I've refreshed this write-up based on a system with Windows 10 and Fedora 39 on LUKS on Btrfs, "installing" Fedora 40 along side via dnf system-upgrade.
The two installations share /boot, /boot/efi, /home, with the two root file systems on Btrfs in their own subvolumes. https://fedoraproject.org/wiki/User:Chrismurphy/Draft/dualboot_teststation Features: * no re-partitioning; * no resizing; * no extra drive; * no installation or reinstallation, system upgrade is used instead; * reversibility, or undoability, i.e. you can delete the "test OS", or for that matter the older system root, with just a few steps. -- Chris Murphy -- _______________________________________________ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
