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

It will most certainly ruin Windows 7 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 Windows 7 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, Windows 7 is not XP.
Any drive Windows 7 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 Windows 7.64 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 Windows 7.64bits 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 Windows 7 on the same pc then ?

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