I'm trying to repair grub after a Win10 install. Here's the content of my disk:

Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xc4476e04

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1            2048    206847    204800   100M  7 HPFS/NTFS/exFAT
/dev/sda2  *       206848 566209347 566002500 269.9G  7 HPFS/NTFS/exFAT
/dev/sda3       566210560 567169023    958464   468M 27 Hidden NTFS WinRE
/dev/sda4       567171072 976773167 409602096 195.3G  5 Extended
/dev/sda5       567173120 976773119 409600000 195.3G 83 Linux

sda2 contain wind10 and sda5 a btrfs volume (no encryption, no compression)

I had no luck with boot-repair, so I followed the instructions here: https://bugs.launchpad.net/boot-repair/+bug/1721263

Boot with a Linux LiveCD
sudo mount -t btrfs -o subvol=@ /dev/sda5 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt
grub-install /dev/sda

Here I get the following eror:

Installing for i386-pc platform.
grub-install: error: cannot open `/boot/grub/i386-pc/hello.mod': No space left on device.

sda5 has 56GB of free space. What is going on and how can I fix my system? Thanks

  • @user535733 I added these informations. I not sure how to interpret them. It's like the drive is read only.

  • Your Linux partition is completely full. So full it seemingly cannot even boot. So boot-repair won't work until you free some space. There are many my-disk-is-100%-full questions. Note that some of the questions involve a full "/boot partition" - those solutions WON'T work for you; different problem.

  • It's impossible, my partition was far from full, at least 50GB free. Ubuntu was fine until Windows 10 messed with the boot sequence.

@user535733 was right, the BTRFS filesystem was full, more precisely out of metadata space.

this was resolved here

After that I could install grub without any error.
