I need to burn a cd which I will boot from to reset a password on Windows Server.

I am using Active Password Changer, but I get an error like so:

enter image description here

How can I create a "DOS bootable disk"? I have an ISO on the cd I thought that will work. The manual says I need DOS system files, where do I get these from?

I am guessing that you are simply running the application from the download.

As for creating Dos boot disks, if you have a floppy drive still, simply format and choose the Copy system files option, then open up the disk and copy the password change application.

I would also highly recommend, they have a load of Dos and Windows bootdisks in a variety of formats that are ready to use.

If you go back to the Download Page you can download Bootable CD-ROM ISO Image (Password Reset Disk) which should just require burning and nothing else. To do this, use a tool such as CDBurnerXP (also available on Ninite for easy installation.)

May I also recommend Offline NT Password and Registry Editor, I have had a lot of success with it and it also comes in an easy to use ISO that you can burn straight to a disk.

I have no floppy drive. I have to do this with CD. – dotnetdev Jan 24 '10 at 20:10
If you have no floppy drive, you can create floppy image (ex. IMA file, with VirtualBox, VirtualPC ,etc). 1)Create a batch in Disk ISO, which mounts FDD image (from dos), using RawWrite utility. 2)Set that batch as boot file of ISO. – Searush Oct 22 '12 at 6:15

If you have the boot floppy, see this article on converting it to a boot CD:
How to Convert a Floppy Boot Disk to a CD Boot Disk
The idea is simply to copy all the floppy files to the CD.

If that proves too simple to work, see this article for a more complicated method:
Converting Bootable Floppy Disks into Bootable CD.
