LICK is a free program to install Linux from Windows without burning a CD or using a USB. It is as simple as installing and running LICK, selecting a Linux ISO image, and clicking install. A few seconds later, you can reboot into Linux. Currently only Puppy Linux-based distributions are supported. LICK runs on any Windows version, from Windows 95 to Windows 10. Check below for any special notes on your Windows version type. LICK is a method to install Linux distributions from inside Windows. It can install directly from an ISO file, bypassing the need to burn it to a CD. Additionally, it installs a bootloader (either GRUB4DOS or GRUB2), so that the user doesn't need to do so themselves. LICK also includes a library, liblick, that can be used in other projects. It is released under the MIT licence.
