Advanced Boot problem with disk reverted from RAID 1 (Files are ok)

Screenshot from disk management(from former RAID1):

This is what happened>

I had RAID 1 running on Intel Matrix Storage,(Win 7 Pro x86)
then the software failed first with one then with the another disk.

I use ASUS P7P55D PRO Motherboard where I had two
WD Green 1 TB in RAID 1 (Model> WD10EADS-00L5B1)
running.

After failure disks were checked with Linux, and they were healthy and no data lost.

So far so good, I made a backup of the files and now try to boot, but boot fails right after windows 7 logo animation, it shows blue screen. I tried to fix issue with Windows RE (The automatic repair). No help with that.

I'm not familiar with cmd repairing from the installation DVD nor from Hiren's Boot CD 10.1.

I'm thinking the problem could be with the partitioning, but I've got no idea how. Both disks have two partitions:
1:System reserved (105MB or so) NTFS > Partition Type: HPFS\NTFS (0x07)
2ata 1TB NTFS > Partition Type: HPFS\NTFS (0x07)

Advice appreciated

#EDIT# Advice for everyone, don't use software raid for OS buy a NAS instead, and install OS to SSD or other disk and leave the RAID for Hardware based solution. It'll save you a lot of time.

Hi Tonza,

Ouch : another RAID problem....we see lots of these here.

I'm not sure that you can boot from either one of those disks without formatting & installing again. I assume you reverted to IDE or AHCI controller in the BIOS, when you tried to boot from one of the single disks?

Mmmmm....I think the problem is that the registry entries will still show the controller as RAID. Since the BIOS is now AHCI, I see some conflict.....and maybe Windows see it too......but I can't really be sure.

Best to wait for some one more experienced to look at this, but I suspect you may have to install from scratch.......

Sorry I couldn't be of more help,
Golden

Unlucky. For what its worth, the performance of a single SSD far outstrips any RAID, even RAID0 using 15K rpm SAS drives. I have a 60GB OCZ Vertex 2..............it is blindingly fast!

Oh....one thing you could try, assuming that the problem is the RAID reference in the registry, and that you can get access to the registry of course....

Change from IDE to AHCI Mode after Installation

Information: AHCI stand for Advance Host Controller Interface. AHCI is a hardware mechanism that allows software to communicate with Serial ATA (SATA) devices (such as host bus adapters) that are designed to offer features not offered by Parallel ATA (PATA) controllers, such as:

• Hot-Plugging
• Native Command Queuing (NCQ) -might improve computer/system/hard disk responsiveness, especially in multi-tasking environment

You can read more about AHCI mode HERE

Instruction: There is one way to fix this, although you need to have knowledge of registry editing.
The detailed steps from Microsoft website are as follows:

• Exit all Windows-based programs.
• Press [Win] + R or take the RUN option from the start menu.
• Now type regedit there and press Enter Key to open up the Registry Editor Window.
• If you receive the User Account Control dialog box, click Continue.
• Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\msahci
• In the right pane, right-click Start in the Name column, and then click Modify.

• In the Value data box, type 0 [3 is default], and then click OK.

• On the File menu, click Exit to close Registry Editor.
• Restart your computer
• Go to BIOS and enable AHCI, Save & Reboot
• Another restart will be required to finish the driver installation.

I have exactly the same one.

Very nice - you are going to be very glad you got that one.
