Creating a bootable ISO with dd
Hi folks,
i am trying to create a bootable W2K3 ISO image using dd. I have seen it mentioned that it is possible but all i can get is an iso image of the files, but it doesn't boot. This is the command i am using: dd if=/dev/cdrom of=/vmfs/volumes/w2k3ent.iso is there another option i need to add? if so i cannot seem to find it! Thank you for any advice you guys can give! Thanks Daniel |
Unless I'm mistaken "dd" stands for disk-dump. It just does a raw bit-dump from "if" to "of". I've avoided trying to use dd to create ISO images.
Try using mkisofs or genisoimage. :) |
Yes, you can copy a CD using the dd command. If the original CD is not bootable then the copy will not be either unless you add the boot code.
What application are you using to burn the CD image? |

i can't seem to make head nor tail or the mkisofs command, although i have read a bit about it and know it can make bootable ISO images. If i tell you where the CD is, and where i want it to go, would you be able to produce the required command? output: /vmfs/volumes input: /dev/cdrom filename: w2k3ENT.iso Do you need any other info? Thank you greatly for such a quick response! Dan |

I am not burning the image, just trying to host it on our SAN in order to use it to create VMs in VMware ESX 3.5 I have downloaded the boot.img file that i would use if i was burning using nero for example. Thanls for the reply! Dan |
try
dd if=/dev/cdrom of=/vmfs/volumes/w2k3ent.iso bs=2k make sure your source cd is already bootable.. |
