I'm having a problem reimaging a MARS 50, keeps telling me there is no OS when booting from the DVD. I've checked the iso image file size, same as that on cisco.com, and I used the `make bootable' option on my Roxio DVD writer software. Also using DVD +RW and burnt at 4x.
At this point Im not sure if its the DVD writer, software or method I'm using, so I'm going to try another machine to burn another DVD.
Whilst I sort one out are there any other suggestions for points i may have missed?
Hashcalc is a free program that can calculate the MD5 checksums of your downloaded files. Compare that checksum with the checksum posted on CCO for the downloaded file. If the MD5 checksum doesn't match, your DVD image will not work properly.
Next, try a different DVD burning software program. If you aren't running Vista on your Windows machine, try burnatonce. It's 'donateware' and is free for non-commercial use. I've had good luck with using it to burn bootable DVD images.
