Operating system not found
I replaced the hard drive on a Acer Aspire V5-571 due to the old one crashed and couldn’t boot anymore. It was a windows 8 but i installed a hard drive that has windows 7 installed on it. Now when i’m trying to boot, i just get the message “operating system not found”. I can’t seem to get it into bios or anything.
