One of the hard drives not showing on my PC

[total21]

I was reinstalling Windows 7 and when I was doing that I formatted two separate partitions on a Disk C. The big one was the regular one that I always format when doing that and the seond one is the reserved space system partition (or some other name similar to that, the one that is 100MB or something like that) and this is now showing in my PC as disk D. So there is Disk C and the Windows is installed on that, Disk D, which should not be there, Disk E, which is a DVD-drive, and what should be showing as Disk D originally is missing. I can see this disk under Computer -> Properties -> Device Manager and I can also see it after clicking on Computer -> Manage -> Storage Management.

The last location seems like the place where I should be fixing thing, but I am not sure. I have very important info on that invisible hard drive and there is no option that this data can be lost (a year and a half of full day / full weeks work would go to waste). Can you tell me what would be the correct way of getting out of this.

I need to:
1) Remove the current Disk D and make sure this is set up as the "reserved system space" or something like that.
2) Make that invisible disk show up as the Disk D on my PC

Thanks.

Welcome to the forum. Can you post a screenshot from diskmanager the reserve parition if in disk manager you right click and choose change drive letter you should be able to remove it so it doesnt show up then change the other drive to d:

I did that yesterday and it worked. Would anybody know if the "reserved disk partition" is ok like that. I mean I formated it and I now made it invisible as it should be anyway. Maybe I should make it visible temporarily and add some files to that or something like that? It was formatted, now I made it invisible as it should be and thats pretty much it. I've never formated it before and it also "worked".

You have now a big mess.
- The 100M isn't a reserved partition. Reserved partition is RAW (not formatted).
- The data drive D: is active but has no OS. That means that you can be booting from D: and then transferred to C:

When installing a OS:
- ALWAYS disconnect ALL other drives.
- Boot from the installation disk, go to Install - Advanced - delete all partitions - Create new - proceed. The installation wizard will create the others needed partitions.
- When finished, connect the other drives.
