Hi everyone,

I have a finely tuned Fedora 40 image that I cloned using Clonezilla (see: https://sh.itjust.works/post/25762756)

I wanted to deploy it on my old Acer Aspire 5737z but it won’t boot. It’s just displaying a — on a black screen for hours.

I’m not so knowledgeable but I guess it means I would have to reinstall the GRUB or whatever.

I’ve booted into my Fedora Live USB and tried the lsblk command people were talking about on the web (I don’t understand the terminal). Here’s the result.

I think the SDA disk is the one I would like to boot from.

Can anyone help me understand what I have to do 😇🙏

    Thanks for the help but I don’t understand anything from the message on askubuntu.

    I’ve tried the sudo mount/dev/sda3 /mnt part though…

    Sorry for my lack of terminal skills

      That’s alright, I’ll do my best to walk you through it.

      Your drive contains multiple partitions (/dev/sda1 through /dev/sda3).
      One of these drives is going to be your EFI partition. This is what your system can read before linux boots, your BIOS can’t understand ext4 / btrfs / etc, but it can understand fat32.
      If you run lsblk -no FSTYPE /dev/sda1 it should return vfat if that’s your EFI partition. That’s what we’re going to mount to /mnt/boot/efi

      I’m assuming that /dev/sda3 is your data partition, e.g. where your linux install is. You can find the filesystem format the same way as your EFI partition. Edit: After determining which partition is which, you’re going to want to mount the root partition, and then the EFI partition
      mount /dev/sda3 /mnt
      mount /dev/sda1 /mnt/boot/efi

      Unix systems have theology of “everything is a file”, all devices and system interfaces are mounted as files. As such, to be able to properly chroot into an offline install, we need to make binds from our running system to the offline system. That’s what’s achieved by running for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
      This is just a simple loop that mounts /dev, /dev/pts, /proc, /sys, and /run to your offline install. You’re going to want to either add /sys/firmware/efi/efivars to that list, or mount it (with -B, which is shorthand for --bind, not a normal mount).

      Once you’ve done this, you should be able to successfully chroot into /mnt (or /mnt/root if running btrfs)
      At this point, you should be able to run your grub repair commands.

        Here is what I’m getting after running through the steps you kindly gave me. The second part is the part where I’m probably not doing right…

          Apologies, I think I got a bit ahead of myself in the description.
          Once you’ve determined which partition is which (in your case, /dev/sda1 does appear to be the EFI partition, and /dev/sda3 appears to be your root partition), you need to mount them in this order

          mount /dev/sda3 /mnt
          mount /dev/sda1 /mnt/boot/efi

                  Since you’re using btrfs, there is likely another subfolder under /mnt. ll /mnt will tell you this, but the drive isn’t still mounted from the other day. When you’re mounting the EFI partition, you’re going to want to mount it to that folder, and not /mnt itself (/mnt/root/boot/efi, instead of /mnt/boot/efi) same for the binds (/dev, /proc, /run, etc)

                    Here is what I’m getting.

                    I’m almost ready to give up on my dream of establishing a perfectly tuned version of Fedora that I can deploy on all my computer just through Clonezilla…
