Hdd broken? chuwi logo loads, win 10 doesnt load, linux wont load

hello

i ordered the windows 10 tab , after the “reset win 10” option the screen stays black (with the cursor following my finger ) and after the chuwi logo no win 10 will start

linux also wont load, same error — the battery is fine and fully loaded

and the bios says " hard disk Umknown S0J38Y 4401B7" - is the HDD broken?

how can i restore win 10 on my chuwi hi13 tab?

kind regards
