windows - Dual boot and disk encryption

I need to dual boot these:

• Unencrypted Windows 7 partition


• Encrypted Linux partition (/ and /home)

I was thinking to erase the entire disk then:
Install Windows 7 then install a linux distribution in this way:

• /dev/sda1 windows boot - unencrypted


• /dev/sda2 windows system - unencrypted


• /dev/sda3 /boot - unencrypted


• /dev/sda4 LVM encrypted


• /dev/sda5 swap

Do you think that it will work? is it safe?

Thanks a lot!
