Windows Installation Disc VS Windows Upgrade Disc -NOT THE SAME-
Having Trouble Booting To Your Windows Upgrade Disc?
...Upgrade discs aren't bootable discs. To repair a windows installation, you must use either a system repair disc or, better yet, a windows installation disc (genuine Retail/OEM discs are pretty much your only option to completely reinstall your windows operating system, unless you own a previous full installation disc of a previously released Windows version (such as XP or Vista), in which case you could install that windows operating system and then upgrade to a newer windows OS like windows 7. however if you ever need to reinstall windows 7, you would either need to reinstall the older windows OS, then upgrade to the newer one.
If that isn't clear, I'll sum it up....
Let's say you bought a computer, that computer had windows xp home edition. Maybe you wanted to upgrade from Windows XP/Windows Vista or Windows 7?
Well in order to switch from Windows XP/Vista to Windows 7, (or even from Windows 7 home premium- to windows7 Pro or Ultimate), then you must either:
A) Buy an upgrade disc and upgrade to the newer desired version.
B) Or, Buy a Retail Copy of the version you want to install. (keep in mind that a retail Windows 7 disc can be used to perform an upgrade rather than to competely wipe the hard disc and perform a clean install (delete partitions, reformat, and perform a new windows installation), if you so choose.
The bottom line is, you cannot Install a fresh clean copy of windows using an upgrade disc. OEM (Original Equipment Manufacturer) and Retail Windows Operation System Installation Setup Discs are "Bootable Discs". Windows Upgrade Discs are NOT bootable. (unless one where to "modify that particular disc, which is not legal).
