I have a Acer Aspire where the hard drive completely failed. It had Windows 8 on it but took advantage of the free upgrade to Windows 10.
I also have a 500 gig hard drive that I reformatted and have been trying to get the computer to install Windows 10. Doesn't want to work. I have a Windows 7 installation disk with key code. I always thought that Windows 7 was a stable program and that I would be happy with that system. I am thinking that in the Firmaware my Acer Aspire does have stored that the system had Windows 10 activated on it. I have had no luck in getting either system installed.
I was able to get into the Acer BIOS and set the BIOS settings to Legacy. I can't set it to boot into the CD for the Boot Order so I have not been able to get the opportunity to install Windows 7. I would sure appreciate any and all help. I formatted the one drive to NTFS and made that the default.
Thanks again. I am stumped.
