Years ago I tried the Bart Builder for XP, but with a pre-installed XP and no installation discs it took for ever trying to search for valid XP installation files, and I finished up after many hours with build errors/warnings and ISOs that failed to boot.
I very recently had Windows 7 Ultimate installed as a second boot (via easyBCD) and W7 installation Discs so hope to have a much better experience with the PE Builder.
I have many years experience with XP, but unfortunately only 1.25 GB of RAM.
Windows 7 needs more than 1.25 GB and everything takes twice as long as XP,
assuming I can get over the UAC hurdles.
I assume that the PE Builder will run under XP and sweetly get all it needs from the W7 installation disc.
Please warn me of any potential problems.
