Hello,
I'm new to VirtualBox and trying to configure a CentOS VM on a Windows host. The first steps complete without any major issue but the 'Begin installation' buttom keeps being greyed out even after taking care of all warning triangles (see attached picture). KDUMP also seems greyed out but switching it between enable and disable doesn't make any difference. Any suggestion on what might be going on would be welcomed. Thanks.

Start the guest from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

If it's of any help, the image below shows the main settings from my working CentOS VM for comparison. This was installed a couple of months ago and; if I remember correctly, one of the main things I had to do to make the install complete successfully was to allocate 2 Processors (CPUs).

Hi @scottgus1,
I don't fully understand what you meant by "Start the guest from full normal shutdown, not save-state." In any case, I'm attaching the zipped log file. Thanks.

Hello,
What was I thinking? My fault: I had not realized of the scrolldown icon and had forgotten to input the root password. Sorry for wasting your time. Thanks.

No problem, glad it was an easy fix!

This is totally weird. I decided to go with a different ISO and started a new configuration from scratch. However, and after the initial steps, it took me back to the same situation as a few hours earlier: On the initial CentOS configuration menu, there is no scrolldown button (apparently it's not that I didn't see it earlier but that it doesn't show up for some reason) and no option to enter the root password and begin the installation. It's quite peculiar and I don't get why this is happening.

A prompt to enter the Root Password comes during the installation, not before it begins: See the CentOS Installation Guide: https://docs.centos.org/en-US/centos/in ... tallation/

After several tryouts, I noticed a couple of things: (1) the reason for the previous issue is that I was selecting a 'minimal install' instead of 'server with GUI'; (2) whether the prompt for the root password comes at the beginning of the installation or if it appears on the initial menu seems to depend on the ISO itself. After troubleshooting a few other things, the installation seems to be finally pushing through. Thanks!
