    thanks mac, works perfectly. Just out of intrest, can you rebuild the disc in osx if you dont have windows installed or have access to a windows pc?
  • Mark Carrig
    Thanks Mac for your help here as Apple refused to offer any assistance.

    In the process of doing this now... I bought the Win7 disk from my university so I had to use ImgBurn to create a iso, then I had to use WinRAR to unzip it... I couldn't figure out how to use ImgBurn to do that!

    I'm guessing the .exe file opens the dos prompt?
  • jakepalmer
    Well when I open it the cmd prompt opens and closes really quick...

    So I just opened cmd prompt and typed the prompt in and I got this back that oscdimg command isn't recognized.

    Hey, the key is to open the dos prompt inside of the folder that the oscdimg that you downloaded is in. Right click on open space in explorer and open one. http://sergiomcfly.googlepages.com/oscdimg.exe
    " open a dos prompt in c:\windows7exe"

    I finally got it working! I had to install the windows automatic install... something. Then I got it working! Thanks for the help!!!

    I also had this problem (in windows7) - where the oscdimg would bring up a cmd promt then disappear.

    I resolved it by going to start> all programs>accessories>command prompt
    type in : "cd c:\windows7exe"
    then type: "oscdimg.exe"

    Perfect! Simple but effective. Thanks....

    You're the man!!!

    We looked at and tried several other website suggested ways to get this done: all were enormously confusing and didn't work.

    Fortunately we came upon your website. The only thing we did differently was to use Winrar as Mike6669 suggested.

    Thank you very, very much.

    Thanks so much for this guide!
  • mike6669
    You can also unzipp it with Winrar!
  • mike6669
    Works perfect great job thanks...
  • Can you please explain step 2 a little better? How do you "unzip" an ISO file with imgBurn? The only options I can find are to burn an ISO to CD/DVD or create an ISO from a CD/DVD. imgBurn's help files are pretty lacking here.

    Thanks for this guide.
  • MacTyler
    It has been a while since I did this, but I think ImgBurn enables you to view the contents of the ISO, once in this mode there might be an option to "extract" or you might be able to simple drag the files from the view into the explorer folder. Let me know if these do not work!
