To keep things straight I am going to refer to the desktop by its name Phoenix.
The screenshots in my last post of the Federal Live mode were made on the desktop Phoenix. I was so glad to have Linux booting on that computer even if wasn't Mint Live. I copied the screenshots to a flash drive so I wouldn't lose them. I realized the live mode always reset everything when it was booted again.
Lowering the CPU temperature
In the Phoenix BIOS I lowered the multiplier from 10 to 7. This should lower the temperature.
CPU speed = 200MHz x 10 = 2.0GHz (default)
CPU speed = 200MHz x 7 = 1.4GHz
I also had to disable Cool'n'Quiet and Core Performance Boost. Otherwise, the multiplier change wouldn't have any effect.
After I booted into Windows 10, the CPU clock speed always stayed at 1.4GHz.
Trying to boot to Linux Mint
I still couldn't boot the Linux Mint ISOs. I tried several versions.
Linux Mint Cinnamon 22.3
Linux Mint Cinnamon 21.3
Linux Mint Xfce 22.3
Linux Mint Mate 22.3
Linux Mint Lmde 7 Cinnamon
They all hung on the green Linux Mint logo.
I wonder if an older version of Linux Mint would work better?
Note, I started trying to boot Linux Mint on Phoenix on Monday I tried both the USB 2.0 port on the front and a USB 2.0 port on the back panel. The boot failed on both the same way.
Trying to boot to Linux Fedora
Fedora booted the the Live Desktop in a little over 2 minutes. Like yesterday after about 15-20 minutes it didn't totally crash but most applications when selected wouldn't run.
I found this online:
If your Fedora Live USB stops working or freezes after a certain amount of time, it is usually caused by a conflict with Nvidia graphics drivers, a corrupted USB flash drive, or a timeout in the initial setup screen.
My Nvdia GTX 560 GPU is 15 years old and may have conflicts with Wayland. Maybe switching back to X11 would be more stable.
Before it crashed I ran "sudo dmesg". The results are attached to this post.
After it crashed I rebooted. I immediately installed it in the unallocated space on disk1. The Install Finalization seemed to crash when done. I had to reboot to get past that. Linux Fedora 44 loaded when I selected it in the boot menu. I decided that testing of it would be easier in the installed rather than the live mode.
If I have any more crash problems I may decide to switch to X11 or pick up a much newer GPU. I had thought about a 1030 or other 10 series but maybe a GTX 1650 or GTX 1660 would be more appropriate.
About choosing Linux distribution
I had hoped to install a Debian derivative distribution like Mint because since 2018 I have been using several Raspberry Pis (3B+, 4B and 5). The Raspberry Pi OS is based upon the Arm version of Debian Linux.
From 2002 to about 2012 I had been using Redhat and then Fedora Linux. For now Fedora Linux will be OK.
BTW
I realized that I had been converting the disks from MBR to GPT or GPT to MBR the hard way. I realized I had EaseUS Parition Master Pro. I used it to convert the disks from MBR to GPT. It completed both disks in less than 10 minutes without losing any data.
