[Bug 908109] [NEW] Oneiric 64-bit installer Grub no HDD boot Lenovo B570

[Launchpad Bug Tracker]

As per the forums, this is a 64-bit laptop, and the 64-bit Live CD "Try
Ubunut" mode works perfectly on it, but when installed to disk the Grub
boot loader doesn't work.

I selected the option to resize the Windows partition and install Linux,
and it did everything perfectly, but would not boot Linux afterwards.
The system came up into the Windows 7 black "start in safe mode" option
screen. If the Active Partition flag for the Windows boot partition
(/dev/sda1) is turned off, then the system will not boot from hard drive
at all, and falls through to the next boot option in the BIOS, which by
default is PXE.

Also as per the forums, the 32-bit Oneiric installer works fine ... I
bought the laptop for my 74-year old father for Xmas and he is unlikely
to care about using all 4GB of RAM, or running 64-bit VMWare setups, so
I just did the workaround of using the 32-bit installer to reformat the
Linux / partition (/dev/sda6) and install 32-bit Ubuntu.

I have included a copy of the partition table, boot block and /boot/grub
as laid down by the 64-bit installer.
