Dual Boot Kubuntu and Vista


I would like to dual boot Vista and Kubuntu on my laptop but the dual boot guides I have seen on the net are not suited to how I want to do my installation mainly because of partitioning so I would like you to help me out. If you could possibly reply with a step by step guide i would be very grateful.The following problems are bugging me.
1.How do you create an extended partition and a logical partition during the installation of Vista.
2.I would like to use the EasyBCD bootloader but I am a bit confused.How do I tell Kubuntu during installation not to overwrite MBR but to install GRUB somewhere else so that I can use the EasyBCD bootloader. I am using the Kubuntu Desktop CD.

1. You can't. You'll need to use another partition editor. Best is Acronis, free ones include Paragon and GParted.
2. During Kubuntu setup, you'll see a button called "advanced" When you click it, you get a dialog asking you to install GRUB to hd0. Change that to reflect the Ubuntu PARTITION instead of drive, so that becomes something like hd0,2
