Windows 8.1 Not installing on a brand new PC

[Sweetpete72]

After completing my new PC I try to install windows 8.1 through a disc and a usb and both work fine up until I get to the screen that tells me to select a hard drive. Neither of them work and when I choose one and click next I get a message that says "The partition you selected might contain files from a previous Windows installation. If it does, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will not be able to use your previous version of Windows." I click ok and then nothing happens the little message just goes away and comes back when i click next. I have a 1tb seagate barracuda and no other drives installed and the drive is being detected in my bios so im not sure what to do. Any help is appreciated

Try this: Check that your BIOS has the hard drive in "AHCI" mode and try the setup again
