this is my second post here, and i didn't know ehere to put it, so i'm posting it here. everytime i shut down my laptop, or restart it, a interface flashes and shows various errors. today i tried reading some log files, in /var/log, and i've seen some lines stating like "grub failed boot detection". i've added screenshots of those as well.

Also i might've added some unnecessary snapshots i don't know. I'm just starting. Thanks :)

G'day Debdut :)

You didn't tell us in your last Thread, and you haven't in this one -

What Linux Distro are you using?

2. Besides the errors at start and finish, are you able to run a session normally, or are there problems? It appears that you can access your Browser OK, and login to this site.

3. Can you give us the output of the following command from Terminal

Code:
cat /etc/default/grub

Thanks

Yesterday after posting this thread, while restarting it was stuck on a purple screen. No matter how many times i tried restarting it, it still showed the same old purple screen .

I was using Ubuntu 18.10 , all latest updates .
Also i forgot to mention the last time, my system was allocating too much Ram memory. Everytime i entered "free -m" , even after a fresh start, the system was taking 1.2 GB of memory. And also it was heating much. About the other pobleprp, not everytime i saw it, but about 40-50% of the time, it lagged a bit more than it should. Some apps took forever to open.

My device specs - I5 8th gen, Amd Radeon 530 Graphics(2 gigs), 8 gigs of ram. 2 TB hdd. I bought it recently, with DOS as pre-installed.

I bought it specifically for learning purposes, (unix shell scripting, C, c++, Assembly). Yesterday after that purple screen stuck, i researched a bit, and installed Kali Linux, lxde version ( as it is lightweight. Less memory allocation, less heating) .

Also, after buying this device, i firat time installed 18.04 Ubuntu LTS version. It came with kernel 4.15, which didn't have support for the touchpad , or couldn't detect any graphics card. Then i updated the kernel to latest stable build, 4.2 , still no graphics solution, but tpuchpad got working. And from then i started seeing those shutdown errors. So i formatted the whole disk and reinstalled 18.10, this time, graphics were working, as well as the touchpad. But then this happened yesterday. So I left Ubuntu, and switched to kali lxde.
