Upgrade to Windows 7 with clean install.

By Healer ·
When I have only a Windows 7 upgrade disc not a full version, am I supposed to have a previous edition, be it XP or Vista running before I can upgrade? What if I want a clean install? Can I still in the process choose custom install while using an upgrade disc and choose to format the partition or the hard disc?

Yes you can do a clean install of 7

You will/may however need a older Install Disc for either XP or Vista and insert that when prompted to allow the 7 install to work.

I would suggest wiping the HDD with something like Boot & Nuke


Or Kill Disc to wipe the current HDD


And have a clean unused HDD to install 7 to.

do a clean-install with a Windows 7 upgrade disc? Don't I need Vista installed and running and start the Windows 7 upgrade disc from Vista? Can I choose custom-install and have the hard disc wiped out in the process?

Well from my limited experience with 7

No you do not need Windows Vista or XP installed and running. Just set the Boot Order to Optical Drive first then HDD and insert the 7 Upgrade Disc in the DVD Drive and start the computer.

When you get the Press And Key to Boot From CD/DVD text press any key and follow the prompts. You'll be asked to insert an Older Install Disc which can even be a Upgrade Disc and when the 7 Installed sees this Disc it will proceed with the install of 7.

I would however first use one of the wiping utilities like Boot & Nuke


or Kill Disc


To wipe the HDD and kill everything on it just in case there is some kind of Infection that could survive a Format. Of course you'll need to backup all your Data before starting the wiping process.

According to what you are saying, I could slap my W95 disc into the player. Is that so? If, in addition, I could put any physical disc -- including an upgrade disc -- then, I spent too much for my W7 full-install. The upgrade disc was substantially cheaper ( ~ $200) compared to the full-install ( ~ $300).

Wouldn't the W7 at least investigate what was in the player?

win9x to win7 nope . . .

by Who Am I Really In reply to This is important to me

when the upgrade DVD looks at the HDD's and doesn't find a previous version of the OS
it will tell you what disc to put in


and I can guarantee you it will look at the win9x CD and say try again
with some sort of message stating something like

"Not a valid upgradeable OS"

Did you already buy -- and now have -- the "upgrade" disc?

Should say on the box, as I recall, that some version of Vista is assumed, since XP is not recommended as the base OS.

Right - you can't really "upgrade" XP.

What the installation will do is back up your entire XP installation and then install 7. No settings or anything are kept. But you could use the USMT. http://technet.microsoft.com/en-us/library/dd560801(WS.10).aspx

for the TecNet CDs. Information gone from the MS site forever is still on optical media. You know, for fans of archaic stuff, and those of us who tend to lag behind.
