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).

I tried to install windows 7 on my HP Pavillion DV9, but it's not booting from CD-ROM, i tried using a USB CD-ROM, but it's still not booting. pls I need assistance.


Hi,

Try to check if the windows 7 disc that you are using is not just an upgrade disc. Make sure that it is a bootable disc. Try to use other bootable disc to test. Also make sure that the boot device priority is set CD/DVD drive.

Hope this helps.

how to install windows 7 operating system


To Install the Windows 7 Operating System (Win 7 OS):

Instructions for a "Clean/New Windows 7 Installation:

AFTER BACKING ALL YOUR DATA THAT YOU DON"T WANT TO LOSE, Do the Following :

1) Insert your Genuine Windows 7 System Disc (Retail or OEM System Installation Disc).

2) Close down all programs and restart your computer.

3) As soon as the computer restarts, you should see a prompt that says something like this: "Press any key to boot from cd/dvd"

....So press any key!... This will boot to the installation disc and prepare for installation or repair (we are going to be installing windows, so ignore the repair options you see on the screen).

*If you don't press a key in time, you will see that the computer will attempt to boot from the hard disc drive instead... if that happens, restart the computer and press a key when prompted.

4) Depending on your particular Windows Version, you will see a prompt that says something about "Do you accept the license terms?" Click "Yes" or "I accept", etc.. and continue on...

5) Choos Custom or Advanced Settings (the other option is for an upgrade..)

6)Select the desired hard disc drive, (HDD aka Hard Drive), Select "Drive Options", and follow the onscreen instructions "Delete the partitions" (Do not Leave another windows installation on the same hard disc drive, unless you are experienced and know how to "dual-boot" properly!) Delete the Partitions.

7) Now choose to install windows (be sure to select the newly deleted empty (unformatted) partition. Windows 7 will automatically format the drive for you and will begin to install windows 7. Follow the onscreen instructions and within a half an hour or less (depending on your hardware) you will be finished, just be sure not to leave the computer unattended while performing a windows installation, since it requires your input quite often to proceed.

That's pretty much all there is to it!.. if you have any more trouble...
Google it or Bing it.... Search Engines are awesome!.... Enjoy!





*NOTE- If your windows 7 disc is a "Upgrade" disc, then you must perform an upgrade while running your previous/older windows version, since Windos Upgrade Discs aren't bootable, they simply patch the older version, replace system files, etc... to transform the previous windows installation into the target/newer version. If you want to perform a clean install, be sure you own a Windows 7 Installation / System Startup Disc.

You can repair that by booting your system using the CD ROM and the select to repair windows.

If ever this will not solve then;
You should backup your files and reinstall the windows operating system.

In installing operating system you need the following:

Boot your system any of this CD/DVD disc and then follow the on screen instruction.

After installation, don,t forget to install the drivers of your system that was enlosed in your system.
