How to dual boot Linux and Windows
Dual booting lets you keep Windows and add Linux on the same computer. At start-up you choose which one to use. It is a good way to try Linux for real without giving up Windows.
What to prepare
- A full backup. Changing partitions always carries some risk.
- Free disk space. Around 40 GB is a comfortable minimum for Linux plus your files.
- Your BitLocker recovery key if Windows disk encryption is on.
- In Windows, turn off Fast Startup so the disk is fully released.
Steps
- Boot from your Linux USB drive.
- Start the installer and choose the option to install alongside Windows.
- Use the slider to set how much space Linux gets.
- Finish the install and restart. A menu will let you pick Linux or Windows.
Good to know
- A separate second drive for Linux is the safest setup.
- Major Windows updates can sometimes change the boot menu. Keep your Linux USB drive handy to repair it.
