It seems to be the same. But why on earth did you want to do this.

It will most certainly ruin Win7 beyond repair.

What exactly is it you want to achieve?

I have several times installed xp on the same pc.
My idea is do the same now with the w7 system.
Under xp I haven't had any problem changing the letter of the system, or the letter of the boot.

Because I'm a lost puppy in the pound. Contro let me know if I understand you correctly. You want to install Windows 7 several times on the same computer at the same time. You are desiring different drive letters for each install. Is this correct?

One important caveat, W7 is not XP.
Any drive w7 is installed on will become the C;\ drive.

I am trying to remember what I did.

This is my plan with the help of everyone.

I have seven hard drives on my pc under windows xp pro.
One of these drives have partitions. In some of those partitions I have installed six times windows xp pro.



At the present moment I think I have made my first mistake according to your considerations.

I have installed w7.64 over STo (that's the letter I: in the old structure).

What can I do ? I think the best option is substitute the present systems disk. The present one is 1 TB. One of 1.50 TB possible would be fine. Or even 2 TB.

Make provisional partitions in the new disk and make certain the first installation goes to the C: partition in the new disk where the bcdedit.exe must be.
That will be my first system under windows 7 with the new boot. I have security copy of all about the c:\ at this moment.

This are by custom my installation letters : C: , D: , F: , I: , M: , N:

mmmm

What I did ?

I have a dvd unit

I will connect to the mother board the system disk when install over C: . And the dvd.

Then install a second system on D:

Then connect the second hard drive. Select one with only one partition.

That occupies the letter E:

I will install then over the partition F:

Then connect the third hard drive to get the installation letter I:

Install in the system disk the fourth system.

(I suppose I can even restore an acronis security copy from the old pc hard drive with my retail version of xp)(but this is not necessary)(So I would install w7.64bits in the fourth system)

Then connect a new hard drive to get the letter M:

And installs over the letter M: . There goes my main system.

And then installs over the letter N: in a new partition in the system disk.

Ufff.

I think this was I did with windows xp pro.

But I remember was not so simple. By any reason a system may be seen from other with a different letter I have to change.

And that is the case the kb223188 because initially was C: and in other system is another letter.

But this is not my present situation. Because I made the mistake to install over I: the new windows 7. And now is really C:

Possibly I can restore image copies and have security copies of the boot.ini.

But this is irrelevant with the plan to change the system disk to another more confortable.

Can I do this with windows 7 64 bits professional edition ?

Note : So many systems are the result of my little trauma with xp. At the present moment I have over 60 virtual machines under virtualbox. Possibly so many systems perfectly installed is not necessary, but i am very used to call M: my main system and I am not a programmer but have many scripts pointing to that letter.

Owwwww. Hurts.


What happens if I install twice or three w7 on the same pc then ?

I use a CRM that many links point to the letter M: where my main system is.
