Total noob here so please be patient:)
As the title says, when I boot my computer, I get multiple errors, I'm new at linux so I don't really know what they mean, here is a picture of the errors I get:
I have a laptop Acer Nitro i5, I have never opened or modified it before.
When I first installed ubuntu I also had this errors but since I was changing from windows 10 I thought it was normal so I just let it pass, this error shows a few seconds and then my OS just boots without problem and I can use my computer without any inconvenience.
It was all okay until a week ago another problem showed up at booting, and this one didn't let my computer boot automatically, I had to execute the "fsck -f" command followed by my hard disk name (/dev/sda2) and fix the errors manually I had to do this every fourth time or so I used my computer. I heard that when this problem shows up regularly it means the hard drive is damaged, or the OS didn't install correctly, so I just reinstalled ubuntu an hour ago and I got the errors of the photo.
For now I have no problems, and I haven't used the fsck command, but I want to know, should I change my hard disk? are these problems something to worry about? Or can I use my computer and ignore them? Thank you all in advance for your attention and time:) I hope you all have a nice day!
