Nothing I have tried has allowed me to find out how to boot to a CD after an OS is installed. I've dug around for hours. Edited the .vmx file to add boot.Delay, etc. I figured maybe I could do it from the BIOS screen, but I can't even get into that. With all the pop-ups, or time to click into the window, etc., I cannot enter BIOS with a keystroke or call up a Bios Boot Screen. Ubuntu's boot menu is accessible but does not include removable media entries. I used to be able delay boot or boot directly into BIOS, but the options for boot are gutted from the GUI and VM > Power > Power On to Firmware goes to a black screen.
I have Ubuntu 20.04 installed in the VM and it boots fine. The .iso I'd like to boot is mounted and is set to connect at power on.
Of course all this is ridiculous because I guess the root password wasn't written down and the user account isn't in the sudoers file, so to get permissioned access is now not possible. Still, I don't understand why something that worked for years all of a sudden doesn't. It would be faster to just blow away the VM and re-install, but that really is not a viable "solution".
https://kb.vmware.com/s/article/1004129 is unhelpful.
This is a Linux installation of 17.5.0 on Mageia release 9 (Official) for x86_64. It's a fresh install. Nothing indicated install issues.
This VM didn't have problems when I was running Workstation 16.x.x, though I cannot say for sure I tried doing anything but going all the way into a graphical desktop.
