This release contains four files.
You can choose one of these files depends on your devices. In doubt, try the 32-bit ISO for legacy BIOS devices and 64-bit files for UEFI devices.
To use an ISO file, Linux users could just dump it into a usb drive to create a bootable usb stick like :
dd if=cm-x86_64-14.1-r2.iso of=/dev/sdX
where /dev/sdX is the device name of your usb drive.
Windows's users can use the tool Win32 Disk Imager to create a bootable usb stick.
Please read this page about how to install it to the device. Except the traditional ISO files, we also package android-x86 files into a Linux package rpm. It allows Linux users to easily install the release into an existing Linux device with a standalone ext4 root partition. On an rpm based device (Fedora/Red Hat/CentOS/SUSE...), just install it like a normal rpm package:
sudo rpm -Uvh cm-x86-14.1-r2.x86_64.rpm
All files will be installed to the /cm-x86-14.1-r2/ subdirectory and a boot entry will be added to grub2 menu. Reboot and choose cm-x86 item from the menu to enter the system.To uninstall it:
sudo rpm -e cm-x86
On a deb based device (Debian/Ubuntu/LinuxMint/...), please use the alien tool to install it:
sudo apt install alien
sudo alien -ci cm-x86-14.1-r2.x86_64.rpm
repo init -u git://git.osdn.net/gitroot/android-x86/manifest -b cm-x86-14.1-r2
repo sync --no-tags --no-clone-bundle
