I'm trying to install Windows 7 64-bit on a pc with two 596 GB SATA hard drives in a RAID 1 array, using a Rosewill RAID controller.
The Rosewill driver CD did not have 64-bit drivers on it, so with the help of Rosewill tech support, I downloaded 64-bit drivers from the chipset company. When I boot from the Windows 7 CD, choosing advanced install, it doesn't detect any drives, and so I click the "load drivers" button, insert the driver CD, and it finds "Silicon Image SiI 3132 Softraid Controller". But then when it loads the driver and I am back on the Windows 7 setup screen asking which partition I want to install Windows 7 to, it has a message "Windows is unable to install to the selected location. Error 0x80300001".
It shows that I have one disk, listed as 'disk0', but two partions:
- Partition 1: System Reserved 100 MB
- Partition 2: 596.1 GB
I am trying to select Partition 2 as the location for Windows.
I've tested the drives and they are fine. I can unhook the RAID controller and install Windows on a single drive just fine.
Any ideas what the problem is?
