While you can theoretically install the hard drive in another laptop,
this doesn't always work out as well as the "Concensus" above would suggest.
Operating systems XP and later "Key" to the system on which they are installed
and hardware drivers aren't always the same or compatible from one machine
to another.
And even if it does "sorta" work such bastardized switchivers rarely work correctly.
Generally speaking what is best is to take the hard drive out of the dead computer
and install it into an appropriate USB hard drive enclosure and use another WORKING
SYSTEM extract your files off the drive as an external drive.
Though this is not your situation, even a failed hard drive is often not completely dead.
The operating system may be sufficiently corrupted to prevent it from operating any
computer, but the data is still there and visible & accessable to another operating system
on another computer.
