extended dos / logical partition can't be used for a zfs (and as such, for OS installation), only of the primary partitions. So, without repartitioning the drive (or getting a new one) you're out of luck. > how can I not lose any data but also have my windows There's a wonderful rule of thumb which has helped me a lot: never ever do anything that can screw up a system without a backup. You REALLY need a plan what to do when that partitioning will go wrong -- crossing the fingers and hoping for success will help only so many times. Even just another hard drive, where the important documents and photos are ocassionally copied (now would be a good time) would help immensely. To answer your question what to do: backup the data, remove the extended partition, and repartition the free space to have primary partitions now, instead of logical ones. Cheers, Einar Lielmanis
