    My Dell Inspiron 1420 went blue screen then boot with the word ‘error loading operating system.’ Did the diagnostic thing using dell’s recovery cd and it say error code 0142. Tried to repair windows but it says don’t have compatible OS. After fixing the Windows registry errors as you suggested, now my computer is running smoothly without problems.

    I have a Dell Inspiron 1525 Laptop and it is out of warranty period. It was working fine till it failed to boot with a blue screen. I ran the diagnostics tool and it read an error code 2000 – 0142, Hard drive 1 – self test unsuccessful status :79. I contacted dell technical support and they told me that my hard drive has to be replaced which i didn’t want to do since my laptop is out of warranty and it would cost me around Rs.14000. I was very glad to find your post here telling me detailed information to solve it.
