Windows 7 7048- making a bootable ISO

If you're burning the iso from Windows 7 beta (7000), just right click on
the iso image you downloaded, a context menu comes up, choose
'burn disc image'. (No extra disc burning software is necessary, Windows 7
beta includes this).

If the dvd you have inserted in the dvd drive is not empty, you will be
prompted to erase, the burn proceeds afterwards. I always check the
verify option to make sure the burn is good.

The option seen in the 7000 builds for burning iso images of any type is rather touchy if it works at all. CDBurnerXP is way too outdated to begin with while DeepBurner isn't actually that far behind it there either.

The most commonly used freeware is ImgBurn which is used to burn disk images only. The Official ImgBurn Website That's strictly a basic freeware with this type of burning in mind there.

Another much newer Vista ready as well as a late arrival for XP and offers a bit more seen in the free version then the above is called StarBurn that will run on the 64bit Windows as well as 32bit found at :: RocketDivision :: Free Windows iSCSI Target, Initiator and CD/DVD/Blu-Ray/HD-DVD Burner

I've been using that one for about 2yrs. already seeing reliable error free burns each time whether on XP, Vista, or 7. For the features it offers it is still far from the bloated retail products like Roxio and others.

I generally use StarBurn since that will run on the 64bit Windows as well as 32bit without a problem. That's already on the shopping list here along with a few other full version softwares. For the 32bit XP there are a vast number of free as well as retail products to choose from there.
