bad install disc?

Verify the md5 checksums of your install CD.

Open a terminal to the path of your install CD and enter:

Code: Select all
md5sum --check md5sum.txt

You should get 1 failure on the md5sum.txt file itself. If there are any other failed sums or file read (input/output) errors then your install disc is bad.

If your install disc is bad then verify the md5sum of the iso you burned it from. If that's bad download it again. When you have a verified iso file try burning again at a lower speed.
When I verified the sum, it had multiple errors, suggesting that my install disc was bad. Ugh!

So I am wondering how to verify the sum of the iso I burned it from to know if it is bad?

Trying again to download.

If you are using k3b as your burn app, you can verify the md5 by:
1. After you have identied the image file to burn, allow k3b to compute the md5 (it will do this automatically). You can see the progress of the md5 computation at the bottom of the file selection window.
2. Check the "Verify Data" option.
3. Select a very slow speed for buring your iso file.
4. Initiate the burn sequence.
5. At the completion of the initial burn, k3b will close the session and momentarily eject the cd (dvd). It will then re-insert the cd and run the comparison between the image file md5 and the burned media md5.

If all is happy, k3b will return the "Success" status.

Hope this helps.

Thanks it was a bad download. I downloaded from a different source and that one worked flawlessly :)
