    Is there a way i can include windows on the GRUB menu? I tried just creating a link called Windows that pointed to the windows drive but that didnt do anything.

    Then i tried acronis os-selector boot manager but it could only find the linux drive.

    I just recently installed linux to a seperate hard drive. If i disconnect the linux drive, window's can be detected and repaired using the windows cd but not sure how to get a proper dual boot where i can choose up and running. Its one or the other at the moment.

    Advise please?

    Edit the menu.lst file, in /boot/grub, and add:

    title Windows
    root (hdx,x)
    makeactive
    chainloader +1

    where (hdX, X) is your C:\ drive, numbers start from zero

    If Windows is not on the primary hard drive you'll need to add an additional line to the Windows boot section:

    map (hdx) (hd0)

    Where hdx is the drive with Windows on it.

    Also if the Windows partition is NTFS formatted I think you'll have to use 'rootnoverify' as GRUB can't read/mount it:

    rootnoverify (hdx,x)

    It shouldn't be. GRUB uses it's own device identifiers (hd0), (hd1),...,(hdN) and maps these to the drives in your system regardless of them being hdX or sdX.

    Bear in mind that my suggestion above assumes that you have Windows on (hd1) and not (hd0). If Windows is on (hd0) then the 'map' lines aren't required.
