New to the forum and new to computer building in general. Is it currently possible to build a desktop or tower PC in which the OS is embedded and boots from ROM instead of booting from a mechanical drive? I want to use Windows 7 in 64 bit or MAC OS X in a dedicated purpose computer that will run only one program. The goal here is to decrease boot time and increase reliability for use by those who are not necessarily computer literate(musicians). Is there a version of Windows 7 in 64 bit available that could be built into the PC that would also allow "turning off" of some of the "bloatware" and unnecessary features that come with normal versions of Windows?
