Windows Server 2008 – Creating Bootable ISO from CD contents

I recently downloaded Windows 2008 and I ended up with 1.76 GB worth of files you would typically see when you load the ISO or CD.  See screenshot below.  Unfortunately, burning a CD or ISO from the files shown below will not result in a bootable OS media.

I needed to convert this folder with files into a bootable ISO so that I can easily boot from it when installing Windows.  After some searching, I found that this can easily be done with CDImage.   I used the following command:


D:\Downloads>CDIMAGE.EXE -m -u2 -b”d:\Downloads\X86 VL\boot\” “d:\Do
wnloads\X86 VL” d:\Downloads\Windows2008_X68_VL.iso

      -u2 encode “UDF” file system without a mirror ISO-9660 file system
            (requires a UDF capable operating system to read the files)
      -m  ignore maximum image size of 681,984,000 bytes
       -b  “El Torito” boot sector file, no spaces
             (e.g. -bc:\location\cdboot.bin)

If you have specified the correct set of options, then you should see a ISO file generated in about 30 minutes.

Now off to configure my shiny new Win2k8 VPC….

    • just Install the Daemon Tools (daemon4301-lite.exe) file and mount the “.ISO” file it works as a Vertual Cd or Dvd Drive….

  4. Monish!

    Thank you so much! You have saved what little is left of my sanity (been doing IT for more than 20 years). Your solution was straight forward and elegant. Even when Microsoft stumbles upon an easy way to do something, they insist on screwing it up later. Installing Windows Server 2003 was not easy but at least you didn’t have to beat on the download just to get it to boot!

    Thanks Again!

  7. must be something i am doing wrong. actually i used the cdimage gui instead of command line. i will retry with the command line instead and see if that makes a difference. i am also wondering if i should reference the efisys.bin file instead of when creating the bootable iso.

    well hopefully i figure this thing own soon enough. thanks for the posting. this is a lot better than microsoft’s approach of downloading pfe software and the 20 steps it takes to produce a bootable rom.

  10. Hi Monish,

    Simple and straightforward , we need to copoy the exact command line mentioned by you , only need to change the drives. There is no space between -b and “…\” which is quite unusual. Works fine

    Thanks again

  11. Actually quite good, but there is some context to add. Please refer to the creation of a boot sector file via BBIE for mortals like me. And note that people wouldn’t need to use “in the sourceroot” if you don’t have spaces in the path to your source file, like when you are copying the actual DVD.
