Win 8 can't see partition

.I set up a new partition for a win 8 install. Win 7 can see it but not the Win 8 install. Can anyone help.?

Thanks
Lawrence

Sorry, I must have screwed up. I thought I had created a separate partition for Win 8, but Disk Management shows what I have done as Disk 2 Removable with No Media. I need to get rid of this and start again. I believe there is a tutorial addressing where Win 8 install will create the partition as part of the installation. Can anyone point me in the right direction

Regards
