I have got a pentium 4 pc that needs a OS (custom built) but it cant boot from cd rom, floppy or usb no matter what you do in bios(it will not respond you get a message "no operating system" or"no boot mgr"). I have tried with several hard disk drives but still it will not work. SO is it possible to use my vista laptop, crossover cable and a XP or Ubuntu cd to install the OS on the pentium 4 pc
