What procedure should I follow to set a dual boot (both Win-7 x64) on a machine where (ideally):

  • Both operating systems will be installed on the same physical disk in different partitions
  • When booting into either operating system the contents of the other OS partition disk will not be seen (this just seems safer)
  • Other hard drives in the system will be visible by both OS's

1 copy of Win7 is already installed.

Is it as simple as shrinking the existing volume and creating the partition, then sticking the CD in and booting off it and formatting the new partition and then installing another copy of windows onto the new partition? Or will that not work? Or are there gotchas?

You just stick the CD in and install it on a separate partition to your first, it will automatically add the second operating system to the boot loader to. Although they might both have the same name at first (you can change the bootloader names from inside Windows)

Thanks. Just to note thoguh, by default you can see the other c:\ drive, it just appears as any other drive. – Sam Holder May 18 '12 at 8:50
I'll remove that part from the answer, maybe that was an old XP thing. – Amicable May 18 '12 at 10:51
@SamHolder - This is to be expected. If you want to protect the data on each partition encrypt them. – Ramhound May 18 '12 at 12:32
@Ramhound I don't want to protect the data, just to avoid casual mistakes. Removing the drive letter for the other machines c:\ drive is the way forward I think – Sam Holder May 18 '12 at 12:44
