Programmes took an age to shut down, sometimes taking several minutes. It wasn’t confined to one programme. Any programme seemed to be affected. Also I would occasionally get a screen full of code on shut down [or boot, I can’t remember!] that flew past too quickly to read.
Then I started getting messages that my disk was full. This was worrying as I have a 1Tb HDD with windows/Linux dual boot. The Linux root partition was 50Gb and the home partition was 500Gb, both being big enough to avoid problems. Or so I thought. It was the root partition that was nearly full.
A quick check with Disk Usage Analyzer showed that the problem was log files. Tons of ’em. I deleted them [carefully].
Next I took a photo of the scrolling text. That at least allowed me to read some of it.
I selected a likely looking piece from one of the lines – “PCIe bus error severity=corrected” – and did a search on the web. I quickly found a solution.
Edit the file “/etc/default/grub” as Root user [making a backup of it first, of course].
I tried an update to the manager via the terminal. That didn’t work. I tried a few other suggestions that I discovered on the Web. Still no go. I decided the simplest solution was to reinstall 21.1 from the new ISO. I downloaded it and stuck it on a USB key.
Before booting into the key I went to backup my software selection. The Backup Tool didn’t work either. It just didn’t list any software. I resigned myself to a system reload. But before I started I thought I’d test Software Manager. That seemed to work so as a last resort (just for the devilment) I installed Gnome Update Manager. That worked, though it was a different program from the normal! It suggested a load of updates but I just selected Update Manager and Backup Tool. That worked.
In my Administration Menu I now had Software Updater and Software Manager. I tried the latter again.
It worked perfectly this time, as did Backup Tool. I applied all the updates.
I was very happy with it and straight away went about installing Linux Mint as a dual boot.
That’s when the problems started.
Windows 10 works perfectly (I use the word in the sense that it did what it was supposed to do albeit very slowly) as did Mint. I had split the main 1Tb disk in two and all was fine except for the boot process.
Switching on from a cold start was generally fine. Mint (my default, of course) ran perfectly. The problem would arise on a reboot. The boot loader would fail and I would either get a blank screen with a GRUB curser – “C:grub>” – or the bootloader showing the two operating systems but neither choice would work and just display an “error: command failed”. A soft reboot (Ctrl+Alt+Del) just brought me the the start of the loop again. A hard reboot (switch off/on) wasn’t much better. Eventually after several soft or hard reboots I would be able to get into either OS.
I tried many things to fix this problem. I had scanned the hard drive from both systems so I knew there were no flaws there. I did a factory restore but that didn’t fix anything. I reloaded Mint. I ran Boot Repair with varying options. I mucked around in the bewildering settings in the Dell Boot Setup. Nothing worked.
I resigned myself to a lot of future frustration but at least I could eventually get into the OS I wanted.
