Windows 7: 7even System partition letter change.

Just to confirm what Barman58 said, if you install 7 from within an existing o/s - using a virtual drive , it will take the next available letter and not assign itself C.

What i am confused about, it that there is no way to just choose the destination partition letter before installing the OS. i clearly remember my last job, where about fifty computers (WinXP i think... maybe 2k) had their whole OS, and all program files on disk D. i hardly believe that admins made all the things you just listed it really looked more like a *very* custom installation. Isn't it possible?
Yes, it is possible in a large scale environment, they just performed the above tasks once (for each PC MFG type), took an Image, and imaged all the PC's. You should have one Programs file folder per OS-installed partition. Going against this grain would be, as said, difficult to maintain for an extended period of time.

once again, if you want:
when i login to vista, i see: drive1{C;D}, drive2{E}, system vista partition is C, and that is RIGHT.
when i login to seven, i see: drive1{E;D}, drive2{C}, system seven partition is C, and that SUCKS.

what i want to see is:
i login to seven, i see drive1{C;D}, drive2{E}, system seven partition is E.
If you will change the HD so as Win7 (intsall to E:) is not on the same HD as Vista.
Vista will remain C:\ and Win7 will remain E:\

As you can see; C:\ is Vista and will remain that way untill I DELETE Vista.
L:\ will remain Win 7 untill I change that by removing Vista, then change my Boot drive to L:\ where it then will be master Boot drive, which will then become C:\ unless I want it to remain L:\ My mobo is a ASRock where I have the option using F10 to change my DEVICEs sequence to fit
how I boot.

N:\ Printer, Scanner MFC M:\ is empty card reader. Version is Win7 Ultimate 7137 which has been removed from lower right hand corner.

You may have answered this, but when you go to:

'Computer Management' -> storage -> Disk Management -> Right click (C: ) -> Change Drive letter and paths -> Change -> D:

Does this work for what you need?

You really should go ahead and reinstall the programs through seven and not try to reuse them from the vista install.

Drive lettering is relative to the OS installed.

vista ultimate

And what a nice orgy it could have been...

ok then, ill try to move everything to win7. btw, are you sure i won't have to re-install it after release?

oh, and a new idea! just wondering...
it it possible to make a virtual drive, hard-linked to another one? for example, drive X, mapped to disk1partition1, so that if i click on it, i see disc C, but named X? basically, its like assigning two letters to one drive - one actual (unchangeable), one dynamical. And if that possible, we can come to the next situation (let's forget the already existing software for now):

when i login to vista, i see: drive1{C and X;D}, drive2{E}, system vista partition is C, all the software were installed with the X letter.
when i login to seven, i see: drive1{X;D}, drive2{C and E}, system seven partition is C

and a thing about software options - we can also map the %userprofile% win7 link to the disk X, no?

i know i'm crazy, thank you

Not sure what exactly you want to do with his (or even if this still works in Windows 7 ), but Windows has always had the "Subst" command which allows you to assign a drive letter to a folder either try Subst /? in a command prompt or have a look here ...

The command is present in 7 but I think it may only work in a command prompt
