I was looking to use /usr/sbin/grub-install from the Cygwin GRUB2 port
to install to a partition. I can't seem to determine however what to
use as the install_device argument. There aren't any device nodes w/
cygwin, and grub-probe insists that it has error finding a device for
/boot/grub (since /dev isn't mounted).
The INSTALL_DEVICE argument should be the Cygwin device name of the boot
disk (not the boot partition), typically "/dev/sda". This device node is
provided by Cygwin even if it does not appear in /dev directory.
The grub-probe tool can be used to detect the device name of a specific
partition:
# /usr/sbin/grub-probe -t device /cygdrive/c
/dev/sda2
Here some recommended steps to install grub2 on a new machine:
- Create a grub rescue image which includes osdetect.lua script:
$ grub-mkrescue --output=rescue.iso /usr/share/grub/osdetect.lua
- Burn rescue.iso to a CD (or 'dd' it to floppy or USB stick).
- Boot the rescue disk.
- Detect installed operating systems and run created boot menu:
grub> lua /osdetect.lua
grub> normal
- Boot Windows through boot menu.
If the above works GRUB is compatible with the machine and you have a
working rescue disk in case grub-install fails.
- Install grub:
# /usr/sbin/grub-install --no-floppy /dev/sda
- Create grub config file:
# /usr/sbin/grub-mkconfig /boot/grub/grub.cfg
