Install windows error on Acer Aspire A315

Gregster

Hi folks.
Hope you can help.
Just got an Acer Aspire A315-51-341M refurb.
Switched on for 1st time.
Starts with Install Windows Error - i tried turning it off and then using Alt + f10. That leads to it being stuck with the Acer logo on the screen.
Turned it off and reset the battery, and turned back on but got the Install Windows Error again.
Pressed f2 for blue set up screen. 
Reset the boot mode to default and then restarted and got 'no bootable device'.
Reset it back to legacy and then it goes back to Install windows error.

I think the above covers the suggestions/ answers to previous posts that i could find, but any help would be superb.
Really appreciate any advice.

Thanks
G.

Must reset BIOS to be UEFI bootstrap, not legacy. Then shut machine off. Then turn it back on again and F2 back into the BIOS menu. If the BIOS Information tab does not identify the HDD or SSD, then immediately return the machine to the vendor as defective for a refund or exchange. Jack E/NJ
