My os got corrupted and I installed the same os in different drive . My problem is that when I boot the system two os are displayed one is corrupted and another is which I had installed in another drive . Now how shall I remove the corrupted one from my startup screen:(

On your original boot drive is a file called "boot.ini" It's hidden, so make sure that you can view hidden files and folders. It may also be tagged system and/or read-only. The easiest way is to get at it from the run prompt. Click Start/Run. Inside the window type the following: attrib -r -h -s c:\boot.ini

Click OK. Cut and paste the command in the window to make sure you've got it right. Spelling and spaces count!

Now click Start/Run again and type the following: notepad c:\boot.ini
Click OK. Again, cut and paste to make sure you get it right. In the file you will see the following line:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=... blah blah

We're only concerned with the first part. If the first part looks like what I posted, delete the line and you'll no longer see it on your startup screen.

Save the file and exit notepad.

BTW: screw this up, and you're toast. Follow the instructions VERY CAREFULLY. If at any point, something doesn't work. STOP! And ask questions!

Yes editing your boot.ini is a valid idea, but this may cause you more problems.
Best advice is to back up EVERYTHING you want to keep and start over with a FULL reformat install.

I agree with Ben here for the following reason. If you installed the new version on a different partition and you remove booting to the old partition then you will loose all the space on the old partition. Better to do a fresh install of Windows on the old partition and remove the one the new partition.

Agree with Curlyben and ScottGem, but I also have a suggestion: You may want to try "Gparted", it's an open source graphic disk partitioner. Reformatting the drive where you have the bad Windoze install without altering or deleting the good install it will be a breeze. I have used Gparted for a year now and never had a problem. You can also resize partitions and change file systems with it.

While you're all correct as to how 04091985 should remove the old installation, don't forget that he/she may have data or programs in that old installation that they may still be using. Deleting that installation without recovering the data could be disastrous to the user. I answered the question as asked. Ideally the user should consult an expert and get his system straightened out.

Slog,
We weren't criticizing your answer. So far, the answers I've seen from you are very good and allow me to welcome you aboard. I just wanted to point out that Ben did mention and emphasize backing up everything.

C I will tell you one thing its not the matter of re-installing it's the matter of learning and saving time . So that's the reason why I asked you people thanks for your comments and it was more useful for me also Thank u Everyone:)

If you wanted to save time, you should have asked before you made the mistake of installing into a new partition.

All right sorry about that
