problems burning pc knoppix image with mac os x

**uniflator** · 07-30-2003, 10:23 PM

Hello. As a favor I told my friend that I would help him rid himself of the festing horrible mess which is what we call windows. I downloaded knoppix (and some other distros) and am having trouble burning the image onto a cd.

Toast will not load the image and burn it as a bootable cd. When using the mount disc image option, I go utilities> mount disc image> and I then select the image. It does nothing. It literally sits there. (and yes I am using the most current version of toast. I have also tried an older version). What I have been doing is loading the image using disk copy and then either dragging the image into toast or selecting the contents of the mounted image and dragging them into the toast window. There is no blatant option of burning an iso 9960 so i select mac os and pc disc (hybrid) and burn away. The burns do not boot. Every time I get a "Operating system not found error."

I realized that it could be toast's fault and decided to try "blaze" which is a very straightforward cd burning app. It has a check box for iso 9960. I figured this was a good thing. I tried also loading the iso into it and asking it to burn an image. No good. So I've used the disc copy method I described earlier to attempt at burning a cd. No good. "Operating system not found." I burned a joilet cd just for fun and it didnt work.

I have tried burning at maximum and 4x speeds with different brands of cds. A few things I should mention are:

I did manage to burn a bootable knoppix cd using nero under windows when 2000 was loaded on it. I was able to load the iso into nero and burn away. This is the only 'good' cd I have. When I attempt to hd install there are a bunch of read errors off the cd. I have to restart.

I did upgrade the bios (the pc knoppix cd and the old red hat cd both ran before the bios update, and after). It seems in perfect working order.

I do have an ancient red hat cd that will boot. What most confuses me is the difference in a burn from mac to windows. This seems to be my issue. Of course, I'm not half as smart as half of you out there. But, can anyone try to shed some light on this for me? It's baffling.

Now when I boot up I'm getting the knoppix desktop but it shuts down when I hit ctrl+alt+F1 or just for fun after the os loads. This sucks.

Although I haven't burned a Knoppix ISO specifically, I'm pretty sure either Disk Copy or Toast can burn it. What you need to do is avoid mounting the image - mounting it read/write will probably add a hidden file or ten that will screw up the CD. Also, you should not burn a volume that is mounted from an ISO (on the desktop, etc) because it will only burn the partition you see in the Finder and not the ext2 or fat32 partitions that probably exist but are hidden from view.

Toast will burn an ISO if you choose Disk Image from the "Other" menu (the rightmost menu) and drag the .iso file to the window.

Disk Copy will burn the image if you choose the .iso file from File -> Burn Image...

If you had mounted the image previously you might want to get a 'clean' copy before trying a new burn.

If this is the way to burn .iso's in Macos then I'll add it to the FAQ. Why in the world would you need to dl a new image if you mounted the first one tho? That's exactly how you can test an .iso you've created- mount it, see if it works and then burn it to disc (at least in Linux). Does Macos do something to the .iso?

Indeed. You are the man. My problem was so simple. I didn't know the menu was there in toast. Thank you very much. F-ing gentoo keeps crashing on install, I'm trying mandrake right now. Thank you again.

Hi,
Well what i did useing mac os x was 1: Start up Disk Copy 2:goto the filemenu [image]--[burn image] 3:you pick the knoppix iso, it gets burned and thats what i did i hope it was helpful. Also i did it this way because i noticed that the format by just perparing the cd and dropping the contents of the iso made the disc in mac format. And i ran knoppix off of virtual pc to see if it worked and it did. Laters
