Error: "btrfs" file system does not support blocklists

– Please Write here your help request –

Hi :slight_smile:

I used windows and ubuntu in dual boot, but recently formatted my hard drive and installed windows and later parrot security (dual boot) when i restarted the machine i found the following error:

Error: Unknown Filesystem
Grub rescue >

I used the following commands to exit grub rescue mode:

set root=(hd0,sda2)
set prefix=(hd0,sda2)/@/boot/grub/
normal insmod

And it worked, I managed to open Parrot, but to get rid of this problem I had to run the following command in the terminal:

grub-install /dev/sda2

But it returns the following error:

grub-install: error: “btrfs” file system does not support blocklists.

I’ve already tried running this last command on parrot in live mode (Pendrive), but it returns the same error:

/dev/sda2 - This is the Parrot partition

Parrot OS
Version 4.11 64bit
Linux Kernel 5.10.0-6parrot1-amd64 x86_64

Memory: 8GB
Processor: Intel Core i7-4600M CPU @ 2.90GHz x 4

ATT: If you have any spelling mistakes, I’m sorry, I speak Portuguese, and I put everything in a translator lol
Thanks :slight_smile:
