To clarify based on comments below, I installed Windows onto a new disk and now I want to be able to boot from that disk using gGrub installed on a different disk. Do I need to change the way I install Windows, or do I need to do something clever with grub?
I have Windows 7 and Ubuntu 14.04 on the same HDD working well on a dual boot.
I added an SSD, changed BIOS boot order and installed a 'lite' version of Windows 7 on the SSD. I am doing project work and need a version with no antivirus, etc. Now I have changed the BIOS boot order back so I get my grub menu. I want to add an entry to that will allow me to boot the lite drive from grub instead of having to switch the BIOS back and forward every time. I do not want to reinstall Ubuntu or my main Windows 7, but I will consider redoing the 'lite' version if that will help me achieve what I am looking for.
I have a feeling that this should be pretty easy, but I am not seeing it. The obvious solution of running grub-update
is not seeing the Windows 8 installation. In the fdisk
listing below, /sda
is my working dual boot. /sbd
is my SSD (note the error reported), /sd
c is my shared storage drive and /sdd
is my removable backup disk.
