Windows 7: Need help with dual boot, hiding a partition

Need help with dual boot, hiding a partition


I've just installed Windows 7 64-bit on my desktop PC as it worked so well for the past month on my laptop I shrunk my Vista 64 partition and installed Win 7 x64 build 7000 on the new partition. All went smooth and well!

As I wanted to transfer some files and settings from my Vista install to my new Win7 I assigned a drive letter to my hidden Vista drive in the "Disk Management" utility and went on with my business. Now, as I'm done I'd like to hide my Vista partition again but I can't get it to work

When I select my Vista partition and select the "Change Drive Letter and Paths" and then press the "Remove" button I get the following error box:

"Windows cannot remove the drive letter of your volume. This may happen if your volume is a system or boot volume, or has page files."

My Vista volume is the first volume of the physical drive, the boot files is there but I don't have any page file on it. How come this drive could be hidden and revealed in the first place but not hidden again?

All and any advice is most welcomed!

You may need to use a 3rd party app.

I haven't tried to do exactly what you're after, but a lot of use Paragon Partition Manager 9, it works really well on Win 7 x64.

Paragon Partition Manager – resize partitions, partitioning software

Easeus partition manager also works ( Pro version or higher - the home version only works on x86 ).

Norton Partition Magic alternative - EASEUS Partition Manager Professional Edition

Acronis Disk Director does not:

Hope it helps

Thank you for your answer :) i thought it would be possible using windows 7 alone as it's possible to make a volume unhidden... guess I was wrong then
