LinuxCNC install from USB

I am trying to install the LinuxCNC 2.8.0 Debian 10 Buster PREEMPT-RT ISO from USB. When it goes to install, it tries to detect and mount the cd-rom. I installed the LinuxCNC 2.8.0 Debian 7 Wheezy RTAI without this problem but want to use the latest version. Anyone else run into this issue and how do you overcome it?

NM figured it out. If you pull out the USB and mount it again then search for DVD it finds it. Odd install.

That seems to be the only solution so far, although i did install it several times and had no such issues a lot of members here reported that same issue.
Sorry for the late reply.

For whatever reason, I couldn't get it to install from USB at all (though I had previously installed 2.7 using USB). I ended up using a CDROM drive via USB. (Motherboard is a J3455B-ITX). Now reinstalling again after the system suddenly stopped booting to the GUI <sigh>.

go into the bios (f2 / F10 / delete)

change the boot order to usb first

I don't think that would have helped. It will boot from USB, but after starting the graphical installer from USB it can no longer find the install files from the USB.

Anyway, installing from CD worked.
