[Bug 974779] Re: 12.04 beta 2 update to 3.2.0-22 destroyed grub configuration

[YannUbuntu]

ok thanks (BootInfo displayed a wrong information for sda1, i'll report
it to its dev)

Concerning your boot problem, you have the bug with GRUB1.99-21 (Precise), but not with GRUB1.98-1 (Lucid). That's a regression. So maybe the GRUB devs would be interested in knowing if you have the bug with GRUB1.99-12 (Oneiric).
Please could you backup your documents, then erase sda2 and install Ubuntu 11.10 ( http://releases.ubuntu.com/11.10 ) on sda2 ? During the installation, let GRUB being installed in sda (not sda2 !). After installation, reboot and tell us if you get to a working GRUB menu.

Title:
  12.04 beta 2 update to 3.2.0-22 destroyed grub configuration

Status in “grub2” package in Ubuntu:
  New

Bug description:
  
  Pangolin 12.04 beta 2 updates are mangling grub. After an update that does a update-grub rebooting results in a:

  Purple screen with a few columns of faint black lines at the top.

  Sometimes boot-repair disk works, not recently, it repairs to the same
  purple screen and faint black lines.  Attached is the boot-repair disk
  info.

  So I get my multi-partitions going again by installing Lucid Lynx in a
  spare partition. So far, never fails!

  Attached is a copy of the boot-repair info. It said it worked but I got the same purple screen with a few black lines at the top.
  With nothing running can't do an ubuntu-bug grub.

  Sure would like to know how to save grub & configuration so I could at
  least boot live and restore them.

  Super-Grub2-USB did enable me to get the partition running again,
  booting usb hybrid iso.

  Acer Aspire 5253 notebook AMD Dual-Core Processor E-350, 2 GB memory
  15.6" HD LED LCD.

  Thanks much,

  Jerry
