I have found a good thing to do before you install Solaris over linux is delete the linux partitions with something like fdisk. You can just go ahead and install Solaris and it should detect the Windows install and add a boot option to the grub menu for it. So you don't really need step-by-step, dual-boot instructions - but perhaps you need, step-by-step plain old install instructions. So maybe something like this:

Just be careful to not delete your windows partition :) Solaris won't work out of the box with your wireless card - you will need to install the driver manually. What type of card is it?
