[Bug 475881] Re: Selecting Grub2 menu item for Windows 7 reboots PC

[Jean.c.h]

@Konrad Materka, 
Bug #486499 is a duplicate of Bug #402154. I've tried marking it as such, but won't work for some reason.
This Bug (#475881) and #454930 are likely related to #402154 also.

Title:
  Selecting Grub2 menu item for Windows 7 reboots PC

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  After installing Ubuntu 9.10 I am unable to use the GRUB2 menu to boot
  into Windows. When I select Windows from the GRUB menu the PC simply
  reboots.

  This happens using both desktop and alternate installs of 32bit and 64
  bit Ubuntu 9.10. I am also unable to load GRUB to a floppy or USB
  stick as the installer fails to recognise the media, producing a
  'fatal error' message - I then either have to choose to install to hd0
  so I can't boot Windows or not to install so I can't boot Ubuntu.

  I have also tried various install combinations, the latest of which means i have removed my 2nd disk and I'm installing Ubuntu to a partition on the same drive as the Windows partition. There are no other hard drives connected to the system, but the same problem remains:
  * Windows 7 RC Build 7100 64bit is on SDA1
  * Linux Boot is on SDA5
  * Linux SWAP is on SDA6
  * Linux Ubuntu 9.10 is on SDA7

  During all alternate installs I have selected /dev/sda as the location
  for installation of GRUB. During all desktop installs I have confirmed
  the installation path for GRUB is hd0. The GRUB menu correctly
  identifies in every install that the Windows loader is a Windows 7
  loader on /dev/sda1.

  I have also posted a query to the Ubuntu forums but I'm not having
  much luck - lots of responses, but either they haven't read the post
  and the problem or I get advised that their similar setup works fine
  and I should search the forums for a response. NOT very helpful :(

  My ultimate aim is to be able to select my OS using Grub2 (i like the
  idea of being able to use background images), although I will settle
  for another solution that works, for example having to use a floppy
  disk to boot - I do not want to have to use EasyBCD.

  Thanks
