Help installing iDeneb 10.5.7

[hab_hockey]

Ok so I have XP as my first partition and Windows 7 on another (both primary) but I want to install Mac over the Windows 7 partition (dual boot XP and Mac) so this is where my first question comes:

 

1. Do I format my Windows 7 partition or leave it and/or do I change the type (because it is NTFS)?

 

This is my laptop with all its specs: here

 

2. It has SSE2 but NOT SSE3 so I was wondering if I need a patch?

 

I've already downloaded iDeneb 10.5.7 and burned it to a dvd

 

When I restarted my computer and booted from the disc, I got to this screen:

 

 

 

 

and then a symbol came up (the circle with the diagonal line through it) and it just stayed there and wouldn't go into the installing screen. (the animated circle just kept going around)

 

 

I tried this 3 times and the no access sign thingy came up all 3 times.

 

 

So please help me fix my problem.

 

 

EDIT: I applied a the patch following a tutorial from this site: here

 

But one of the things I got was a bit different:

Some patch validation failed on mine so will it still work?
