I'm trying something similar and encountering a problem. I want to back up my notebook with Ghost32.exe (Ghost 8.0) from a WinPE session but writing the image directly to the usb external DVD writer is not supported. ... so I boot WinPE, run Ghost32, dump the image to a USB external hdd (4-2GB files), and would like to transfer 2 per single layer DVD. I want to put the WinPE and Ghost32.exe on the first disk so it will boot and run from RAM drive, run Ghost32 and restore the image, one disk at a time until finished.
The problem is that, even though the WinPE is bootable on CD, when I write it to DVD it is not. I used the WinPE utility oscdimg.exe to create an ISO (with -m option to write an .iso larger than 700mB). It works on CD (without the Ghost files), boots and runs. ... but when I burn the same .iso image to DVD (both using Nero 6) it will not boot but I can see and read all files.
What am I doing wrong or not doing?
