Bug Description
Hi,
I had the Windows 7 bootloader configured to dual boot either Windows 7 or Ubuntu 10.04.
The Grub2 bootloader was installed to the Linux (ext4) partition while the Windows bootloader was installed to the MBR and first primary partition.
Everything worked fine for about 5 weeks, i.e. in the Windows bootloader I could select either Windows or Linux. When selecting Linux, it would chain-load grub and boot into Ubuntu.
Now I allowed Update Manager for the first time to update Ubuntu and guess what: it now boots into Ubuntu right away. The boot menu does not appear. Apparently the grub update has overwritten the MBR.
WTF!! (Sorry, but this is really incredible!)

P.S. This were all fresh installations on a newly built machine.
