CD/DCD reader/writer problem loading .iso disks

I have a dual operating system set-up, using Windows7 and Linux Ubuntu.
I am having problems running a number of cd-rom iso disks. Specifically, I want to load the iso disk, "GPARTED". This disk loads with no problems when I use Ubuntu as the op system. But with Windows7,
when the computer starts up, I hear the cd-reader/writer start up, the after approximately 1/2 minute the regular menu comes up on the screen.
Am I missing some setting or something?
Thank you

My apologies for not being more clear.
I am trying to boot off of it. There are some disk that load with no problems, such as Medal of Honor series, Microsoft Flight Sim, etc.
The disks that won't load seem to be the ones I burned from ISO downloads, GPARTED being just one of them.
I am wondering if they won't load because they were burned using a Linux burn program. If so, why?

Okay, I'll try that. I have some business to attend to, so won't be able to give the results until tomorrow.
Thanks for your replies, and wish me luck...

No joy...
Running Windows7, I downloaded a fresh copy of Ubuntu 13.10. Then I burned it to a dvd. The HP desktop just flat well ignores it. I checked the BIOS to make sure it was set correctly for reading from the CD/DVD and it was.
I then took the newly downloaded disk to my Dell laptop and it loaded immediately with zero problems.
I realize this is 99.99% not a Windows7 problem. But I have tried to solve this in a number of forums in the past. I am listing it here in case any of the readers know something about it.

Oh oh, you got me on that one. I haven't a clue as to what you are talking about.
I looked in my BIOS and there isn't any word with respect to "uefi" or "legacy".
Again, I am using Windows7.
Can you clarify a bit?

I can navigate the BIOS only with my keyboard.
