Comment 101 for bug 568050

Phillip,
sorry, I need a bit more help. Using your ppa:

After waiting for the keyserver to finally connect, I am trying to reinstall the system as a single boot Ubuntu 10.04 with raid mirroring.
I got to this screen

──────────────────────────┤ Configuring grub-pc ├──────────────────────────┐
 │ │
 │ The grub-pc package is being upgraded. This menu allows you to select │
 │ which devices you'd like grub-install to be automatically run for, if │
 │ any.

...

And I said OK.

Then I get here:

────────────────────────────┤ Configuring grub-pc ├────────────────────────────┐
 GRUB install devices: │
                                                                               │
    [ ] /dev/sda (750156 MB, ST3750528AS) │
    [ ] /dev/sdb (750156 MB, ST3750528AS) │
    [*] /dev/mapper/isw_bifgdfbbc_Volume0 (750153 MB, isw_bifgdfbbc_Volume0) │
                                                                               │
                                                                               │
                                    <Ok>

Again, I select OK. I just want the /dev/mapper one, I think, because the other two are the raw disk drives for the raid.

I then get:

┌──────────────────────────┤ Configuring grub-pc ├──────────────────────────┐
 │ │
 │ GRUB failed to install to the following devices: │
 │ │
 │ /dev/mapper/isw_bifgdfbbc_Volume0 │
 │ │
 │ Do you want to continue anyway? If you do, your computer may not start │
 │ up properly. │
 │ │
 │ GRUB installation failed. Continue?

What do I do?

Thanks,
Herb
