Curious about Linux but not ready to wipe Windows? Dual-booting keeps games and specialist Windows software while you explore Ubuntu, Fedora, or Linux Mint on the side. Reversible if you partition carefully and back up first.
Before touching partitions
- Full backup to external drive — photos, documents, projects.
- Create Windows recovery USB (Settings → Recovery).
- Disable Fast Startup (Power Options → Choose what power buttons do).
- Disable BitLocker temporarily if enabled — or know recovery key.
- In Disk Management, shrink C: by 50–100 GB minimum for Linux root + home.
Installation walkthrough
Download Ubuntu LTS ISO. Flash with Rufus (GPT, UEFI) or balenaEtcher. Boot from USB (F12/F2/Del). Choose "Install alongside Windows" — installer handles GRUB bootloader. Manual partition only if you understand ext4, EFI System Partition, and swap — mistakes erase data.
First boot on Linux
Run software updates immediately. Install proprietary drivers if offered (NVIDIA). Enable third-party codecs for media. Access Windows NTFS partitions — read-write if Windows fully shut down; read-only if Windows hibernated.
When things go wrong
Windows Update overwriting bootloader — boot Ubuntu live USB, run boot-repair or reinstall GRUB. Secure Boot blocking drivers — disable in BIOS temporarily or use signed drivers. Start with Ubuntu or Linux Mint — largest forums and clearest installers.
Is dual-boot worth it in 2026?
WSL2 on Windows covers many dev workflows without rebooting. Dual-boot still wins for full desktop Linux experience, GPU passthrough experiments, or learning systemd and package managers natively.
