Hi. So I have an Acer Aspire one 725 laptop. I took out the hard drive and put it in my desktop computer, and wiped it clean and installed Windows 7 on it ( had win10 before). Then I put it back in the laptop and now it says 'No bootable device- Please restart' or something like that.

Is the laptop compatible with windows 7? It's from 2012 so I presumed it would be.

And is there anything I can do to fix this?
