Can not install LINUX CNC

Hi,
My name is Rui and iḿ new to linux CNC.
First time installing.
Iḿ trying to install in a old machine   INTEL Pentium D 940 3.2Ghz  with  2Gb RAM .
Graphic card is NVIDIA GEFORCE 7300 GS .
The machine as two discs 320 Gb and 160Gb , they are formatted .
I Download the 2.7.14 ISO the 2.8.0 ISO and the 2.8.2 ISO and Burn 3 DVD.
I can open the  LIVE CNC LINUX and use for example the Latency test and everything with in  the 3 DVD images  2.7.14 or 2.8.0 or 2.8.2 .
But when i try to install or graphical install, it starts reading the DVD and one minute after it freze and the monitor gets blank.
it happens with the 3 DVD images.
Any idea what iḿ doing wrong? Some very basic stupidity?
Any help is welcome
Below some information from the machine  with the 2.8.2 ISO live DVD.

Just try to install in a new machine RYZEN 5 16 Gb RAm and the ISO DVD 2.8.2 , works perfectly, just did not finished the installation because it is my PC for working with SUSE LINUX.
So i think that it may be something related to the hardware, maybe the processor 32 bit or 64 bit version? Or graphic card?, i will try to change the graphic card.
Regards,
Rui meirinho

Changed the graphic card to another, but  the same result.
Now i burned another ISO  he  ubuntu-10.04-linuxcnc3-i386.iso   and it is installed and working.
The processor is 32 bit ........
Is there any way to get a ISO from the new CNC inux in 32 bit?
Regards,
Rui Meirinho

Pentium D is a 64-bit processor, if I'm not mistaken? So that shouldn't be the problem?

Can you install the "vanilla" debian OS ? You could try for instance the 64-bit Debian 10 Xfce CD .

Edit: If the "vanilla" Debian 10 (Buster) install works, you should then be able to install linuxcnc and the Preempt-RT kernel by following these instructions.

Hi,
Just burned another ISO debian-live-10.10.0-amd64-xfce.iso.
Try to make graphical installation and the same thing happened, the DVD starts reading and about 1min after it stop and the screen goes blank .
The live Debian boots ok, and i can use the Debian from the DVD.
Some information from the Debian.

Trying to make the installation in non Graphical mode.
Now it is making the installation off the software but in non graphical mode.
It look that it is installing ok. 20 % 50% 80% 100% rebooting .
And it is booting the Debian 10.10.0 .
Now just need to o install linuxcnc and the Preempt-RT kernel .
Tomorrow i will continue and i will give news when finished.

Thanks,

Hi,
Just installed the new RT KERNEL

Hmm, try

sudo apt-key adv --keyserver hkps://keyserver.ubuntu.com --recv-key 3cb9fd148f374fef

The problem is discussed here: https://superuser.com/questions/1485213/gpg-cant-import-key-new-key-but-contains-no-user-id-skipped

 

Ah thank you Andy, the start of the installation is going well for me now, but it then blocks the installation of RTAI ?
