I am not that savvy with Macintosh computers so I can't figure out why the install disk keeps ejecting when I attempt to boot from disk by holding down the "C" button or the option button.
It is not the optical drive as I was able to boot into Linux using a live CD.
While in Linux I formatted the hard drive I want to install the OS onto as HFS+ and had no problems.
I think I may be using the wrong installation disk since I can't confirm this disk belongs to this machine.
The disc reads:
MAC PRO
MAC OS X INSTALL DVD
VERSION 10.6.2
DISC VERSION 1.0
2009 APPLE INC.
Computer identifies as:
A1186 MAC PRO 2.66QX/2X512/7300GT
How can I determine if this is the right disc and/or which is the latest retail disk I can use on this machine?
UPDATE: Thank you to everyone who took the time to answer. From what I am understanding from the responses collectively is that determining which install disk came with my machine is going to be not as straightforward as I thought. Second regardless of what I choose to do I would need to start with Snow Leopard first and then work my way up. I was thinking the along the same lines as in I probably dont have the right disk.
Since I posted this question I have been on the phone with Apple Support as Bmike had suggested for an unbelievable amount of time. The customer service rep was a nice guy I felt that he wanted to help but was ultimately not well versed with apple products from this time period. He told me that the disc I have isn't model specific and that any disc should work, he didnt seem to worried about weather it was the correct one. Also I gave him the serial number and despite this he could not tell me what specific disk I would need to boot, instead he focused on getting the machine to boot with the disc I had on hand. We tried every possible keyboard combination while booting, booting while connected to a network via ethernet, resetting the svram, nothing worked. He ultimately set me up with an appointment to an Authorized Service Center. I am not sure if I will go as I dont want to explain everything and spend time just so that the genius bar can conclude the same thing or worse tell me that this model is no longer supported (which is the most annoying statement) its like taking a 2009 Prius in for service and Toyota saying oh man sorry bro that model has been discontinued we only meant for you to buy our super expensive computer to use for 100k miles then we expect you to trash it and buy another one.
I was lucky to find another drive from another MAC PRO that has the operating system on it and I plugged it into the computer in question and it booted just fine. So before I try and get my hands on Snow Leopard, I am going to attempt to clone the bootable drive and hope that the clone will boot without any issues. Problem is that the bootable drive is 2TB and I only have 250 GB drive as a target drive, so I plan to shrink the partition on the bootable drive and then clone it to the smaller drive that would have the same partition structure. I have never done this and I know its harder than I am making it seem, can anyone give me any tips or advice on how to do this correctly? I read somewhere that I might have to change the blocksize, true? I am planning on using Clonezilla.
Sorry I typed way too much.

According to everymac.com, your Mac is a 2006 model which was discontinued January 8, 2008. (I made the assumption 2.66QX means 2.66 GHz Quad Core Xeon) This model originally was designed to run OS X 10.4.7. Since the Mac OS X v10.6.2 Update is dated Nov 9, 2009, I doubt the disc you have is the correct one for this model Mac.
The OS X 10.7.5 (Lion) was the last version designed for your Mac model.
If you were to purchase Lion from Apple, then a requirement to install would be to have Snow Leopard already installed. In other words, the DMG file only offers an upgrade to Lion. You probably can not use the DMG file to create a bootable installer. You can read the requirements from the Apple Lion website given in the above link.
You would not need a Apple ID to install Snow Leopard, but the installer will still ask. You can decline to give an Apple ID if you wish. Snow Leopard was released on a DL DVD. Apple still sells Snow Leopard DVDs, but you can also download an ISO from the internet. Instructions are given below for creating a Snow Leopard USB flash drive installer. If you chose to burn a DVD, then you will need a DL DVD, since the contents of the ISO is over 4.7 GB.
Once you have Snow Leopard installed, you should install all the available Snow Leopard updates. This would update Snow Leopard to OS X 10.6.8. From here, you could upgrade to Lion by using a purchased DMG file.
Creating a USB Flash Drive Installer from a Snow Leopard ISO File.
This was done use an iMac (21.5-inch, Mid 2011) 2.5 GHz Intel Core i5 with MacOS High Sierra 10.13.6 installed. The flash drive was testing using VirtualBox Version Version 5.2.26 r128414 (Qt5.6.3). The flash drive needs to be at least 8 GB in size.
Use the Disk Utility application to erase the flash drive, as shown below. I chose the default name
Untitled. Finally, click on theErasebutton.Highlight the name
Untitled, then click on theRestorebutton on the top of the Disk Utility application window. In the popup window, select restore fromMac OS X Install DVD, as shown below. Finally, click on theRestorebutton in the popup window.The flash drive was tested using Virtual Box. Other than selecting the flash drive, I used the default settings for a 64 bit Snow Leopard installation. After booting from the flash drive, you need to use the Disk Utility application to erase the internal drive before installing Snow Leopard. Basically, select the setting shown below, then click on the
Erase...button.The result is shown below. Make sure the partition map scheme is
GUID Partition Table.Return to the Mac OS Installer and choose to install to the
Macintosh HDdisk.When the installer finishes you should get a Welcome window similar to what is shown below.
The result after answering all the questions is shown below. I selected
