Windows 8 and GPT to Windows 7 and MBR Complete Conversion

I have a Dell Inspiron 3520 (I believe, can't check at the moment) that I want to wipe 8 off of completely, partitions and all, and start with a freshly formatted MBR drive with windows 7. I know I cannot completely destroy all of the partitions within Windows 8 because its running on the drive. can I do it with Gparted within a a Linux live USB or some other stand alone program, and if so, any suggestions and help with it? Data loss is not a problem. Nothing on the drive needs to be saved.

If this is a PC which came with Win8 preinstalled then it should have Secure Boot, so the first thing you'll need to do is boot into BIOS setup to turn it off in order to install any other OS: DownUPgrade Windows 8 to Windows 7.
