Solved Grub

[Madd00x]

Hello, after the upgrade Grub was not installed due to lack of space. I removed some MB from /boot/efi and added them to /boot.
How do I rewrite Grub from live USB?

Hi, do you have other OS's on your disk ex. Windows or only this 1 Linux?

Grub should be installed to /dev/nvme1n1p1 which is EFI partition.

 

[Condobloke]

the upgrade Grub was not installed due to lack of space.

Was this install partitioned manually or were the partitions taken care of by the installer ?

/dev/nvme1n1p1 2048 411647 409600 200M EFI System

....??....I am seeing 200M....is this disc lvm partitioned?....encrypted?.....is there a chance there is another OS on the disk...eg windows and you have installed part of lInux to a windows file system ?

I only have Linux in my 2 sdd.
the /boot dir is in nvme1n1p3 (753MB)

And what is your 2nd disk nvme0n1? data drive?

If you're doing this from live USB you need to have Boot partition mounted to /boot and EFI partition mounted to /boot/efi
If these partitions are mounted to these mount points then it's as simple as running grub-install as root or sudo.

See here:

GNU GRUB Manual 2.12: Installing GRUB using grub-install

GNU GRUB Manual 2.12: Installing GRUB using grub-install

www.gnu.org

That's what I would do, I've never had to do it by hand though so maybe wait until someone confirms this.

YES, the initial setup was having /boot and /boot/efi, but as i wrote i got low space in the boot partition then i resized moving from efi to boot.
I need step by step how to do

I have installed Fedora.

I think it's wrong to move from EFI to Boot because those moved files will be useless, if there is not enough space on EFI then partition should be resized, and this mean reformatting, creating new partition layout and system reinstall.

If you're installing new system then there is nothing to lose to reformat and grub should install without hackery during install.

I already did... and im not reinstalling a new one, but i htink would be better, at this time i would have everything work fine... The point is to learn how to do, without formatting everytime i get this problem!

During installation and formatting step you can enter advanced setup and manually partition drive.

The exact steps depend on distro you're installing, for Debian there is "expert install" and lets me partition the drive in detail including swap partition etc. etc.

The default partitioner doesn't do the job well for me, so that's how I get around it.
EFI partition should be 512MB formatted as ext4, Boot partition 1GB as ext4 and swap should be RAM x 1.5 formatted as swap, the root partition consumes the rest of disk space and is formatted as ext4, all of which formatted prior installing system.

I know how to partition disk, nex time i will give 1GB /boot, i need to learn how to repair grub without reinstalling everything...
