at first we use usb pendrive to install windows os to HDD .while installing windows os, windows will Assign 100MB for boot files to copy in first partition with fat32 format type..
second partition does not Assign drive letter but takes 16MB for MSR files.
In third partition , windows will install with NTFS format.
I need some screenshots to verify In your HDD boot partition is created or not.
If boot partition is created in HDD as first partition means then you can set boot device as HDD , otherwise you cant set.
