rename it to .iso and burn it as you would an .iso file.

Yes, it matters.  See http://windows.microsoft.com/en-US/windows-vista/32-bit-and-64-bit-Windows-frequently-asked-questions for info.

for one: 32 bit windows can't be upgraded to 64 bit windows. You'll need to do a clean (non-upgrading) installation if you want to get 64 bit windows on your computer.

1. Follow the instructions from this link ...., tells you how to rename a file's extensions so you can change your.img to .iso.

2. try rebooting your pc to your newly burnt cd and see if it bootup to the cd normally and goes straight to the setup and its instructions for you.

right-click on the file and rename.
Then burn it to cd using an iso burner (http://www.petri.co.il/how_to_write_iso_files_to_cd.htm)
