Windows 7: Drive letters change & ntoskrnl.exe missing or corrupt

Drive letters change & ntoskrnl.exe missing or corrupt

Hi,

New to the forums. Could not find a solution to a current issue I have created. There are similar threads but nothing seems to fully address this maelstrom of screwed I've designed.

Problem: Receiving the "ntoskrnl.exe is missing or corrupt" error when I try to boot from my Windows 7 x64 drive. After running the repair disk a few times I then get a message stating "Windows could not start because of a computer disk hardware configuration problem." When I fix that it goes back to the NTOSKRNL.exe error. Also. My drive letters are all changed and I cannot seem to easily change them back. My storage drive is now viewed as foreign as well. Currently inaccessible.

Drive info: 60 gig SSD - Windows 7 Ultimate x64 - Basic Disk
1 TB - Storage drive I had been using with Windows 7. Dynamic Disk
320 gig - HDD - Server 2003 & XP Home edition SP3. Basic Disk

How this started:

I had been using the 60 gig SSD as my boot drive for Windows 7 for 2 years. I was also using a 1 TB storage drive. I had made that a dynamic disk when I installed it because it was supposed to be part of a RAID originally. That never happened though.

There is an older Dell comp at my house I've been using as a practice box for Server 2003. I bought the new drive to load Server 2003, '08, and Virtual Server on my faster comp. This is when trouble started. (I have since learned the rules on installing multiple Microsoft OS's on the same system.)

When I was installing 2003 it asked to store files on the storage drive. No idea why it needed to do this. I said no. Powered off. Opened the case. D/c'd the storage drives SATA cable. Tried again. Installed with no problems. Loaded drivers, played around for about 5 minutes. Shut down. Reconnected the Storage drive's cable.

Powered back on later. Windows 7 was no longer an option to boot through any menu. D/c'd the Server drive's SATA cable. Tried booting again. That's when the NTOSKRNL.EXE error first appeared.

Eventually plugged everything back in. Loaded up XP on the new drive as well. Server 2003 stopped being bootable. Went into Disk Management console. Drive letters had all been rearranged. Server 2003 partition was now drive C:, XP partition was drive F:, and the SSD is now drive G: . The 1 TB storage is just shown as 'foreign.'

The SSD had been C: and the storage drive had been F: before all this nonsense started.

So. Does anyone have some suggestions? I tried the MBR fix for Windows 7. No dice. Windows 7 actually doesn't appear in the list of operating systems shown in Step 3 of that tutorial. Currently considering the fun process of converting the storage disk from Dynamic to Basic so I can at least see it. I'm concerned about losing everything on it though. Been too long since a backup.

Feel free to toss jokes around about the mess here. But if you have useful advice I'd like that as well!
