I have successfully installed Debian on various machines over the years. But my most recent attempt has been less than stellar. The machine is a refurbished HP desktop Product No. E4F35UC#ABA which came with Windows 10 pre-installed. The machine type itself may not be the problem because I have installed Debian without difficulty on such machines in the past.
I tried i386 and AMD64 10.7.0 three-DVD sets, i386 and AMD64 10.7.0 netinstall single DVDs, AMD64 10.0.0 three-DVD set, and i386 and AMD64 10.0.0 netinstall single DVDs. None of them would even boot.
I tried an i386 10.0.0 three-DVD set and it went through the entire install process but, upon reboot, it stalled at "Started Gnome".
I tried just the first DVD of that set and the base system was successfully installed and ran properly, but I don't know anywhere enough about Linux to try to construct a full Gnome system on top of the bare base.
I tried Live DVDs and USB sticks, all with similar failures. I even tried Clonezilla and even a straight dd from an existing working 10.7.0 system, but I really don't know enough about Linux to make them work either.
I finally got an i386 8.3.0 netinstall DVD to complete properly and Gnome is now running properly. 8.3.0 will be sufficient for what I want to do with this machine, so I'm tempted to just leave well-enough alone.
EXCEPT, the system rejects the root password I used during installation, AND, in my user account, sudo is not recognized as an existing command. PHOOEY !!!
I only paid $90 for this [paperweight] [doorstop] ahem, computer and drop-kicking it is becoming a more-and-more viable possibility.
Any final suggestions before I give up and start over [I HATE losing].
