Switched from Intel CPUs to Ryzen now Grub appears, what should I do?
This situation is unexpected. Initially, the system ran smoothly with an Athlon 3000 and Ubuntu 20.04 LTS. After replacing the CPU, the BIOS changed and Grub appeared correctly. However, upon restarting, the boot process repeatedly restarts to Grub. It’s a small issue but not what I anticipated. How can I resolve this?
Does this indicate that grub isn't locating grub.cfg? Are you using a dual boot setup or multiple drives? It seems your CPU swap hasn't impacted grub functionality.
It seems you suspect the system's default EFI boot configuration was altered. You may want to adjust it accordingly.
Apparently nothing happened. After installing the new CPU and turning it on, the motherboard replied that a new CPU was found and reset the BIOS to its default settings. It seems I didn’t apply any overclocking or XMP profiles, and the only adjustments were disabling TPM settings, which the board doesn’t support. That’s why I was surprised.
Consider updating your grub setup. The BIOS might have randomly changed drive labels, so running grub-mkconfig -o /boot/grub/grub.cfg could resolve issues.
You might resolve it by entering a chroot environment. These paths and commands seem accurate. I'm not testing on Ubuntu. Start a live ISO, run fdisk -l to identify the installation partition, then create /mnt. Enter chroot /mnt, view /etc/fstab, verify if the Fat32 partition exists. If it does, mount /dev/fat32partition to /mountpath_in_fstab. Run grub-install with the appropriate options, and if needed, mount /dev/fat32partition to /boot/EFI. Finally, configure grub-mkconfig and reboot.
