Installed Elementary via the live usb to D drive. C Drive is windows ssd. In boot order have changed so the D drive is higher in the boot order than C. When order is reversed, the C drive works as usual. When the D drive is first I get a 'no operating system found' message.
I've checked the checksum of the download and installed the usb as per the guide. Am installing whilst connected to a wired internet connection.
What setting do I need to change to get this to work? Have heard suggestion that it is a grub error, how then to install grub when I cannot access the operating system?
