URGENT-Blue Screen/Boot-up Crash/ALL Repair/Install Fail

[armsys]

Dell T3500 2 15.T hard drives with RAID 0
Windows 7 x64 Ultra
My newly bought T3500 has been unable to boot up since Sunday (Apr 25).
Whenever it boots up, it crashes and yields a blue screen.
Dell tech support has been unable to resolve the issue over the phone and refused to deploy a Windows 7 specialist to resolve it on site.
Using Win 7 Ultra CD, a repair attempt yields the following log:
Root cause found:
Unknown Bugcheck: Buckcheck 6b, Parameters = 0x0, 0x0, 0x0, 0x0,
Repair action: System files integreity check and repair
Result: Failed, Error Code = 0 x490
Time Taken = 651039 ms
Issues:
1. Boot-up results in blue screen.
2. Unable to repair with the Win 7 CD.

It appears Win 7 can't access the boot drive.
It appears most system files are inaccessible.
Days before it could boot, it has the following issues:
1. sfc yields: Windows Resource Protection could not start the repair service.
2. Repair Install yields: Windows could not retrieve information about the disks on this computer.
3. Windows Installer: The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance.

Please help.

There's quite a bit about the Stop Code 6B here, but I doubt that will help you.

Personally, I'd reject the Dell as unfit for purpose (or under whichever consumer protection legislation you have) and ask for a refund or a replacement. If nothing else, that might stir Dell into action!

Hi John,
Grateful for your fast rescue.
In the total absence of Dell tech support, so far I succeed in:
1. Creating a bootable Win 7 x64 Ultimate USB Flash Memory. Surprising, it works brilliantly.
2. With MBRWiz64, I discovered that C:\ was set inactive.
3. After C:\ is set Active, when booting up, system error: bootmgr is missing.
4. After copying bootmgr in c:\, when booting up, the Win 7 still crashes and yield the blue screen.
5. In c::\Windows\MiniDump, I can't find any log.
6. Now, while typing this post, Win 7 failed to repair and yielded the following Problem Signature:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 0.0.0.0
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21200983
Problem Signature 05: 16
Problem Signature 06: 0x6b
OS Version: 6.1.7600.2.0.0.256.1
Please help.

If practical, I would get a replacement hard drive and drop that in, then try a new install.

After chkdsk c: /f
ChkDsk produces the following message:
Failed to transfer logged messages to the event log with status 50.

Please help.

Leif,
Thanks. But it isn't a simple and easy decision given 3T of data without backup.
The situation is even complicated by RAID 0 linking two 1.5T drives.
Thanks for your help.

This certainly sounds like a faulty hard drive to me. I guess it could be a disk controller fault if you are VERY lucky.
