ISOs burned from 12.04 will not boot
Downloaded 12.10 i386 desktop iso from Ubuntu. Burned image per instructions on Ubuntu site for making bootable DVD. The DVD will not boot on a AMD dual processor system (AMD MPX 2000+ w/2GB memory & 72 GB of HD space on a SCSI HD system) with a Sony DRU-830A DVD/CD reader/writer. Tried to burn directly from prompts after inserting a blank DVD; Nautilis crashed every time I attempted this. Burned from K3b (my preferred burner) and the DVD would not boot. Burned from Brasero; same result. Not really surprised since I suspect these burner all use the same underlying software to actually burn the DVD. The DVDs will all boot on two other systems. I cannot ever remember having any issues with burning DVDs and booting on this system. As an alternative, I tried a Linux Format DVD (LXF 166). The computer boots to the live OS, I start the install process, but the installer crashes after I provide the user ID information (installer disappears and quits, and I can start the process again from the live OS. I have the same issue in making a bootable image for Linux Mint 13. I have made bootable CDs or DVDs for every version of Ubuntu starting with 9.04 and Linux Mint starting around 10. Now 12.10 will not boot. Very frustrated right now over not being able to install 12.10 or Mint 13 (Mint 14 requires PAE which is not supported on the system which will not boot the DVDs I'm making).
How do I get a bootable (and installable) version of 12.10?
Tonight I burned both ISOs on a different computer (running Ubuntu 12.04 LTS) and get the same results with regard to the DVDs not booting. My conclusion is the issue is not related to the computer on which I burn the DVDs but in the burn process.
Just burned the DVD using Windows 7 and the default MS burner. Same result. DVD will not boot.
