Is it possible to install windows on something other than C:\?

Hello,

I was wondering if it was possible to install windows on another partition than c:\
So for example, my windows folder will be W:\windows or something...

Thanks.

Yes, I know you can select different partitions, but that will just make that selected partition c:\windows\, and not %driveLetterOfMyChoice%\windows...

I guess not, have a look at the note on this tutorial,

That says you don't want to change it so there must be a good reason for it.

You can try installing from an OS to a partition you have already created with letter.

Hello Necrowizard.



I'm not sure this will work for what you want as I haven't tried it myself.

As you must have a Windows 7 full installer, have a look at Methods One of this tutorial at the link below to see how to boot to diskpart so you can set a partition letter before the install starts.

Though it may cause serious issues when you install parogram/apps and they look for C: to install to; be sure to post back with any further questions you may have and to keep us informed.

Though I didn't think it would work, I wanted to have a go for my own experience so here are the results; it did not work.

In diskpart I did a clean all just to have a fresh start, then I created the partition.

Then during the install, I did not do a format here.

Here's the end result.

Yes, it's possible.

It requires running a complicated script from winpe.

Unless you are able to do that, you are stuck with 7 selecting the first available letter ( That will be C if you install from boot as A and B are reserved for floppies)

Thanks SIW, is there a link to this info I could study?

I've seen this as a result of a custom upgrade install - As the install is run from the C: drive when windows looks for the 1st available drive A;, B;are unsuitable and c: is actually in use. As a result windows will be installed to the next available drive - maybe D: but often higher as the DVD drive is an unsuitable drive and is normally d:.

Not a common event but possible - RTM Windows 7 may make this impossible by rebooting before drive allocation but not sure
