Yikes!

i would not do a mass copy of a single boot file to all systems unless you know for a fact that all of your systems boot.ini files are pointing to the same ide drive, channel, partition, and system folder!!

if, you get the path wrong in this line...

Code:

[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn


your computer will not boot!

since this is a INI file, read/writeprofilestring would be the way to go.
