I am using ISO Master on Ubuntu Mate.
I want to create a modfied bootdisk using an MSDOS WIN98Noram_bootdisk.iso. Having added an executable file (SPINRITE.EXE) and removed some of the DOS application files I have saved the result to a new ISO file. I then burnt a new ISO CD using Brasero. An examination of that new CD and it’s source ISO file (using an archiver) shows they both contain the modifications I want.
However when I boot using that CD it cannot find SPINRITE.EXE and ‘dir / p’ shows the contents as per the original WIN98Noram_bootdisk.iso.
What am I missing here?
