Can I copy a bootable DVD to my hard disk for future burning to DVD? And
with the future disc, can I use it to boot my PC afterwards? Or do I need to make
the disc bootable again from the copied files by a third-party application like
Nero or Magic ISO Maker?
In this excerpt from
Answercast #22, I look at ISO files and explain how they are easily created and
managed with ImgBurn.
No, it’s very simple. This is exactly what ISO files are. They are complete images of the DVD, including the boot information that’s placed at the beginning.
That’s how operating systems like Ubuntu can be distributed. They’re distributed as ISO files which you then burn to a DVD or CD. Then you can just boot from those media.
Use the right software
That can do both sides of what it is you’re looking for:
- It can read a DVD and create from that DVD a single file (an .iso file) that contains everything on that DVD.
You can then save that; do whatever you like with it; archive it, whatever. But when the time comes:
- You can then again use ImgBurn to burn that ISO file back to a new blank DVD.
As a result, you’ll have a complete copy of the original DVD you started with. If that original DVD was bootable, then so will this one be.
Ripping protected DVDs
Now, there’s one exception I’m going to throw out here, just because I know that people often think of this: commercial video DVDs.
They often have copy protection on them. A simple tool like ImgBurn is not able to copy a commercial video DVD to an ISO file. Much less have that ISO file be usable for you to burn it back to a new blank DVD. You need to have special software to do that kind of thing – DVD-ripping software.
But for what you’re doing, for bootable data CDs, ImgBurn is the tool you want to use.
