Here are the steps I took to install Linux Mint on a PC (ThinkPad X200T), with assistance from my MacBook.
Note: You’ll need a USB stick.
Get a Linux Mint disk image
First, get a Linux Mint disk image, which includes a bootable version of the operating system and the OS installer.
You can get a disk image on the Linux Mint download page. Here you’ll decide which desktop environment you want to use. I didn’t think about this too much and went with Cinnamon. You’ll also have to figure out whether your PC runs a 32 or 64 bit processor.
The disk image is about 1.5 gigabytes, so downloading in the browser may take a while. I used the torrent download and got it in about 5 minutes.
You should now have a disk image file on your computer that resembles the filename “linuxmint-18-cinnamon-64bit.iso”. The exact name will depend on the version number, desktop environment and PC processor architecture.
Mount the disk image on the USB stick
Plug the USB stick into your computer. First we’ll format the drive so a PC can read it. On a Mac open Applications > Utilities > Disk Utility. Select the USB drive, and click the Erase button. Under Format, select MS-DOS (FAT), and then click Erase.
To mount the ISO image on the USB stick, I use UNetbootin. Download the application and open it. A dialog box will pop up saying”osascript wants to make changes” and ask for an administrator password. Fill it out and continue.
UNetbootin can download a Linux distribution itself, or you can supply a disk image to mount. Since we downloaded one, select the second option and show it where the disk image file is on your computer.
Make sure the right USB drive is selected for mounting, and click OK. The mount process takes about 3 minutes. Afterwards, you can look at the content of the USB drive and see all the files that make up the Linux Mint trial/installer disk.
You can eject the USB and put your Mac away, we won’t need it anymore.
Give USB drive priority boot order
You may need to configure the PC’s BIOS to boot from a USB drive before the hard drive. Otherwise, the system ignores the USB and boots from the hard drive. On my ThinkPad X200T, I press the ThinkVintage button at startup and enter the BIOS setup utility. Then select Startup > Boot, and move the USB drives to the top of boot priority order.
Now, whenever I insert a bootable USB stick, it will load first.
Boot Linux Mint from USB
Plug the USB stick into your PC and restart the computer.
A UNetbootin boot menu will display. Select Start Linux Mint, which boots the OS. This hasn’t installed anything yet, the operating system is just booting from the USB. You can poke around this “trial mode” of the system and see if this is what you really want.
Install Linux Mint
On the Desktop of the booted-from-USB Linux Mint, click the Install Linux Mint icon. This opens an install wizard which should be straight-forward. I check off the “Install third-party software for graphics etc.” I select “Erase disk and install Linux Mint” because it’s all I want on this computer.
Let the installer run. Afterwards, reboot the computer, remove the USB and voila! You are a Linux user. Have fun!
A few extra niceties
Install drivers and multimedia codecs
When you start Linux Mint, a Welcome Screen opens that includes links to install drivers and multimedia codecs. Do both of these tasks if you want to have a good time.
Disable annoying system beeps
My computer woke me up at 4am making a horrifying sound because it was low on battery. I have a hard time just watching scary movies so this was terrifying.
Disabling the beeps will depend on what computer and BIOS you have. On my ThinkPad X200T, I press the ThinkVintage button at startup and enter the BIOS setup utility. Then select Config > Beep and Alarm and disable all.
