Sonnet 4.5 Fedora Repair Plan: Manual Recovery Steps from Live USB

Sonnet 4.5 Fedora Repair Plan

Overview

A step-by-step guide for manually repairing a broken Fedora installation using the Fedora Live USB terminal. This recovers GRUB and boot files without reformatting /home or the root partition.

---

Step 1: Identify Your Drives

Run:

lsblk -f

Find your 990 Pro (usually /dev/nvme0n1 or /dev/nvme1n1). Note the partition numbers for EFI, boot, root, and home.

---

Step 2: Mount Fedora Installation

sudo mkdir -p /mnt/fedora/boot /mnt/fedora/boot/efi /mnt/fedora/home
sudo mount /dev/nvme0n1p4 /mnt/fedora   # Fedora root
sudo mount /dev/nvme0n1p2 /mnt/fedora/boot
sudo mount /dev/nvme0n1p1 /mnt/fedora/boot/efi
sudo mount /dev/nvme0n1p3 /mnt/fedora/home

Replace device names if needed (use lsblk -f to confirm).

---

Step 3: Check Fedora System

ls -la /mnt/fedora/etc/
ls -la /mnt/fedora/usr/
ls -la /mnt/fedora/home/

Make sure directories exist. If yes, Fedora install is intact.

---

Step 4: Chroot into Fedora

sudo mount --bind /dev /mnt/fedora/dev
sudo mount --bind /proc /mnt/fedora/proc
sudo mount --bind /sys /mnt/fedora/sys
sudo mount --bind /run /mnt/fedora/run
sudo chroot /mnt/fedora

---

Step 5: Reinstall GRUB & Kernel

grub2-install /dev/nvme0n1        # Or /dev/nvme1n1
grub2-mkconfig -o /boot/grub2/grub.cfg
dnf reinstall kernel -y
dracut --regenerate-all --force

---

Step 6: Fix fstab

blkid   # Get correct UUIDs
nano /etc/fstab

Update fstab entries for /, /boot, /boot/efi, and /home using actual UUIDs.

---

Step 7: Exit & Unmount

exit
sudo umount /mnt/fedora/run
sudo umount /mnt/fedora/sys
sudo umount /mnt/fedora/proc
sudo umount /mnt/fedora/dev
sudo umount /mnt/fedora/boot/efi
sudo umount /mnt/fedora/boot
sudo umount /mnt/fedora/home
sudo umount /mnt/fedora
sudo reboot

---

Step 8: Boot & Verify

• Remove USB.
• Boot into Fedora from GRUB.
• Check files, run lsblk, verify /home and system files are present.

---

Step 9: Troubleshooting

• If mounting fails, verify device names and run fsck.
• If GRUB or kernel commands fail, use alternate commands (grub-install, grub-mkconfig).

---

This plan preserves all data on /home and existing Fedora system files.
