Trying to Install Win7 7600 RTM 64Bit

Hello all i have a huge problem
I was trying to install windows 7 64-bit today over my 32-bit win7 RTM,but as you all know if you just insert cd and run it it wont work.
So ive tryed to boot it,but there comes the problem.
Ive changed my boot priority to CD-Rom but still my system gets booted from hard disk...
I really dont know what am i supposed to do anymore...

if anyone have the solution,plz help!

my motherboard is : Gigabyte GA-EP43-S3L

It appears that you are trying to boot a DVD that is not bootable... Re-burn your ISO as a disk image, at the slowest speed (4x).. do not extract the files .... After you do this, you should be ok...

Ah now i see!

Thanks a million :P

Ill try it out tommorow and see if it works,indeed ive extracted files from ISO first,and then burned them with Ashampoo's burner.

You will have to do a custom or clean install. You can not upgrade 32 bit to 64 bit

Yeah,i understand that,tho will i be able to same other partitions on my pc?

I mean if my OS is on C: will i be forced to defragment all other partitions?
