How to burn a PC-compatible CD from .iso on a Mac?

    I have a slight problem with burning a bootable .iso image to a CD-R disk.

    I have a copy of Windows XP disk (legitimate, also own the license) and some time ago I made a copy of this disk into an .iso image file and stored away the original disk so that whenever I would need a reinstall I'd just burn the iso to a cheap CD-R and use that. Recently I acquired a MacbookPro for my own use and gave my old Thinkpad to my spouse to use. Due to a recent virus attack on the Thinkpad I thought it would be easiest to just reinstall XP on it so I grabbed a blank CD-R disk, popped it into my MBP, fired up Disk Utility, clicked Burn, selected the .iso and burned the disk. Straight-forward, right?

    Wrong - the disk won't boot in the PC, it's not even readable on the PC. What gives? What am I missing or how can I burn a CD on the Mac so that it would boot on a PC?

    As a workaround I installed XP from the same .iso into Virtualbox and burned the disk from inside that but I would prefer not to resort to such ass-backward methods just to make a PC-compatible CD. Any help would be appreciated, thank you :)

    What you did should have worked. I do it that way all the time for various Windows or Linux boot CDs that I keep iso files for. The only difference is that I have select the iso file before I click burn, but what you described may have just been mistyped.

    My first inclination is to blame your iso file, but if VirtualBox can boot it it's probably OK. I'm not sure what to tell you.

    Here's a how-to on burning iso files in Disk Utility. Maybe you're missing a step somewhere?

    I just did this the other day and it worked.

    If its already in .iso format, just burn it as a .cdr.

    If you want to make whatever it is into an iso for windows, convert the file to a .cdr in disk utility and then simply rename it with the .iso extension.
