URVIJ,

The error code 2000-0142 represents a failed hard drive and will need to be replaced. You will not be able to format and reinstall Windows on the drive.,

Okay, but can i get recovery of tht crashed hard drive data ? If yes, how ?

If the drive is still readable, you may be able to recover the data by mounting it in an external USB drive enclosure -- attach it to a working system and see what you can read.  If it's not readable (or that procedure fails) you'll need to consider whether the data is worth the cost of professional recovery.  There are many companies that specialize in data recovery and can retrieve data from even badly damaged drives.  However, the cost isn't insignificant -- it starts at around $600 and can easily escalate into four figures depending on what is needed to retrieve the data.

Like,

There are many different disk utilities that will create a recovery usb drive which will allow you to boot directly from the usb and do all kind of repair. Acronis Disk Director, AOMEI Partition Assistant and many more. Recovering files can also be done if the above utilities do not make the drive bootable. Sometimes the only problem is that the drive is fine but will not boot and you may get error indicating that the drive is bad when in fact there is corrupted boot record. You should first, before using any utilities get hold of windows installer on CD or USB and try the repair function that is part of the Windows installer.
