Subject: Boot windows on external disk : "not a valid root device"
Date: Wed, 02 Jan 2013 00:31:14 +0100 [thread overview]
Message-ID: <50E371C2.7000909@guillemet.org> (raw)
Hi,
I have a new Asus N56VZ laptop and replaced the Windows hard drive by a
SSD with Linux installed. EFI Grub2 successfully launchs Linux.
Now I'd like to boot Windows from the original hard drive mounted by USB.
No matter what I try, either using grub.cfg or command line, Grub's
chainloader fails :
> set root=(usb0,gpt1)
> chainloader ($root)/EFI/Microsoft/Boot/bootmgfw.efi
Error: not a valid root device.
The content of the drive may be seen using "ls".
What's the exact meaning of "not a valid root device" ?
Thanks,
--
Hervé
