Acer Laptop, Error: "No Bootable Device" After installing OEM Win7

Hi,

I was asked by someone to install Windows 7 on their Acer Aspire E1-570 running windows 8.1.
I have since formatted the drive and installed Windows 7, but now I get an error stating the above, No Bootable Device, Hit Any Key.

I think I'll need to reinstall whatever partitions etc. Acer had originally setup on there because currently there's no option to find the drive at all.

Any help would be greatly appreciated. Thanks.

Did you follow all the steps to Downgrade Windows 8 to Windows 7 ?

I did not!
I'll take a look at that and give it a try tomorrow, thanks!
