Windows 7: Hard disk not recognized

i accidentally wiped my hard drive and recovery partion on an HP Pavillion G6 laptop running a 500 Gig seagate hard drive and now it will not recognize the drive.i can not format it or do anything please help.

Try checking your hard drive connection power and IDA or SATA.

Shut down your computer, Take the cover off now find your hard drive and check to see if the power,IDE,or SATA connection are good and snug.

If the problem still exists then repair MBR
Repairing the Master Boot Record
If you want to restore the master boot record, you can simply type in the following command in CMD:

bootrec /fixmbr

You can also write a new boot sector onto the system partition with this command (which is often more useful):

bootrec /fixboot

And of course, if you just use bootrec /? you’ll be able to see all the options.

Fixing the MBR and bootrecord doesn't retrieve the lost partition. What you need to do is recover the partition you erased in order to get the data back.

thanks but how do i get the command prompt if the thing has no operating system.would the original system restore disks solve this problem

To get to a command prompt, you can boot into the Recovery Console with the OS disc, which provides a command prompt. However, you don't need to do so for this issue.

ok will try this but earlier it told me no bootable device found and in the bios it does not recognize the hard drive either.

also could someonte tell me if the hard drive on this laptop is ide or sata

You could look up the specs on the laptop via the HP support website using the model or serial number on the bottom.
