Yes, I do have my old hard drive. they gave it back to me because I was going to get someone to transfer that data. when I turn my computer on I have to keep hitting the delete button for it to go into the BIOS SETUP UTILITY. Once I am there I have to go to the Boot Options. I was told to make sure that my 1st boot device was CD&DVD. That is listed in the 1st boot. I did F10 to save it and restart computer. I inserted my windows 8.1 system recovery disk and it will run. While loading the word GATEWAY comes up on my screen and then I can hear it running for a few minutes. Next the words PRESS ANY KEY TO BOOT FROM CD OR DVD APPEAR at which time I hit enter. I can still hear the system moving. Then the words WINDOWS BOOT MANAGER appear and then below it says "windows failed to start. A recent hardware or software change might be the cause" then the system automatically restarts. If I let the system start up on its own and don't touch anything the next thing that comes up is Reboot and select proper Boot Device or Insert Boot Media in selected device and press key.
I had a friend of mine tell me that the UeFi needs to be turned off and to turn on legacy mode. I can't find that anywhere and don't know what to do.
I have no idea what to do and need direction
