I am getting the following error messages during boot (please see attachment).

What is causing this & how to fix it ?

Both of the errors are related to your GRUB install.

This article should help with the environment error: https://www.linuxsysadmins.com/grub2...ock-too-small/

And this one with the hwmatch error: https://askubuntu.com/questions/7663...ommand-hwmatch

Have you searched the internet for hwmatch? Here is a possible answer: https://askubuntu.com/questions/7663...ommand-hwmatch. Of course, whether this answer matches your situation, only you can know. You do seem to have Ubuntu, though.

My suggestion: Go through the web sites that mention hwmatch, in particular those that contain solutions. If none matches, come back to Linuxquestions and provide more context, such as when this message occurs during the startup, and what messages follow, does the computer boot in the end, what distro and version are you running, have you ever booted without this message, have you changed anything to the boot configuration.

Of course, also go through the web sites that mention the environment block error.

I have already read the links you suggested. I need to know exactly what steps I need to take in order to fix this.

I am using Ubuntu Budgie 20.04. These messages started appearing just yesterday. I shutdown the PC then cleaned it by blowing air & when I rebooted it I saw these messages for the first time. Now if the cleaning & the error messages are linked or just I coincidence ? I don't know.

.It could be coincidence, but maybe, check all of your connectors to make sure you didn't knock any loose.

I have already done that. I am getting a feeling that this problem is a tough one. So far nobody has offered a solution.

You haven't given any information on what you have attempted to do, if you had recently done updates or if you can still boot into your system.

Are you able to boot into your system?

Yes I have done updates. I check for updates everyday & install them as soon as they are available.
Yes the system boots without any input from my end. The screenshot that I attached that screen stays for like 10 secs & then the system proceeds to boot as usual.

Hi,

Are you running a UEFI system?

Hwmatch is a 32bit Grub module that isn't present in the 64bit version of Grub.

I'd guess that you have multiple versions of Grub installed..

A recent install of Linux Mint 20.1 onto SWMBO's new laptop installed both Grub-pc and Grub-efi-amd64.

The fix here is easy, just uninstall Grub-pc, ensure that Grub-efi-amd64 is installed (if using UEFI) and rerun update-grub (or update-grub2 if your distro uses it.).

Your distro package names (and tools) may be a little different, but it should be easy to identify the required packages.. If unsure, just ask here..

To determine if your booting in uefi or legacy mode is the existence or not of /sys/firmware/efi directory. What is the output of

Thanks guys for the replies. I became both fed up with Ubuntu. I wanted to try something different so I searched the web about the most stable distro & found Debian so I downloaded LMDE & installed it. As you know Debian too uses apt so its an easy transition.
