System Preferences - Start up disk can't see Windows

[Justelis]

Hello,
recently I reinstalled Windows 7 from Ultimates to Professionals I used USB to do it.
So I spotted that my Start up disk can't see Windows 7.
What I can see when I go to Start up disk



And this is how my Disk Utility looks like:




So my question is how I can make Windows visible on Start up disk?

P.S I can boot into Windows via holding down the OPTION key.
But when I boot Mac OS I cannot go back to Windows automatically, I have to press OPTION key then select Windows.

Thanks

Did you load the drivers?

 

[Justelis]

Yes I did.

 

[Kaveman]

Was it the full retail version or an OEM version of Windows?

 

[Justelis]

What do you mean by saying OEM?

 

[Kaveman]

A copy that came with another computer.

 

[Kaveman]

why did you format it MS-DOS (FAT) not NTFS

 

[Justelis]

I was using USB for the first time to install windows that's why
So only way to make visible is to reinstall windows?

 

[Kaveman]

So you didn't "Install a Retail Version from the supplied DVDs" like it said?

 

[Justelis]

No I didn't. Maybe you know solution?

 

[Kaveman]

Solution =

"Install a Retail Version from the supplied DVDs"

And there is no other solution without reinstalling windows?
