Boot Device Not found

I have a hp tx2500z

When I turn on the power for computer there's a beeping noise coming from the hard drive I think and this message comes up in blue letters with a black background

" Boot Device Not Found

Please install an operating system on your hard disk.

Hard Drisk (XXX)

F2 System Diagnostics

For more information, please visit: www.hp.com/go/techcenter/startup"

When I run the system diagnostics for the Hard Disk Test, it says:
"Hard Disk Test Failed
Hard disk not exist"

What do I do? I went to the website but its suggesting that I basically may have to do a system recovery to the factory installed state...I have a lot of stuff I don't want to lose.

edit:
I also tried removing the hard drive and putting it back in, that didn't help either.

I called tech support and I still have my warrranty so I will be getting a Hp box to put my tablet in within a few days. But they told me I would most likely lose all the data I have saved.

Then I used a liveCD in hopes of backing up my harddrive but the liveCD won't even boot..unless im doing it wrong...( burn iso to CD, then load CD into laptop, and press f10? and/or turn on computer with CD inserted in and then let it load if it wants to?)

So what do I do?

thanks in advance

 

The drive is dead. There is no way to get the data off it except sending it to an (expensive) data recovery company.

 

double post

 

Why is it dead? I've used the tablet for less than a year. I bought it in late late late december-early january.

What might have caused it to die? Will moving the computer around while it is in sleep mode affect it? Or leaving it in sleep mode overnight?

and if this info is relevant. when I do turn on the computer, it makes a beeping kind of noise from the Hard Drive area

 

Yes, i read that. What you are hearing is the heads banging the edge of the case because they can't read the calibration data and they just move like crazy. Most drives fail in this way. When the computer is in sleep mode the drive is powered down as well, which means it shouldn't be any trouble.

Some drives just die. Notebook drives are subject to more physical shocks than desktop ones, so that's an extra factor, besides, HP mostly uses the cheaper Hitachi drives. I've had trouble with a Hitachi drive myself, on a Toshiba laptop, fortunately mine could still be saved.

If the noise you are hearing is a clicking kind of noise, the drive is 100% gone. If it's more of a "whirr" that goes up and down continuously, it has a chance of being recovered, but it involves voiding the drive's warranty so you won't get a free replacement.

 

So I guess I'll just send it in to HP since trying to recover any data from the dead HD may be super expensive right?

All those files....=/

Thanks

 

If there is no critical data you lost,send it to HP,and they'll give you a new one.
The WD HDD died in my notebook only after 3-4 months of using it,but got replaced for free because it was defective.
