How to Remove a Second Windows 7 Operating System

01/05/2010 12:00 AM

I have purchased new Dell laptop inspiron 1545(windows 7) within the week unnecessarily I have reinstalled the window operating system. Now whenever restarting the laptop in the beginning I needs to select the operating system. Because there is two windows 7 operating system one is factory setting and next one I installed. Now I like to uninstall which I have installed.

How can I remove second installation?

Advise please

Reinstall it again and un-install the former O/S's during the process or enter Dell setup and designate the default O/S.

Since it is new, why dont you format the system and install a fresh OS. By this you can also clear your registry entries.

If you have created a restore CD, use this to restore the system to the factory settings.

OR

Got to system properties and select the operating system to be selected at startup and set the time as 0 sec. By this way you will not get the OS selection screen at startup. Also you need not delete your second installation of Windows 7.

try system restore, too. I think that would be quicker.

I think system restore is O/S specific, I don't see it being effective towards the OP's question

I see.

looks like OP mistakenly created another partition for the 2nd OS. will deleting that partition work as well?

BTW, your answer should not be OT.

Sure...at this point reinstalling and reformatting everything prior to repartitioning is optimal.

I hope that you have installed Ok but during installation forgot some point.

You can change it from DeskTop > mycomputer > Rt-click > properties > Advanced > Startup..Tab:

Change in Default Operating system [This is in XP ]

or

edit boot.ini file in root-directory:

Be careful to edit it.

There is no boot.ini in Windows 7. See my post below.

Download EasyBCD here:

http://neosmart.net/dl.php?id=1

Boot onto the OS you want to keep (I'm assuming the first one). Run EasyBCD and make a note of the path of the second OS. Delete this folder (or rename if you're nervous). Click on "Add/Remove Entries", click on the entry you want to delete, then click the "Delete" button. Then click the "Save" button. Reboot. It should be gone.
