What was once coral, then redmond, and now most recently Lycoris linux doesnt build partitions right. If you have one HD and install lycoris linux on it along side windows, it screws up the partition table.
I have had a few flavors of linux and removed the partitions without a hitch, but this flavor (lycoris) partitions cant be removed by partition magic or any other partition editor without wiping the entire partition table because of "crossed over" partitioning that lycoris does.
I tried PM 7.02, it said it repaired it, but then would error out and close itself. I tried partition manager, and it errored out. Heck for shits and giggles, I even tried FDISK, and it laughed at me...LOL
I just backed everything up, and wiped out my entire partition table using AEFDISK.
All will work fine with both installed and as long as the linux partitions are intact. The problems comes when you want to remove linux from your machine.
Now your probably thinking why did I delete it so fast? Well lycoris is a very bare bones linux OS, and I couldnt get online with it because it didnt come with PPPOE so i could connect to my dsl. I really didnt feel like screwing with it, so i wanted to rid it.
This isnt to downgrade this OS in anyways, just a fair warning for the folks that may not want to start completely over if they dont like linux.
