So whenever I boot up the laptop, it instantly blue screens. I disabled the "restart on crash" option and found out the blue screen error was "unmountable_boot_volume." According to a quick cursory google search, this happens when the OS is unable to boot properly due to a corrupt hard drive.
Here are the things I've tried:
startup repair, the laptop restarts and then stays at the blue Windows 7 login screen with only the mouse cursor visible
reformatting with a Windows 7 installation disc, the installation always hangs at "Starting setup..."
running a memtest, no errors found
creating a system repair disc, repair stalls after I choose what language I want it to be in
running the proprietary system restore program, the program gets stuck on "loading, please wait"
running a chkdsk, no errors found
starting up in every type of Safe Mode, always ends in blue screen
I was able to boot with an Ubuntu disc and recover everything important but I can't actually boot it up with Windows without it blue screening instantly. I'm considering replacing the hard drive, but I might just buy a new laptop. If anyone has any advice, I'd be grateful. Thanks!
