Change letter of the boot drive or the system drive

Off Topic. Some years ago I made an authentic disaster but works.
Obviously I always try to work less. That's the point. Manage several systems is not my favourite thing. I do because I am traumatised with windows. Ejem.

What I did was :

Literally copy one partition files to another. Of a system !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Then enter in the windows registry and modify every key pointing to the initial unit to the new unit where all the files were copied.

And works !!!!!!!!!!!!!!!!!!!!!!!!

I remember some minor problems perhaps of hive keys or special misconfigurations that almost solves reinstalling that particular program.

Windows is a flexible environment.

I have six systems :
System Ocium

SAT (excuse me) is the equivalent to Technical Assistance Support

I am from Canary Islandsssss !!!!!!!!!

You only really need one OS to do all of that. You would just have to have your work, other for ocium, etc on separate partitions and disks to access them from w7. If you have w7 Ultimate or Enterprise, you can install XP mode which is a XP OS in a VM.

The TAS (Technical Advice Service) tells me that professional version have that ability too.
But I am used to use VirtualBox.

I have seven disks at the present moment. And one of them is for systems.
Of course I use data disks.
But I spent all the weekend looking for software in softonic......
It's my trauma and my vicious....

LOL! Maybe it's time to learn to clone a drive or partition.

Yesssssssss.
I do with virtual machines. Ufffff . A little of peace.

Acronis can restore in hardware different, but I haven't try over a different letter.
Of course I can try, but I think is not a good solution. I remember when I try renaming the letter pointing to in the windows registry. It's a very very suffering work.

Perhaps I don't know enough this subject.
Of course I was thinking about clone windows 7.
But is it possible ?

I suppose i can clone partitions inside the same pc.

And clone partitions in the virtual machines of course.

What is the best way ?

I have an Acronis copy of the recently installed windows 7.

What will happen if I restore a copy over a different letter ?
If Windows 7 is indifferent to any other letter different from C: nothing may happen. No ?¿?¿?¿

me too no. I have no memory but I have tutorials. I use the live ubuntu cd for partitioning

I am not sure of this post
windows 7 - Reassigning drive letter for cloned system partition - Super User

because I have seen other post telling that the tric kb 233188 give problems with the license of windows 7

I prefer to wait a little more to listen more opinions.

Are you aware you must boot the Win7 installer for it to correctly install to C? If you run it from XP then C will be locked and unavailable.

Boot the installer now, follow these steps to Clean Install Windows 7. At the drive selection screen, choose the Win7 target partition, delete, recreate and format it, then click Next to begin install.

Win7 will be C when you are booted into it, XP will be C when you are booted into it. This is correct. Running Win7 installer from XP is not correct.
