Mac OS X cannot start up from this disk issue.

You are not installing onto the correct Drive.

You DID start up from the DVD. What is not working is that you told it to install onto "MacOS Base System" which is used to name the Recovery partition, the Installer, or the incoming Mac OS install image.

You should have Erased the boot drive AND created a Mac Volume there. Recent version of MacOS include new Volume setup in the ERASE function, but older MacOS DO NOT.

Initialize or Partition is a separate Required step, and includes a blank for you to specify the new Volume-name. default should be MacOS Extended (journaled) HFS+ (IF it asks).

The default name of Macintosh HD is not required, but MacOS Base System is prohibited, because it is already actively used for something else.

NO.

Not on THIS discussion, which is about a 2006 MacBook Pro installing far older MacOS.

That is too confusing for me. I am reading lots of different discussions at the same time and coming back after viewing 20 others.

You need to start a NEW discussion of your own, and post:

Your exact model-year Mac and screen size

Your last running MacOS.

What you are using to install {Recovery on disk, Internet Recovery after ten minutes of the spinning globe, USB-stick Installer, "live' inside macOS}

Also are you selling your Mac or trying to upgrade it?

I have posted my own but no one responded
