New Windows, same as the Old Windows
I recently got a new Acer laptop that came with Windows 7 installed. I usually use Linux, but I kept Windows installed for the sake of Netflix movies. All went well, until yesterday Windows committed suicide. It failed to boot itself, and then, in the process of the system recovery, trashed the bootloader and made the whole system unusable.
I promptly re-installed Ubuntu Linux using the entire disk, wiping out Windows. Good riddance!
