Linux Mint 20.3 suddenly not booting

Help! Mint has been working beautifully for weeks on a Dell Latitude 6530 business computer, but today it suddenly will not boot. When I turn it on the dell Logo appears for a moment, then two short lines referring to Una flash on for a second, finally the small round mint logo appears and the entire screen goes black. I got to the boot screen (F12) and did the diagnostic test.


Now what do I do? Any help is appreciated.

Hey @Pam!
It would appear something has hit the Dells lately with an update. Yours is the second occurrence I encountered today. When you start the booting process (past the BIOS), hold down the SHIFT button or tap the Escape key to get to your Grub Boot Loader. Then select Advanced Options and select an older Kernel (should be 3rd choice). Does that help?

Thank you for answering, Vasileios. I realized after posting my dilemma that I’d not yet saved anything of importance, so I booted from usb to start fresh. It worked. I’ve not yet gone through the welcome setup. Should I continue or go from here to Grub Boot Loader and select an older Kernel?
Also, my son-in-law produces rodeo videos and has a couple of older MacBook Pro computers. What is the latest Pro that can be adapted easily to Linux? I homeschool his boys and wonder if converting these to Linux would be a good option. Any thoughts are appreciated.
God bless you and the work you do for us.

Hey @Pam!
Naturally, the USB works since it has the older kernel in it. First, try to boot into your grub and select an older kernel to see if it works. Once you get there, execute the following commands, just in case something went wrong during an update:

sudo apt update
sudo apt upgrade -y
sudo apt install -f
sudo dpkg configure -a

All the above are an overkill and it may not be a big of an issue. However, one of those could help. On the other hand, there might be nothing wrong with the update, in which case you can also try:

sudo apt install dracut
sudo  dracut --force
sudo update-grub

And then reboot and allow it to boot normally and see if that works. :slight_smile:

Per your son-in-law, any Macbook Pro that was built prior to 2018 (without the T2 chip) will have an easier time switching to Linux.
