The only Symantec app I have is my genuine Ghost 2003. When I've updated it (some years ago now), I've done it incrementally, using Symantec's archive server. As you and others have confirmed, it normally requires two iterations to arrive at Build 793. At present, I've just the one bootdisk (floppy), which I've used a fair amount and which I guess will eventually develop errors.

As I see it, I've a distinct choice at the moment for ending up with some Ghost bootdisks (floppies) that I'll be able to use over a number of years into the future - either (i) get some new, good-quality floppies and make several bootdisks from my Ghost 2003 Build 793 on this current-and-soon-to-be-ditched machine, or (ii) when I've built my new machine (still using WinXP), reinstall Ghost 2003 on it, update it to 793, then make some new bootdisks. Clearly, the more sensible thing to do would be for me to make the new bootdisks now. With (i), I wouldn't then need to even install Ghost 2003 on the new machine.

If I use one of the Ghost switches when making the bootdisk, I can even make it compatible with Win7, if later I decided to upgrade to that OS. I'm presuming that that switch is universal and isn't specific to Win7.

What I'll do is make a few copies of two new versions of the bootdisk - some with the switch (to use specifically with Win7) and some without the switch (to use with WinXP 32-bit).
