You are correct that, in a multiboot system, windows needs that first 
partition to be FAT and in the first part of the drive. But with only one 
OS installed I'm not even sure why PM warns you. Presumably you partitioned 
this drive so you could image the C: drive so you can't lose much if 
disaster strikes (wouldn't be any other good reason to partition).

P.S. Having that page file on a different partition doesn't help 
performance. It has to be on a different physical disk. Even then you have 
to have too little RAM for it to be particularly noticeable.
