My Dell system came with Win7. I installed Ubuntu 10.04 into an LVM encrypted partition with the /boot unecrypted on it's own partition. The PC boots directly to the Ubuntu decrypt screen with no option for choosing a new kernel or the Windows partition. I've attempted update-grub, but the GRUB menu is never presented and the Win7 installation is never detected. I'm guessing I installed GRUB incorrectly...any ideas on what and how I can correct? Thanks!
Recent versions of GRUB have the timeout hidden. You can hold down left-shift during boot to bring the message up or edit your /boot/grub/grub.conf and remove
For grub2 edit the /etc/default/grub file and make the following changes:
NOTE: The # symbol will comment out the GRUB_HIDDEN_TIMEOUT and will enable the menu
After making the changes run sudo update-grub to apply the changes
