my answer probably may be incomplete, but I guess your UUID for your root partition in /boot/grub/grub.cfg still points to the old root partition on the old disk. I don't know if it adequate to change this by hand via vi or an another editor. other question I'm thinking about are - is your PCIe adaptor seen at all by your system ( => lspci) and - is it bootable first step: you should still be able to boot your system from your old disk, but I guess only via BIOS boot menu (on MSI boards: F11-Key) [in my Bios M2-nvme became the very first boot device, so default boot device has changed and needs adjustments] => lspci => PCIe adaptor and nvme seen: yes/no ? => blkid => UUID from your new root partition on the nvme next step: after making a backup of your old grub.cfg and changing the UUID in grub.cfg on your ssd (!!!, needs to mount extra). after reboot you should able to load your system from the root partition on the nvme. - maybe via Bios boot menu fetching the ssd as first boot device - next step: with some luck you are able boot (via Bios Boot menue) from your nvme after adjustments in grub.cfg ON the nvme - don't know if it works cause no experience with PCIe-adaptor - open question: =========== - sudo grub2-install ... <nvme> ? - sudo dracut -f /boot/initramfs-$(uname -r).img $(uname -r) with parameter of the root partition on the nvme ? => man dracut _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
