I have been trying for 2 days to get W7 pro to install on RAID5 set up through the motherboard. I have 4 identical 2T hard drives which are no problem to set up as a 6T RAID5 array on the motherboard. The install starts with no problem, I load the RAID drivers and convert the array to GPT format and point the install to the 6T GPT drive which the install sets up with the 3 partitions required but then the install stops and says it can't install because the computer will not boot to the created partition.

Converting the array to GPT format destroys the raid boot record on the disks. Follow the Raid install instructions and it will work.

Okay, so now when I started the install after almost 2 hrs for diskpart to format the drive, I get "Error occured while preparing the system volume. Error code 0x8004242C". Any suggestions?

Hmm, That's "The volume size is too small.": http://msdn.microsoft.com/en-us/library/dd208031.aspx

Bearded Dan I am now experiencing the exact same problem, and with an MSI board. I wonder if possibly the RAID BIOS isn't the culprit. Did you ever find a solution?

What I came up with is that WIN 7 will only control a 2 TB section for it's drive. I set up the RAID array with a 2TB area for the operating system and the balance as a second array and it's been working fine ever since.
