Burn ISO image


Hi,

I burned an iso image on a dvd.

I used (I believe) the command:
growisofs -dvd-compat -Z /dev/hdd=CentOS-5.0-x86_64-bin-DVD.iso

This iso wasn't burned to the dvd but the unzipped iso file (rpm's, release notes and so on). Is this correct or did I something wrong?

Johannes

That is the expected behavior. Surely this is what you wanted?

You should realize that the iso is not an archive (like zip). It is the filesystem containing, well, files. While the files can be archives, they don't have to be.

You can also mount an iso, like any other fs.

If you burned a distro iso, you can mount it like normal or boot from it.

I dont know if what you did is correct or not, as I am not familiar with fedora core but, you can save yourself sometime by using a program that has a GUI to burn DVD's and CD's

have you tried using K3b? Fedora uses the KDE desktop, I think you probably have this program already installed, check your K bar,(this is like the start menu in Windows XP).

then click on the program and you will have a nice graphical user interface program to use.

I hope this helps.

I expected one file on the dvd. Just one iso file. I have tried to burn it with k3b but only 7 mb was burned to the dvd. I'm now using Fedora Core 2. I want to buy this week a new pc and therefore I want to use a new distro.

Can I boot from this dvd?

well,
It seems strange to me that only 7mb got burned on the DVD, maybe you should check the integrity of your .iso,

have you ever burned an iso before? even a CD iso?

the reason why I am asking this is that sometimes when you burn an iso the computer wont see it as having 799 mb etc. it will sometimes say that it has 0 mb. the .iso is not seen as a file it is an image on the disk.

If you burned the iso correctly you should be able to boot off the DVD.

to make sure that there is nothing wrong with your DVD burner I would suggest you download a copy of knoppix and burn the live CD and test it out, if it works fine then your DVD should in theory be burned correctly as well.

I hope someone who has experience with Fedora pitches in they could your best help.

I have burned before but not an iso file. I have checked the downloaded is file with md5sum. The downloaded file is correct.

I shall try to boot from the burned dvd on my new pc. If it doesn't work I can do it again. Or otherwise with windows.

Why would you want it to do that?![quote] I have tried to burn it with k3b but only 7 mb was burned to the dvd.[quote]How did you know only 7MiB was burned? Does the DVD mount OK?

Makes sense... so this is a distro installation disk then is it?

Make sure you research all the HW before you buy. Here is your chance to go 100% compatible!

Won't know 'till you try

Note: if you take your FC2 install disk(s?) and stick them in the drive, you will not see a .iso file on them but a whole directory tree and everything.

If this is the fedora 7 dvd you are making, do an sha1sum on the iso and enter "linux mediacheck" at the boot: prompt when you boot it.

When you burn an ISO image to CD or DVD, you should see the contents of the ISO not the ISO file itself. If this is what you see, then you have done it correctly.

You should be able to boot off the DVD you created.

Ok, if you have never burned a .iso before then make sure you dont make the mistake that many people make. dont just get the .iso image and burn it on to the DVD like any normal file.

The way to correctly burn a .iso file onto a disk is to open up your preferred burning program and specify that you want to burn a disk image or a .iso, if you dont do this then your DVD will not work.

Which is exactly what the OP has done with the dvd-compat option for growisofs.

Do Md5sum on the iso. Go to k3b>Tools>Burn DVD Image>path/to/the/image>Burn. Check integrity of DVD before install.
