My Toshiba satellite C55t C5300 got wet. I didn't know it & sent it in on a warranty repair because it kept telling me NO BOOTABLE DRIVE PLEASE INSERT DISC. Not a warranty issue they want to charge $419 to fix. I figured since it's dead anyway I'd attempt to fix it. The motherboard seems to be working so I'm gonna start by replacing the hard drive. Any help would be appreciated. Thank you.
