Windows 7 - Drive Lettering

Recommended Posts

Hi,

I wonder if someone can please help.

I dual boot XP & Win 7.

The HDD lettering in Win 7 (In My Computer) is as follows.

Is there any way to change the partition / drive lettering?

Basically, I wanted to have XP as C:\ and Win 7 as D:\ [the drive lettering on DATA (E:\)] is fine.

Here is a pic taken from the net where the Win 7 boot / active partition is not labelled as C:\ but as E:\.

Also, can someone please tell me if that is possible in XP.

This is my current layout.

I wanted to have  the following: XP on C:\ is fine. But I wanted to have Win7 as D:\ and DATA on E:\

Can this also be done please?

Many thanks for any info provided

Cheers

Disk Management.

Also, why not move XP and Vista to run on VMs instead?

That's very unlikely.

Windows 7 ist almost "hardwired" to C:\ and from within Windows (i.e. while Windows is running) you can't change it anyway.

Even if you do manage to change its drive letter somehow you would run into a lot of problems because all the registry settings would still point to the c:\ drive and a lot of your applications would no longer work correctly.

So don't do it and don't even think about it...;)

Yeah. I tried and it said no.

Ok. Best leave it alone.

In XP, I did manage to change the drive letter of Win 7 from E:\ to Z:\. However this is on a test system. 

I was just trying to tidy it up so as to look more orderly, but perhaps better not to touch anything and change any associations.

Cheers and thanks

Yes, it's always possible to change another partition's drive letter but you can never change the drive letter of the partition you booted from, neither on XP nor on Windows 7.

Actually you can (not while you are booted to it, of course, but you can actually change it while offline in such a way that at next boot it will have a different drive letter), but it equates to opening a large can of extremely lively worms.

Though it can be done, it is far from being easy, let alone failproof, involving, besides editing (offline) the DosDevices keys in the Registry of the affected installed system, replacing thousands of hardcoded references in the Registry and heaven only knows how many hardcoded paths in .lnks, settings files and what not.

Thanks jaclaz, I am now completely and totally convinced to leave the drive lettering as is.

Cheers
