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?
locate bootable OS on the pc. ( if more than one OS on the PC)
boot you preferred OS.
Login & go terminal as root.
usually most people prefer grub on "/dev/sda" but that's no always the case. So select the drive you prefer to install grub on.
run "grub-install /dev/sd?" change the "?" to the letter of the drive you wish to install grub on.
then run "update-grub" that should do it.
you could also run grub-mkconfig -o /boot/grub/grub.cfg
A. I always suggest installing "grub-customizer", this is a great graphical app to manage your grub. ie. update,add, change the OS boot order , backup & save grub. Even move to a different drive.
B. Supergrub disk or "RESCATUX" are incredible tools to carry around with you.
