Want to install Linux MINT Cinnamon on Dell Latitude D630, 64-bit, 2 GB ram, 80 GB HDD, DVD+RW DVD/CD ROM. Currently running MS-Windows 7. Would like to load fresh Linux ONLY MINT Cinnamon - no Microsoft. I also have desktop PC running Windows 10, and have downloaded Mint ISO which can be moved to CD/DVD. How can I replace Win 7 with Linux? How do I format the HDD, and what do I need to execute(?) the ISO file to do the install? Any help/direction would be greatly appreciated. Thanks.
