What is everything that is listed after the initial table? I'm trying to reinstall the boot loader but I don't know where the previous Fedora is located. Right now I'm running off a live USB.

I swear this list gets longer by the day...

The script from https://github.com/arvidjaar/bootinfoscript produces a report from which the current boot configuration can be determined. Upload it with the command pastebinit and paste the resulting URL here if you need help understanding it.

You seem to have a penchant for confusion. Fedora has an very good wiki - a good place to start whenever you have a question. Whilst waiting for the bootinfoscript, run this from a live session terminal - it will be much more readable. Use sudo in need, but you shouldn't have to.

Code:

lsblk -f

I want to thank you both for all your help on this and other threads of mine, I apologize if I've been erratic on this forum. This has been a lot of information to take in and I'm just trying to make sense of it all.

[edit] I've figured out how to run the script I think attached is the file, pastebinit: command not found unfortunately.

BW-userx · 02-13-2019, 12:29 PM

chmod +x bootinfoscript
try it again?

I downloaded the file and extracted it to desktop

Why not leave it in the default Downloads folder? If you did move it to the Desktop, you will need to change directories to your /home/user/Desktop directory to run the commands to make it executable and then run the script.

mrmazda · 02-13-2019, 12:37 PM

sudo sh bootinfoscript works too.

it doesn't say anything when I hit enter after that for some reason. but I found the file I was in the wrong directory I suppose, and the names were different

zavmat · 02-13-2019, 12:50 PM

Code:

[root@localhost-live /]# sudo sh bootinfoscript
sh: bootinfoscript: No such file or directory
[root@localhost-live /]# chmod +x bootinfoscript
chmod: cannot access 'bootinfoscript': No such file or directory

Is the problem the directory I'm in? do I need to cd directly into the file first? The answer is yes, I do.

However chmod +x still does not return an error but doesn't seem to do anything in this case.

Changing to the directory the script is in first is one option. The full pathname is required to run a script that is not in the current directory, e.g.:

Code:

sudo sh /home/me/Desktop/bootinfoscript

The same concepts apply to using chmod.

yeah that would be the czuse of it and what everybody else said on this matter. you need to be in the same dir, which i thought you were, and or absolute path/filename even then you will not get any feed back from that command that is actually worked. if you have yourself setup properly before issuing the command it just works. then ./filename or absolute path/filename to execute it. the . (period) is present dir, and the / is the path to file, for a lack of a better way of saying it.

present directory/filename
./filename

absolute path

/home/username/Downloads/filename

leading slash / before name.

Code:

sudo mount /dev/mapper/fedora-root /mnt
sudo mount /dev/sda5 /mnt/boot
sudo mount /dev/sda1 /mnt/boot/efi
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo mount -o bind /run /mnt/run
chroot /mnt
dnf reinstall grub2-efi shim
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
exit
sudo umount /mnt/run
sudo umount /mnt/sys
sudo umount /mnt/proc
sudo umount /mnt/dev
sudo umount /mnt/boot/efi
sudo umount /mnt/boot
sudo umount /mnt

I believe all relevant information has already been provided, from within the Live CD, execute the commands in order posted in the code box above to reinstall Grub2. You may not need to install anything if you feel it's just the boot files in the EFI partition that are missing or corrupt, in which you can try skipping the "dnf reinstall" command and just do the grub2-mkconfig command, this is if you feel there is nothing wrong with grub installation already present in root and boot directories. The "sudo mount -o bind /run /mnt/run" command should give internet access in the chroot if not mistaken.

Grub appears to be fixed but none of the options listed can boot. Why sda5 which is only 1G in size and sda1 which is 200M?

zavmat · 02-15-2019, 05:22 PM

what about loop1 or loop 2?

Code:

loop1             7:1    0   6.5G  1 loop 
├─live-rw       253:3    0   6.5G  0 dm   /
└─live-base     253:4    0   6.5G  1 dm   
loop2             7:2    0    32G  0 loop 
└─live-rw       253:3    0   6.5G  0 dm   /

These seem like the right size at least.

I remember making the sda6 partition because it was so large, and I told myself not to waste the space in the future in case I need to reinstall and can't figure out how to delete the partitions.

sda5 is Fedora boot partition, sda1 is System partition where the UEFI firmware interface looks for boot information.
All the loop devices and /dev/mapper/live devices are part of the Fedora live CD
