Hi,

I have the same error code, but running chkdsk does not find any errors. Is this weird?

I too have experienced similar problem where for no reason our Dell Vostro 1510 laptop just stopped working without warning, no noises, no bumps, no spikes and no other significant identifiable reason to stop working.

Received the Blue Screen and after not being able to boot up in safe mode, or in safe mode with networking, or safe mode with command prompts.

The Blue Screen came up with :

error code : 0142

message error code : 2000-0142

message : harddrive 1 - self test unsuccessful = status 79

Another diagnostic message 

UNMOUNTABLE_BOOT_VOLUME

Also got error messages during diagnostics, however the above seem to be the common theme of many other peoples problems.

After trawling through countless forums and numerous google combinations seeking info on this issue, no one seemed to be able to offer a solution to get the machine operational to be able to save data.

This is what I did after piecing together snippets of info from multiple websites and hours of frustration.

Insert your OS disk into your cd/dvd drive

As the machine boots up - it should have an option to hit F2 or F12

Hit the F12 key

This will give you the option of where to boot your machine from.

Select boot from CD/DVD drive

For me windows loaded some files and gave me an option to either install windows or repair.

I selected repair

I was then asked for the admin password -- typed it in.

It brings you to a command prompt :

Type in CHKDSK

or

Type in CHKDSK/R

Hit the ENTER key

Once your machine has finished and repairing the hard drive, type EXIT and press ENTER to restart your laptop.

PRESTO THE STUPID DELL LAPTOP IS NOW BOOTING UP AND IS NOW HAVING ALL ITS DATA BACKED UP.

I have also found another command that could be tried if the above fails. Bear in mind, i didnt have to do it, but will post it here anyway.

After the command prompt - type in FIXBOOT

According to the DELL website the error code 2000-0142 is a Drive Self Test failed error code.http://support.dell.com/support/topi...ED2&doclang=en 

This has worked out for myself and i do hope it works for you.
