Tried every net solution for days to install linuxcnc

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.

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.

I thought this install page was just for desktop cosmetic stuff, but it also has "standard system utilities" as a checked default. I am just trying to be sure how important these settings are.
"Grub is the boot loader, this is where your issue is." Do you think the Grub boot loader was not in any of the ISO installs I tried? If so, why would it be left out since it is required to to have a successful install? Are you saying that if the Grub boot loader was left out, it would prevent my system from detecting any hard drive with a successful installation?

Do you feel that HP is preventing Linux software from installing?

"If you turn on legacy boot and disable secure boot, as tommy mentioned a while back this may resolve your problem."
I did try this suggestion before I joined this forum. It is a good suggestion offered on the net. I will keep trying every setting because I get suggestions to try this setting in different ways,

To say Trixie is unreliable is untrue, particularly when it now an alpha release. The reason why Trixie was recommended is that it has a current version of Linuxcnc in its repos and you may have needed later drivers. The reason why I said to use XFCE or mate is that these are Xorg  based desktops which Linuxcnc requires. Wayland desktops are problematic for Linuxcnc.

But when you see the messages about Realtek, this is because you do not have a useable HDD and the system is looking to boot off the network somewhere through the Realtek network interface. You don't wnt this.

The sad part about your issues is that it is due to you not having a suitable HDD/SSD installed on your system, My recommendation would be to go and buy a new SSD and install that in your PC as clearly something is wrong.

I don't know why you think you need to update repos. They are setup by the installer to point to the correct repos. I have never seen this mentioned nor have I ever had to do this. The only time you may have to do is when installing a distro that is EOL. That will need to done after booting into the system for the first time.
No I know that grub has not been "left out" I've installed the Linuxcnc iso a number of times. Rod & the guys do a very good & thorough job on, and the guy that does the RPi images has half a brain as well.
From a simple 2 minute search, it would appear HP uefi boot files that uses bootfile names that are tied to some microsoft naming convention. This is not the generally excepted method. There are some guides, search hp whateverhpmodelimusing linux install issues or something along those lines.
To correct the issue you will have to do a complete install, boot with systemrescue cd open a terminal and make the changes. I'd urge you to read the docs relating to the systemrescue cd.

I totally understand and agree. I didn't know debian13 was out of Bata and now an alpha release. It is good to know that Trixie/Debian13 has Linuxcnc as part of its repos. Also "XFCE or mate is that these are Xorg based desktops which Linuxcnc requires" is very helpful knowledge. Your comments about Realtek makes a lot of sense.

The installation of Trixie/Debian13 was also successful but would not reboot, But I now think you are right about my HDD being the problem all along. It did not pass the "short test" and I found this on the net, "Yes, a faulty disk drive could potentially install a complete operating system but then not be found on reboot" It seemed to weird that all the ISOs I tried would have the same error once they were successfully installed. I am now swapping out the HDD with another one I have, so I can hopefully get Trixie/Debian13/Linuxcnc on the main internal hard drive. I was going to do a bootable USB drive and run it in live mode set to "persist" the settings I made, but that would be slower with the USB bottleneck. Thanks again for everyone's help, I feel this action will solve the mystery issue. I will get back to you all with the conformation if or when it works.

You don't need the system connected to a cnc machine to stress it. The docs clearly state what is the recommended way to stress your machine. Yes I do recommend RTM.

Just to be clear, are you attempting to use a desktop or a laptop, some searches on the model in the jpeg come up as a laptop other come up as a desktop.
Laptops, apart from from some Thinkpads Tommy has tested, are unsuitable for Linuxcnc.

Thanks for all your suggestions, I believe my issue has been solved (see my last post) I hope to confirm the solution worked after I install to the newer hard drive.

See once again completely ignoring a simple question. Do you have learning difficulties ? Or some other condition that prevents you from giving information ?

Honestly I don't care, you've been one of the most frustrating people lately, and that's saying something considering we had another numbnut insisting there were packages contained in the RPi images that were never meant to be installed.

I know I'm in breach of CoC but you're in breach in being a reasonable human, shame the tranzes didn't think of that when they were playing Gestapo.

Please be respectful, you can be helpful without being insulting. I am on a desktop. I didn't see the ??? and thought it may be a rhetorical comment. In any case the point is moot. I believe the solution has been found. See last post. Thank you again for your help.
