I am currently trying “rodw” suggestion, I understand that the bata versions or in this case debian13 tend to be less stable than ones like 12 that have been out for awhile. They use them to have a larger sampling of users to identify bugs. It is an old tradition. However, I am trying all suggestions from more experienced linux users and sometimes the next release has fixed the bugs identified in earlier versions.
I did just check HP compatibility. I did not think it could be the problem but it is a good suggestion. My results were

"Linux will work on just about any PC. I mean that literally
It is totally possible to install Linux onto any HP laptop. Try going to the BIOS, by entering the F10 when booting up. In their, try disabling secure boot and switching from UEFI to Legacy BIOS then save your changes"

I will try the BIOS suggestions here but I do believe I have already done that a few times.
The latency test in live mode I will look into but I can't stress it out my system because I don't have it connected to a CNC system yet. I think my dedicated computer is at the high end of the linuxcnc requirements. Also this seem unlikely to be the cause of the issue of the system not finding an install on ether hard drive.

Please be respectful. I am new to Linux but as I understand from the last few days of learning Linux.. The "sudo commands" are used in a live or successfully installed version of Linux software. They are entered in what is called a terminal as a command prompt. User “rodw” would be better to ask about that he recommended I use some. The sudo commands I used in live mode seemed to be related to updating a repository of needed files that were not in the ISO install. Basic system queries like a file search.
Your last remarks were not clear, "buggy uefi and having to rename some boot files." If you have any question I can answer or if you have a suggestion to help solve my issue, I am happy to answer any question or try any possible solution. as always I do appreciate any useful comments.

Thanks John, that's what I thought. Yes, I noticed that the top menu items are the same on all tabs. That’s why I decided to ask you, since I wasn’t completely sure myself))))

Have to correct myself after reading through the QtPlasmaC documentation.
Centerpunch uses the spotter tool, which is the torch firing short enough to only make an indentation. Very clever. Has its own setting on the Parameter page, firing time most notably. So let the M3 $2 S1 stay.

Actually, when I think of it. I think its a bug/feature of PlasmaC that M3 won't allow a line above with only coordinates, but must include also the move command.
Not ok

Ok

I think one can not take for granted that EL3061's signal ground is the same potential as the workpiece ground. If you are lucky it might work, but to be on the safe side the torch signals should be isolated and free to float.

No the selection of the type of desktop has absolutely nothing to do with your issue. It only selects what kind of Desktop environment you will have once booted.
Grub is the boot loader, this is where your issue is.
Due to HP being in bed with MS they chose "Microsoft's way" on naming the boot files for uefi.

If you turn on legacy boot and disable secure boot, as tommy mentioned a while back this may resolve your problem.

Thanks for this answer.

I would like to install RTAI due to the jitter in my setup, which is around 70k.
I'm using 4 stepper motors with encoders (closed loop) and a USC board from PICO.

Sometimes, though not very often, I get an "Unexpected realtime delay" message.
Do you think this could be related to the jitter amount?

I've tried every optimization I could find in the BIOS...
 

Just having a look at the PICO config, is the base thread used ? From a quick look nothing appears to attach to the base thread. Which would lead me to think that a simple RT_PREEMPT kernel would be suffice. The PICO board would seem to operate in a simialr way to a mesa 7i90 using the EPP protocol. IE using the parallel port to send timing info to a FPGA.

I think that there are issues with https on the wiki, try http:
