[Bug 999948] Re: Ubuntu fails to account for separate boot partition

[Phillip Susi]

There is no such thing as error 15 in grub2, so either grub2 did not get
installed, or was installed to one drive and the machine is still
booting from a drive with grub legacy on it.  Do you have more than one
drive?  Where did you choose to install grub2?

Title:
  Ubuntu fails to account for separate boot partition

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  In Installing Ubuntu 12.04 Desktop, my system has a separate boot
  partition /boot on the same drive.   When installing Ubuntu 12.04,
  Grub2 does not seem to account for that and when the installation is
  finished and you reboot looking to get into Ubuntu 12.04 desktop,
  grub2 generates an error 15 and halts.

  What I have tried:

  (I have tried this on two separate machines so I know it is machine
  independent)

  Please note:

  (Grub1 was installed previously on these machines but another machine
  had grub1 AND no /boot partition and it worked so I Know it has
  nothing to do with Grub1)

  (As stated already, both machines had a separate /boot partition so I
  can reproduce the error)

  (as stated:)

  I tried the install on a third machine with just a / partition and it
  worked perfectly so I know having grub1 already installed does not
  affect this situation.
