I dunno. Maybe this is hard drive fault but I’m not sure. I have two same hard drives and one of them works.

Ok, let me descibre my problem.
From time to time, I have problem with grub and starting parrot os. I mean, when I want to start system, grub stucking (or giving read error) or when I start system, it crushing without any reason and I have to restart it. I searching syslogs but I didn’t find anything. Fortunately, I had backup and when I restore backup, everything is cool (yeah, I know I could repair grub but I can’t do this). Is is problem with grub or maybe with parrot os? Or maybe with hardware? I tried describe problem as I can but ask me for more details if you want and I will try answer

PS someone think parrot os is unstable? Maybe I’m the only one who has this problem

Please help the helpers by adding some screenshots.

It is as stable as Debian testing is. And it could have some different specific issues by some different packages or preinstalled packages.

Please help the helpers by adding some screenshots

for now, I have only this

by the way, thanks for fast answer. I’m impressed.

There are tutorials about fix boot partitions in community. Please search, try it with live usb

Ok, I know now how to fix but I don’t know why grub and system are crashing from time to time without any reason

Sounds like hard disk or memory corruption.

sudo apt install memtest86+

Reboot and choose at Grub2 menu.

Ok guys, probably found a problem. This is not disk or memory. I think this is problem with GPU and drivers. Linux has problems with drivers, especially with nvidia GPU drivers. Any ideas what should I do now? I’m not sure what to do first so I will be grateful if somebody show me da way :smiley: (still, I keep trying by myself. If I found something, I will wirte. Maybe somebody has similar problem)

Ok guys, I found the problem. You were right Masmer, this is hard disk corruption. Fortunately, I caught this:

Can you tell what this error mean please?
