Install on blank disk with no USB or DVD boot

Hi all, I bought an old pc with a broken HD but with a parallel port for my CNC ROuter project. If I can get the linuxcnc-2.8.0-buster.iso file onto the new disc I bought by putting into my normal PC I would need partitions so the ISO wasn't overwritten during the installation. Or could I just install LinuxCNC on that disc from the ISO image on the main disc? Not sure if any configuration would be wrong this way though?...Is there any advice anyone could point me to for this process? Apologies if its in this forum but I did a search without finding what I needed.
Many thanks in advance, Steve

- put the new drive in another PC that can boot from USB
- install as usuall
- take out the drive and put it in the old PC.

If you fancy a project and endless frustration, you could try pxe boot.

I do not recal any frustration using PXE Boot some 12 years back, but that was on a local network with a local server.
Over the internet though the main issue will be network driver support.
Still Debian should have 2 types of images for that, one is the bare minimum so stay away from it, use a bigger one.
I would think using another PC is easier, even borrowing or renting one for a day.
