Long Delay loading Windows 7 install disc

Confusion. Are you installing Windows 7? If so, why are you burning a disk?

Or are you trying to do a repair from the install disk? Still, why are you burning a disk?

Or are you reformatting your pc for a new install?

For the burning confusion; I tried to burn a file on a DVD, that's when I noticed the high-pitch problem, to make it simple: I have several problems.
1. My DVD-drive makes a very high-pitch sound, though it's only 2 months old.
2. My DVD-drive takes a lot amount of time to load the described menus.
3. My Harddisk is slow, though it's a problem I can solve by formatting (which I did).
My setup is 2 months old.

This is how i found out.
Problem 1. I was burning a random ISO file.
Problem 2. When I did the reformat for problem 3, and when I booted from the disc again to see, if the problem had disappeared.
Problem 3. My Harddisk was taking insanely amount of time to open various programs.

Hope this cleared some stuff up for you
And I hope you will assist me further.

Edit: When I was burning the ISO in ImgBurner, it was unable to finish.

It sounds like a nice setup. Your dvd drive is probably failing. The high-pitched sound, along with burning problems would indicate this. Since it's two-months old, I would RMA the drive. Bad hardware never gets better.
