Can you be a little more specific about what you did ?
For instance did you re-install windows ?

Found this :

The first step is to determine which is the correct, functioning one. Boot the system and note the text that the boot menu offers you, or the order in which they are displayed (is the first one in the list the working copy or is it the second?)

Next, boot Windows to the working copy and follow these steps:

Open My Computer and choose Tools, Folder Options.
Click the View tab, place a check beside Show hidden files and folders, and click OK.
Open drive C and look for the file boot.ini.
Right-click boot.ini and choose Properties.
Clear the Read-only check box and click OK.
Click Start, All Programs, Accessories, Notepad.
In Notepad, open boot.ini from drive C. Look in the [operating systems] section. There should be two entries, one for each of the boot options offered by the boot menu.

Let's add some text to each one to help you better identify them during boot so you can verify which is working and which is not.
Click in the text that is enclosed in quotes and add a descriptor, like WORKS or DOESN'T WORK. Make sure you add this text somewhere inside the two quotes.
Save the file and restart the computer. At boot, choose the entry that includes WORKS in the operating system description.
If the system boots properly, you now know that the entry with DOESN'T WORK in its description is the one to delete. Open boot.ini in Notepad again, delete the entire line (it will probably start with the word multi or scsi), and save the file
Reboot to make sure the system boots normally.

[operating systems]
