grub-probe: warning: disk does not exist, so falling back to partition device /dev/sda1

The error messages are misleading. The disk exists, you just don't have access to them. Try running that command with sudo.

    I am attempting to get GRUB to boot Windows, but I ran into a problem. Whenever I try to run grub-probe --target=fs_uuid /mnt/bootmgr, I get this:

    grub-probe: warning: disk does not exist, so falling back to partition device /dev/sda1.
    grub-probe: warning: disk does not exist, so falling back to partition device /dev/sda1.
    grub-probe: warning: disk does not exist, so falling back to partition device /dev/sda1.
    grub-probe: error: disk `hostdisk//dev/sda1' not found.
    

    /dev/sda1 absolutely exists. Why is this happening?
