If you would like to install Windows on the mSATA SSD, you must first change it to a basic disk otherwise you won't even see it in the list of partitions while the Windows setup intitializes.
To do this:
1- Go to Control Panel, Administrative Tools, Disk Management
2- Find the mSATA 64 GB SSD, you would know which one it is from the size, it would be around 59.63 GB
3- Right click on the part where it says Disk 0, then choose convert to basic disk, if that option wasn't available, choose convert to Dynamic Disk, then try right clicking again until you see convert to basic disk
4- Once it is a basic disk, you would see it in the partitions list when you are trying to install Windows!
