he boot.ini file is on the system partition at the root of the drive, usually C:\boot.ini. However, it's a hidden file, which is probably why you can't see it. Perform the following steps to find the file:
1. Start a Command session (Start, Run, cmd.exe).
2. Type the following command (ah stands for "attribute hidden"):
3. You should see the boot.ini file. If you can't find the file on the root of the C drive, you might have some boot software installed or the C drive isn't the active partition. Check the root of each drive with the dir /ah command.
To remove the hidden attribute from the boot.ini file, type the following command from a Command session:
attrib c:\boot.ini -s -h -r
This command removes the system (s), hidden (h), and read-only (r) flags. You must remove the system attribute to remove the hidden attribute. Now, you can modify the file. After you've modified it, you should reset the attributes:
attrib c:\boot.ini +s +h +r
