Debian install DVD ISO images not working due to CD-ROM bug in installer

The iso image has been checksummed but I don't know how that would affect the fact that the installer is not recognizing it's own media location. How many images have you encountered that have failed md5 or sha? Seems like a weird angle for Russia to try to throw an election.

Latency is not an issue as I am using 2 Mesa 7i96 cards connected via ethernet. I really don't care where the drivers come from - all I would like ito do is increase resolution on the monitors. The default max resolution for linuxcnc's installers in way too low for my monitors.

The card is legit & not a knockoff as I've fully and successfully tested it using the Windows 10 drive that this system dual boots, along with linux.

With your experience, am I better off continuing to search for a working nVidia driver? Do those even exist for Debian 9 Stretch? Or would it make more sense to backup my home directory and reinstall a new, latest version of LinuxCNC with the nVidia card installed for the installer to discover?

One other issue - do you think that the Grub loader might be interfering with the installer? The installer doesn't even make it to the point of choosing the install partition. The CD-ROM requests comes first. Perhaps the live iso would be a better option for install.

Forgot to mention, disable UEFI, if the PC has it.
Backup your config, install Linux Mint and forget the headache. It has a driver manager so it will automatically recommend and install them.
With eth cards, it might work or it might not, that you will have to check. On a gaming PC ( i do not game ) i did make it work easily with Nvidia 1060/6GB and with an RX 580/8GB, the only issue was that after the first restart with the RX580 i got a black screen, restarted again and it worked properly with 4X 24" monitors turned verticaly with a resolution of 4800X1920.

Not that's what I'm talking about!! I boot from the Linux Live ISO burned to USB & it fills both monitors connected to the nVidia card at the correct resolutions. You just saved me weeks of reading. Mint it is! If the installer boot can figure all that out, I imagine it will probably be able to put an OS on this disk.

Thank you so much for the suggestion!

Appreciate this is an old thread, but I had the same problem so have included my agricultural work around in case others have similar.

Just after the installer stalls and cannot find the "CD", remove the USB (yes - not ideal) and insert in an alternative USB port. In my case the installer then prompted to install drivers, throws an error, but finds files and continues the install process successfully.

Hope this helps.
Cheers Pete

Thanks, too!
I had the same issue and solved it by using another USB port.

First it was on the back side and then it was on the top - works fine.

...still have the same problem, but I'm using an SD-card as a reader and don't have a second SD-card slot...

Any advise?
