grub menu does not display after upgrade to 11.04

[Joe]

Binary package hint: grub2

I originally upgraded to Ubuntu 11.04 from 10.10. After this upgrade, when I restarted, the grub menu did not display. It turned out that the geuyb menu was active, and I was able to use the up-down arrows to "select" an OS to boot into. I later performed a fresh install of 11.04 on a different partition. Again, the grub menu did not display upon restart. In the file /etc/defauylt/grub, I uncommented the line GRUB_GFXMODE=640x480, executed "update-grub", rebooted, and the grub menu did display this time. This solution appeared to work for others as reported over the internet. I originally thought that the grub menu not displaying was the result of incorrect Nvidia graphic drivers (bug report 775870), but I no longer believe this is the case.
1. lsb_release -rd

2. apt-cache policy grub-pc

3. When I either upgrade or do a fresh install of Ubuntuy 11.04, I expect that the grub menu will display after reboot because I have more than one OS on my PC.
4. When I either upgrade or do a fresh install of Ubuntu 11.04, the grub menu did not display after restart.
