Ntldr missing from Active drive.

Hello,

You have not mentioned the Operating system you are using. I am giving you a solution assuming that you are using Win XP.

There are two ways to fix this issue.
1. You need to extract this file from the CD and than copy into the root directory.
2. You can run a repair of the Win XP using the disk.

The second option is the better and the easy one. I have provided the link below where you have step by step instructions for the same with screen shots.

Hope this helps.
