3 OS-specific notes about grub tools

On OS which have device nodes similar to Unix-like OS GRUB tools use the OS name. E.g. for GNU/Linux:

# grub-install /dev/sda

On AROS we use another syntax. For volumes:

//:<volume name>

E.g.

//:DH0

For disks we use syntax:

//:<driver name>/unit/flags

E.g.

# grub-install //:ata.device/0/0

On Windows we use UNC path. For volumes it’s typically

\\?\Volume{<GUID>}
\\?\<drive letter>:

E.g.

\\?\Volume{17f34d50-cf64-4b02-800e-51d79c3aa2ff}
\\?\C:

For disks it’s

\\?\PhysicalDrive<number>

E.g.

# grub-install \\?\PhysicalDrive0

Beware that you may need to further escape the backslashes depending on your shell.

When compiled with cygwin support then cygwin drive names are automatically when needed. E.g.

# grub-install /dev/sda
