    Really what is going on is I have a cd-rom of WindowsXP Professional 
with SP2 and I want to put it on my cheap laptop from Compaq which came 
with Windows Vista which is Windows Melinium in character. It is so 
terrible I deleted it.

    Well now HP has told me the SATA hard drive has been giggered so you 
can't load anything but Vista. I told them I loaded Ubuntu Intrepid with 
no problems at all from the SATA hard drive.

    Then they let me d/l some strange software from the HP web page and 
I need to "remaster" the WinXP cd-rom with these drivers within. So I 
got the .iso easy with the gui Copy a disk. You then tell it to copy to 
a file and it does a fine job.

    The mount -o loop was found on Google and it works of course. But it 
has a problem(s) that prompted my message. The first is you can't add 
any files to the .iso because it complains. I can't find any way to make 
it a bit bigger. I think the added drivers are about 150 mb.

    What you say about getting the format right for the new cd-rom is a 
problem I do not know a thing about.
