[Solved] Invalid Boot.ini Loading from C:\Windows Error

If while booting the computer in normal mode, you see this error message saying that “Invalid Boot.ini, loading from C:\Windows” then here is the solution to fix this error.

The error comes up while booting but after this the system boots normally as if there is no problem.

Cause of the error

The problem is caused due to missing or corrupted boot.ini file which is usually located in the C drive.


We can solve the problem by providing the same boot.ini file with correct properties.

1.    Right click on My Computer -> Advanced -> Startup and Recovery, click Settings.

2.    Now click on Edit button besides the line reading “To edit the startup options file manually, click Edit”.

3.    This will open the boot.ini file but if it isn’t there then click OK to create a new.

4.    Now copy and paste the following code in it

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP Professional” /fastdetect

5.    Click save and exit.

6.    A new file boot.ini will be created in the C drive, now we need to give it system attributes.

7.    Open command prompt (type cmd in Run box).

8.    Type the following command

attrib C:\boot.ini +s +h

and press Enter.

9.    The problem is fixed.

So just restart the computer to see the problem gone.

  11. Worked Great !  Lots of advice on this on-line but this solution was pretty easy to try.  To see if this file is even there you need to un-check the boxes etc so you can see these hidden and system files on C:/   It’s not in any folder, should just be sitting there, corrupted, or totally missing, on the C drive.  Anyway, this solution worked great for my Windows XP system, Home Edition, Version 2002, Service Pack 3.    This done April 16, 2012

    Been trying to fix this for a day. All other fixes needed boot disk. I’ve moved and have stuff in storage and can’t find it…

    I was so frustrated… I had to restore my computer TO GET ON THE WEB! Not anymore! It runs as mediocrely as it did before!

    My self described computer skills are akin to a blindman dusting items in a china shop with a basebasll bat!

    Many many thanks!!!
