Not sure what I've done wrong. Built one PC before successfully in a similar way but this one seems to be struggling.
I have the following components:
No matter how many times I destroy the raid array, format the disks, etc. the boot entries keep piling up. Any idea where I'm going wrong?
The answer was quite involved, so I turned it into an item that hopefully others will get some lasting use from.
This guide will take you through the process of installing Windows 7 x64 on a new machine using the following:
(This assumes you have your PC entirely together, hardware wise, which is outside of the scope of this article)
At this point, your RAID1 array should show as one large drive of 2.7 TB.
When Windows first boots, it won't recognize the drive as a full 3 TB drive -- 760 GB will be left unallocated.
You now have a 3TB RAID1 array fully recognized in Windows 7 64-bit.
I can explain why windows sees two disks, both 746 GB.
If you partition a drive using ancient MBR then you are limited to 2.19TiB.
3TB (probably lsomewhat less since marketing tends to round up) - 2.19TiB (due to wrap around) is about 750GB.
To avoid this you will need to partition the drives using GPT. GPT is supported by windows 7. If you use a PC with UEFI rather than a BIOS you can even boot from it. (If you have an old BIOS rather than UEFI it usually does not always work.)
If you are using the SSD as OS disk then booting should not be a problem, neither from BIOS or EUFI. After you have installed windows you can go to the disk manager, partition both 3TB drives with GPT and set up a mirrored volume on them.
(Note, leave the BIOS in AHCI mode for this. Not in RAID mode.)
[Edit]
I just saw Sathya's extension to goobers answer. Nice. :)
Test both that and mirrored volumes though. There should not be a speed difference, but that is theory. And as they say "In theory, there is no difference between theory and practice. But, in practice, there is." And that practice might even vary per chipset and driver version.
This page, especially the answer by Sean showing step-by-step instructions, was brilliant! I basically followed the steps above to get my system up and running, but just wanted to add some extra info about my setup in case it is helpful for other folks.
System Configuration:
Because of the HD size, I couldn't get Windows to install. Before continuing, please note that I wanted to install Windows on a 500 GB partition (not the entire 4 TB).
MB instructions says that when installing with Windows 7, there is no need to install a separate RAID/AHCI driver. I found this to be false because when I tried to install using the Windows disk without "Loading Driver" as mentioned above, my HD was split into two drives, each about 1.7 TB, instead of one 4 TB logical drive. I tried both the Intel RST Standalone driver mentioned above and the Intel RST driver provided by Gigabyte ([DVD Drive]:\\BootDrv\iRST\
). Both works fine. In the end, I used the driver provided by Gigabyte. Regardless, to see one 4 TB logical drive, the instructions that mention "Loading Intel RST Drivers must be followed, regardless of whether you end up using the Intel or Gigabyte driver.
In the instructions, there is one point where it says to use the "UEFI BIOS again". This was a bit confusing since UEFI is a bit new to me. There are plenty of other places to read up on the theoretical background so just for practicality, it basically means when choosing the boot drive, make sure to boot off of "UEFI: DVD/CDROM". Also, make sure that when you are creating the partition that you want to install Windows on, there must be 3 partitions:
Partition 1 - System
Partition 2 - MSR
andPartition 3 - Primary
,in that order. Installation should be performed on Partition 3 - Primary
. In my case, since I wanted to install on a 500 GB partition, I specified 500 GB when creating the new partition. There are two super helpful pages describing How to Install Windows 7 Using the UEFI and How to Do a Clean Installation with Windows 7.
Once I was able to figure out the proper RAID settings, loading up the right RAID drivers, and setting up the partitions correctly, Windows would start installing. However, during one of its reboots, Windows would show the blue screen of death (BSOD) and I couldn't continue. When cruising the net, there are a lot of suggestions on what could be wrong. Basically, there isn't one specific cause since a BSOD is pretty vague. However, in my case, the only two adjustments were the following:
Hope someone finds this helpful and saves you a few hours of head-pounding! Thanks again to the other contributors for the help!
I'm guessing you want to install Windows to your SSD and have your RAID array for your data drive. If Windows installer is not seeing this drive, and is seeing the RAID array incorrectly, then you'll need to load the correct drivers for the controllers as the first step in the installation process. It's been a while since I did a Win7 install, so I can't remember the specifics, but there should be an option early on to load additional mass-storage drivers.
