I recently discovered that running a Linux virtual machine is both cheap (RAM/CPU-wise) and easy; it seems like there's absolutely no need to have a dual-boot Windows/Linux machine (if this is not true - please tell me why!). That said, I would like to format my HDD's Linux partition and allocate that space to Windows. The only thing I'm worried about is the GRUB file, which (I assume) lives on the Linux partition, because I installed Linux second after Windows. Is it possible that by formatting the Linux partition I can damage the GRUB file and be unable to boot?
Details: Windows 7/Ubuntu 13.04 living on an SSD. When I turn on my computer the screen to choose an OS to boot to is the Ubuntu one (vivid purple color).
