    Ubuntu 9.10 GRUB Error 11: Unrecognized device string

    (I'm a bit of a noob).

    I performed an update last night on Ubuntu 9.10 64 bit (I started in Ubuntu 9.04, updated in about November to 9.10). Everything seemed to go well with the update last night.

    Tonight I wanted to boot into Windows Vista. I got the following message when I chose the option for other OSes: "Error 11: Unrecognized device string".

    I noticed that it doesn't give the option for Vista. From some other forums I looked at my menu.lst file, which I reproduce here. The last two options (Windows vista and XP) doesn't appear in my GRUB menu at start up. I also include /boot/grub/device.map and fdisk -l below.



    Code:
    ## timeout sec
    # Set a timeout, in SEC seconds, before automatically booting the default entry
    # (normally the first entry defined).
    timeout		10
    
    # .........................
    # A bunch more comments (starting with #) that I removed.  Let me know if I should repost with them.
    # .........................
    
    
    
    ## ## End Default Options ##

    Re: Ubuntu 9.10 GRUB Error 11: Unrecognized device string

    why don't you upgrade to grub2?
    Code:
    sudo apt-get install grub-pc grub-common

    How do I see which disk / sector grub is installed to? Will it be (hd0,0)?

    which version of grub are you talking about? in grub legacy (hd0,0) would be sda1, but in grub2 (hd0,0) doesn't exist (partition numbering starts at 1, hd0 is the mbr of sda).

    Let me just see if running_rabbit07's post solves my problem then I'll try the grub2 approach.

    grub2 is more advanced. it has an os-prober which can add newly installed or missing operating systems.

    I'm still using grub legacy. I'm wondering how will I see where grub is currently installed to. Is there a possibility that it is installed to (hd1,0)? (If it helps in answering, grub is the first boot menu I see.)

    you could download and run meierfra's script, the first thing listed should be which version(s) of grub is (are) installed in which mbr.

    I tried the steps in the link you posted but I get the following:

    root (hd0,0)

    I can access that disk so I don't understand why it can't mount it.
