    Booting Windows 7 Breaks GRUB

    Every time I use GRUB to boot into Win7, I can't reboot back into GRUB or Windows. I think Windows is forcing itself into the MBR then proceeding to corrupt it. I believe I can just boot into a Live session use "sudo grub-install /dev/sda", but that seems like a lot of work just to reboot. Any suggestions?

    Windows has some software that writes into the MBR which is reserved for booting:

    In Windows 7, I had to remove Windows 7 DataSafe.
    HP ProtectTools, Dell Recovery, and a few others write into MBR meierfra.
