[SOLVED] Some DVD's do not boot on Z730-A PRO

[Ed Vaessen]

My question is why some DVD's do not boot, when yet a 'bootable' image is burnt on them. I use K3b on Linux. An image like OpenSuSE Leap 15.1 boots, an image like Ultimate Boot CD ubcd-x86-5.0.3 does not.

This is not unusual. DVDs can be finicky sometimes.
Could be down to the drive, the DVD, the burning process...

When I used to make DVDs like that, I generally used the slowest burning speed.

Thanks. Something for me to think about next time.

Found out: I have to set up the system to enable legacy boot. This boots into recovery media and setup CDs for older operating systems.
