Invalid system disk error

by Chriskey85 / September 21, 2016 4:01 PM PDT

Hi. I just bought and installed new ram into my windows 7 pc. And now it says

Invalid system disk
Replace the disk, then press any key

Could this be because the ram is bad?
Not compatible? (though I checked and a site said it was)
I knocked a wire loose while I had it opened up?

Remove the new ram and install the old ram.
If the machine works you have a problem with the new ram.
