Windows 7: Windows 7 Ultimate not recognized

WIN 7 Ultimate x32 and x64
Windows 7 Ultimate not recognized

Hello !

I've just installed Windows 7 Ultimate x32 on my C: HDD. My D: HDD was completely free so I installed Win x64 7 Ultimate ... Well, everything went smooth ... But my problem is:

If I am in Win 7 x32, the x32 installation is displayed on disk C:... and the x64 installation is displayed on disk D:
If I am in Win 7 x64, the x64 installation is also displayed on disk C: ... and the x32 installation is displayed on disk D:
So there is no unique HDD.. ID?!

Now I tried to rename my C: HHD driveletter to D: , so the letternames would no longer bother me ... But it didn't work ...
So I went to Control Panel / Administrative Tools / Computer Management / Storage / Disk Management, nad clicked right on "Other actions / view / drive paths... but neither of the two installations is recognized ...

Well, the story goes on ... I inserted my WIN 7 installtion DVD and went to the repair options ( you know this black console /fixmbr...), and tried to repair the MBR... But what I saw was that the x32 version is installed on my D: HDD, while the x64 installation is apparently installed on a E: HDD ... Somthing's wrong here ?!?

Now my question is: Could you tell me why my windows is not working properly? I would like my computer to recognize the installation and get proper letternames for my installations... I hope you can help me and thank you in advance

This is completely normal and won't affect peformance at all unless you have messed up your system by trying to change OS drive letters which never works.

The OS you are in will always see itself as C: with Windows 7. The only way to avoid this is to install from the other OS so the drive letter is occupied during install, but you cannot do that when one is 32 bit and another is 64 bit.

WIN 7 Ultimate x32 and x64

Thanks !

But why is it recognized as E: HDD ? Or in other words, why is not recognized at all... (in my Disk Management as a Windows installation?)

btw.Is it possible to install x32 from the x64. Would I avoid this problem?
