Hi,
That sort of boot disk is made by right clicking the A: drive and choosing
format. One of the options here is to create a boot disk. Or you can
download the necessary files from bootdisk.com. For a BIOS update, this is
generally all you need in addition to the file supplied by the motherboard
manufacturer.
You should be aware too that quite often now many of these can be done by
running a utility from within Windows. The methods vary by builder, so you
should check what the current procedure is for each.
Either of these methods has nothing to do with Vista, nor can they be used
to recover data or repair the operating system via command line in an NTFS
environment. If this is your boss's objective, then there are better tools
for that available.
