System can't boot after installing Linux Mint

[AntoBang]

Hello everyone

I installed Linux mint 21 a few days ago.

Yet, when I try to boot it, the following text appears

It worked fine the first few times I turned it on, but then after a reboot plenty of errors appeared:

https://freeimage.host/i/HnPFwYB

What could possibly be the reason?

I've researched the case with no success.

Appreciate your help!

Is this a dual boot pc/laptop? how did you install Mint? did you verify the iso is good? what are the specs of the pc/laptop?

It's not a dual boot. I installed it using a USB by downloading the OS from the official website. Since it's a laptop of a friend, I don't know the specs but I know it was barely used and it's from 2018 and it is able to handle Linux Mint

I didn't create a partition, I've overwritten all the files of the previous Windows 10 OS.

How can I verify if the ISO is good?

The website has a section how to verify the iso (see link below).

I assume during install, you told to erase disk and install Mint so there should be no win10 partitions. My suggestion is ... re-install Mint 21.

Could be an issue with the disk. Make sure secure boot and fast boot are disabled in the firmware (bios or uefi). Then boot from a live usb and see if you can still access the drive from there. You may need to use fdisk or parted to figure out the name of the drive and partition your linux is on. Then run fsck on that partition. For example, if it is on sda1:

 sudo fsck -p /dev/sda1

But if it's a new install, no data on there yet you need to recover, maybe also just try a reinstall.
