The hard drive has two partitions. I'm installing Windows 7 on the second one. It automatically gets assigned the drive letter C (and the first partition becomes D). Is there any way to override this assignment during installation? It's a dual-boot system, and I want drive letters to be consistent. On the vanilla drive selection dialog, there's no letter assignment UI.

You may not be able to change it in setup but after installing you may be able to change it by going to Control Panel > Administrative Tools > Computer Management > Disk management and right clicking on the drives. There's an option to change the drive letter there, however i'm not sure if that will screw anything up. Try it and find out? Good luck!

Does not work for neither system partition nor boot partition. – Seva Alekseyev Apr 9 '10 at 3:08

There is a workaround for this. You can install Windows 7 first, on the first partition, then install the other OS on the second partition, then restore the bootloader.

Another way would be to change the letters 'offline'. I.e.: use a bootdisk to write the preference of drive letters to the hard disk. There should be software capable of doing this.

Um, won't the partitions get reversed in the second installation then? :) – Seva Alekseyev Apr 10 '10 at 1:02
Well, maybe. Depends on the other OS :). For some reason Vista and Windows 7 call the partition on which they are installed C: by default. XP, if I'm not too much mistaken, just starts at the beginning of the disk. So if your first partition contains Windows 7 and the second XP, both will refer to the first as C: and the second as D:. As far as I know, at least. – Zsub Apr 11 '10 at 15:54
