Toshiba Satellite A305-S6857 Not Working?

I was given a old Toshiba Satellite laptop that originally came with Windows Vista operating system and running wwith 4GB of RAM. However my friend who gave me the laptop said that it didn't boot up and that she tried to reinstall the software all over again with the recovery disk (2 discs) that she had with the laptop.

Upon inspection and turning on the computer, it couldn't boot up. Turning on the laptop I get the message....Bootmgr is missing.

So I tried to use the recovery discs that my friend game to me and booting first on the DVD drive, so I can restore the files like it was new. Upon installation it automatically stop and didn't install all the files....and then I get the message Recovery error: 10-FC09-01E7

I also tried installing Windows 7 full version since I have the disc. Upon installation I got the error BAD_POOL_HEADER with the blue screen of death.

I don't know what to do. I am running out of options. Could it be that this laptop's hard drive is bad and needs replacement. What steps can I do to check that the hard drive is not bad without the computer being able to boot up. Currently the computer just says Bootmgr is missing.. I tried installing a operating system but it failed.
