Well from what I've seen Microsoft is going to need
a patch to Windows 7 'Disk Management'.
The RTM has problems when creating partitions
for multi-boot systems and another issue when
doing a clean install on a system that has three hard drives.
I can't speak about the multi-boot system issue, since I have no
experience with that. But I can tell you that I have a
three-hard-drive system, and had no problems doing a clean install on
it.
Well I have two hard drives configured as logic
drives (each has only a single partition). The third
drive is new and the one I tried to installed Windows 7
(single boot) and 7 fails to create the 100MB system
partition during the install process. I've tried two new
hard drives and both have the same issue. If I remove
the two other drives the Windows 7 installs without any
problems.
The multi-boot problem is another issue, but it to centers
around 'Disk Management' and the ability to create a logical
drive with the remaining free space on the one and only hard drive.
So the way I see it is Disk Management in Windows 7 has
one or more bugs as XP has no problems with mult-boot or
using any of the remaining free space on a new drive.
