|Important : Before you consider dual-booting your Windows machine with CloudReady, please be aware that we strongly advise users to only install CloudReady in Standalone mode as we will be discontinuing support for dual-booted machines after June 2018. Read more about the sunsetting of Dual Boot here.|
If you machine supports UEFI, but your current install of Windows is in legacy mode (you can check by following our dualboot notes in the directions) you may not need to reinstall Windows in order to dualboot.
