I've installed to hard drive using 50% of HD. So Windows has 2 partitions.

Then I manually made 2 partitions for ubuntu:

#3 primary /boot ext4
#5 crypted section with volumegroup for root and swap

Then the installation asks me that where to install grub and I write:

/dev/sda3

And the installation says fatal error. Where do I go wrong? The reason is that I want to create whole drive encrypted HD with Windows 7 and Ubuntu 12.04.

You can't install grub on /dev/sda3. Try installing it on /dev/sda. – jokerdino Oct 12 '12 at 13:15
    
normally it's perfectly possible to install grub into a partition instead of the mbr, but I don't know if the partition may need a boot-flag. – FSMaxB Oct 12 '12 at 17:50
