I have Acer Aspire v5 laptop with Windows 8.1. I got new PC and I didn't turn on laptop for quite a while. Yesterday I needed some files from it, but when i turn it on, it just kept spinning Acer, so I changed Boot Mode from UEFI to Legacy. After restarting it it says "Operating system not found". I had all pictures, music, files for school on it.. So how can I access my Hard Disk and get all my files back?
