Re: ISO Images

its a Image file of CD/DVD you can burn this file to CD/DVD at once by clicking on it.

there are many software that supports this type of ISO creation and ISO burning.

well,in a simple case, you might not have access to a dvd, but still you want to transfer some files, then you can consider imaging. You can also directly copy it to your pen drive, but there's fear that some small files may not be copied fully. some may go missing or get corrupted. if you take an ISO image, such problems dont occur. This is in a crude level though.

The real application of image files lies in using a software or an application without actually using the dvd. There are softwares like poweISO, wherein, you can mount the ISO imge and use the software without actually using the disc. Let' say you buy a game and play it to such an extent that the dvd gets scratched badly. you dont want to use it again and again but you still want to play the game. then you can take an image of the disc and use it to play the game without the dvd. clear?:smile:
Remember, if you want to burn an .iso file into CD, you MUST use a specialized ISO burner software or the ISO function of a standard burner software. Just burning the .iso file directly would not extract its contents.

*durga feeling embrassed*

I did not do that part of it.
I direclty burned it using a normal burner.

aah!! since it is complete 'image' of a CD and not data by sectors , it needs to be put back on the CD on a same way!

I missed it 😔😒
Haha, it happens. I also did that mistake before 😉

What program did you use to burn? It should have an ISO burner feature

downloaded active ISO burner and burned the CD,
basically its fedora 10 😀 and I wanted to learn it.. so instead of changing the whole OS i downloaded the live CD of it.
So, it works now? 😀

I've only tried Fedora 9. Loved it!

mate!!

The fedora .iso file what i downloaded was corrupted.I could just see that welcome message and later it said failed to find x files, redirecting to shell prompt

now that i know what to do.. I will download one more version of it.

will try for ubuntu .
Ubuntu is recommended for its user friendliness 😀

... Big K is one of its biggest fans 😛

ok now

What's the difference between a live CD and a install?

If live cd can meet all the requirements of a install, then why dont computer comes with OS live CDs? a couple of them 😛

user can install which ever he wants.

and data on the drive should be accesible with both
😕

The difference basically is in the scope where each one is used.. Live CD is a preview of what you are about to load, and it can be used as a tool for recovery. If some boot loader files gets corrupted and if the OS wont boot, then live cd can be used to get it up and running. You can also use it to preview some new linux distro before installing it in your system.

That said, installed version always has more resources and more applications to use than the live cd version. As said before, it's just a preview.
Yep. Live CD's decompress all their programs into the RAM, so it may run slower than an installed system.

However, there are some Linux systems where you use the Live CD in conjunction with a USB drive that stores all your data and programs. That would be a better combination 😀 I think KNOPPIX does this.

ah! ok. so pluggin your USB drive and it should start up an new OS. That sounds even better than i live CD

thanks both of you! I got it 😀

Hey Folks,

The ISO image if available on your hard disk, install Daemon Tools Lite (Version 4.30.0 (which i have installed)). Now you can mount the ISO image by right clicking the Daemon lite tools icon. Once mounted, it is as if you have a CD mounted and you can explore the files available in the ISO.

On the other hand there are tools available to convert an entire directory/folder into an ISO image and Vice-Versa.

Yep, this is useful for installing software. You can create many virtual drives to mount ISO files. Of course, you can't install software that requires a clean boot 😛

I'm downloading Fedora 10 now. Looks awesome 😀
