So you mean the OS prober right.

Not during boot, but during update-grub.

Because, during boot you can use 'ls' command to list partitions.

That implies that you are talking about the EFI partition; the ordinary 
Windows system partition (on a BIOS install) --- (they call the boot 
partition the system partition) would just be NTFS.

I have no knowledge about UEFI, but apparently you are trying to boot an 
UEFI installed Windows.
