I have heard that it's possible to alternately boot different OS's ( e.g. Win '98 and Win 2000 ) from the same PC disk . Is installation and running of this a simple affair or is it just going to cause all sorts of problems ? Am talking of an ASUS A7V/T'Bird 1GHz/IBM 30GB disk/Win '98 SE running smoothly . Are there any good guides on the Internet about this ?
