve got this message “insert the usb to continue the installation”, even if it was connected.
Anyway, I’ve tried to instal it from microsoft using a second usb but nothing, with F7 I could only make a clean installation but I’m afraid to loose my office license (bought just for that pc).
Do you think I could try again with Hi10 Pro Windows(2017.07)?
my HI10 is Hi10 HQ64g421707009.
Thank you
