It can be a big tricky if this is BIOS firmware rather than UEFI. I'm guessing it's probably UEFI in which case you can do the installations in any order. For BIOS, it really should be Windows first, Fedora last or else you get into a situation where Windows steps on GRUB and you'll have to repair it by reinstalling GRUB (i.e. grub2-install).
Backup first. From Windows, download the installation media creation tool and have it make installation media. Do not install. You can also create Fedora USB stick media with Fedora Media Creator for Windows. https://www.microsoft.com/en-us/software-download/windows10 https://www.microsoft.com/en-us/software-download/windows11 Then boot a Fedora Live ISO and obliterate the entire disk. If it's an HDD, you can use the wipefs tool. If it's an SSD or NVMe, you can use blkdiscard command. Now install Windows first if the firmware is BIOS. Fedora last. If firmware is UEFI, the order doesn't matter. I agree with the suggestions to use Windows' tools to shrink NTFS and its partition. But more importantly make sure to disable Fast startup.https://dev.to/xeroxism/how-to-disable-fast-start-in-ubuntu-windows-dual-booting-setup-4akn -- Chris Murphy _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-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/users@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
