Linux copy

[easg]

I copied the linux red hat 9 cd 3 with nero, first I copied the entired cd to C: into a folder, the open nero and create the cd, but when I check the disk with the installation program the following message appears

"Unable to read the disk checksum from the primary volume descriptor. This probably means the disk was created without adding the checksum".

"No checksum information available, unable to verify media"

Will the disk work for the installation? or it is garbage?

How can I make a working copy?

Win XP
Nero Burning Rom

Thanks

It may be alright, but you can't be sure since the md5sum info is apparently missing. Try creating a disc image of the install CDs in Nero and burning the created disc images from nero. That should give you an exact duplicate of the original CD. I'm surprised you got your copied CD to boot. Bootable CDs must have certain info placed in specific areas of the CD in order to boot.

I installed the Linux without some of the option and It only ask me for the disk one and two, after this I select to add programs, and when linux ask for the cd 3 It read it fine, the problem is only during the installation of the OS, I booted the Pc with a floppy created with rawrite. I will create the cd again.

Thanks

I am having the same install issue, somewhat...

I am running WinXP and would like to be able to dual boot.

I downloaded the image files through my web browser and ftp and cannot get either to work.

I created the disks (1 thru 3) but cannot get the 1st cd to boot? I have the MD5SUM file, but have not done anything with it. Should I put it on the CDs?

I also am having an issue making the boot diskette. I tried using dos to copy it but apparently the bootdisk.img file is too big for the diskette.

Also, I have all the image files on a second hard drive in a partition by itself if that would open any other options.

Any suggestions? I appreciate anyones help in advance

You cann´t copy the iso files directly to the cd, you must use nero or some bunning utility to create the Cds from the iso images, for exaple, in Easy cd creator select files, create cd from cd image.
to create the boot disk use the rawrite utility.

C:\ d:
d:\ cd dosutils
d:\dosutils rawrite
enter disk image source file name: D:\images\bootdisk.img
enter target diskette drive: a:
please insert a formatted diskette into drive a: and press enter
d:\dosutils

Now reboot your pc with the boot disk

Thanks, It worked. Install went fine.

I copied the cd 3 of red hat 9 again first creating the iso image with nero an burning the image to the cd but the checksum error is output again from the media check utility.

any ideas?

[kingsucka]

did the first two cds work? Maybe the downloaded image is at fault. I had to download twice. First time with my browser and they didn't work. The second time I FTP'd them and they worked. That is about the only thing I can think of. Of course I am very new to Linux.

I still cannot get RH 9 to work with my ATI vc. dang it.

[easg]

No I don´t have the iso file, I´m copying from cd to cd.

[easg]

From the Linuxiso.org forum post me that I need to have the fresh iso file in orden to make copies of the cds check it out:

"The checksum is the code of a file or collection of files, that can be checked against original checksums to compare file contents.
Normally an ISO file has a checksum code in it, and carries it when burnt to disc. Your current method of trying to create a CD from another CD rather than an original Image file, is the reason your getting errors.
If you have broadband then grab some fresh ISO via ftp & burn some CD's.
If you dont then maybe a friend can help, or failing that buy some RH install discs."

I think this is a restriction for the linux distribution since no all of us have access to broadband internet, specially in the deveping countries, where linux is an exelent option and has all the doors open.

[easg]

Ups, I mean developing countries instead deveping countries

[kingsucka]

What country are you in? Maybe you can check with your local library. They might have a copy of Linux you can check out. Or they might have some other way to help you.

If you have linux installed already, you could use linux tools to get the md5sum of the cd you want to copy, copy the cd and then check the copied cd to make sure you have the same md5sum as the original. Check my post on linuxiso.org forum re using th rawread script to get accurate md5sums of cds:

http://www.linuxiso.org/forums/viewtopic.php?t=7456

Also, check out the link I cite there re some excellent info re creating accurate copies of linux install cds for redistribution.

Finally, the quote you referenced doesn't make a lot of sense to me. If your original cd has the md5sum info on it, the copied cd from the image should also have it one would think. I have some rh 9 cds that I burned from isos and will try a direct copy of one to see if I get any md5sum errors from the rh install routine.

[easg]

The original cds are ok, no errors during installation from them, the problem is with the copies made from them, make a copy from one cd, not the iso, let know the results, try to use a Windows xp PC and nero burning rom, if it is ok post me the steps you followed.

[Doobie]

Why not burn the CD with CLONECD and make an Exact copy of the cd.... The way you are doing the cd will not be bootable... but if you use clonecd it will be... being that the source is bootable of course....

[easg]

I have tried with the clonecd but it hangs at the 97 %, I´ll try again.

[easg]

Ok Nero 5.5.10.28 did it, I selected copy cd and then unchecked the "on the fly" option, checked the cd and it passed the test, maybe this is the only way to copy this cds.

Thanks you all
