Trying to install an OS from another laptop won't work due to OEM. However, you can get your files out using a linux distro (google). No need to install just run it off USB/DVD.

I have a Dell Inspiron N5110.
I have forgotten my password to access my computer. There is a guest account install, but I don't think I can do much from there.
I have tried booting up using the f8 method and clicking launch startup repair, but I get "windows failed to start 0xc000000f".
I'm assuming my laptop is too old and needs an update before it can open the launch startup repair.
Im looking into a method in which I download windows 7 Home Premium from a different laptop and install in through a USB, but my product key (which is printed on the back of my laptop) doesn't work (pre-installed software on this device).
I'm lost on what to do! I have lots of important files I want to recover
Please help
