Missing Operating System/Startup Repair Failure

[Jmosph]

Hi, I apologize if this isn't the right subforum but I saw a couple old posts about this in General.

Yesterday one of my kittens knocked my laptop off my chair causing it to hit my PC tower on the way to the ground. My tower immediately froze and when I went to restart it manually I accidentally pushed the reset button instead. (It's the button on the right) Upon doing this my computer restarted and gave me the Missing Operating System error.

Since then I have tried several things from pressing F8 and specifying the drive to boot from, to entering several commands listed here to booting from my Win7 disk and running startup repair. This final option I did a couple times last night rather uneventfully but today it failed. Under problem details it gave me this:

Problem Signature:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 0.0.0.0
Problem Signature 02: 0.0.0.0
Problem Signature 03: unknown
Problem Signature 04: 0
Problem Signature 05: unknown
Problem Signature 06: 1
Problem Signature 07: unknown
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033

I don't know if this information is relevant or helpful but I thought I'd include it anyway v0v

edit: I just told Windows to go ahead look for a solution and it claims I have an attached device that needs to be removed, which I don't.

edit2: Would a total reinstallation of Win7 fix the problem?

Any advice is appreciated.

First, I would open the tower and check to see if all the connections to the hard drive, etc. are still secure.

Yeah I did that too and everything seems ok but I'm not entirely sure. I have a couple buddies who build and might get them to look at it.

Boot to system recovery options (OPTION TWO) http://www.sevenforums.com/tutorials/668-system-recovery-options.html and select "command prompt"

dir  c:\users
dir  d:\users

Hi there.

Ensure that the boot disk's partition is marked as ACTIVE although why this should have changed ???? == Beware of "CAT POWER" !!!!!.

dir  d:\users

for dir c:\users I get: The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted.

for dir d:\users I got: The disk structure is corrupted and unreadable.

in that command prompt do:

diskpart
select disk 0
list part
exit

How many partitions?

diskpart
select vol c
detail part
select vol d
detail part
exit

File system is nfts? post camshot

Done, although I have two ~120 GB SSDs that have always acted as one disk and this failed on the first saying 'There is no partition selected' when I tried to select one but it worked for the second disk. Entirely not sure if this makes a difference.

diskpart
list vol
exit

What drive letter has the win7 partition (look at the size to determine what it is)

Are the two SSD's mirrored or striped? So ... is it RAID 0 or RAID 1?

I don't know, what's the best way to find out?

don't you know your own configuration?

A buddy of mine built the machine and when I bought it off him I just reinstalled the OS. If I had to guess I'd say RAID 0.

Update, I cleaned and rechecked everything inside to make sure nothing is unplugged/loose etc. Everything seems fine although now when I turn it on it'll start up, power down, come back one, power back down and then finally come back on. This is measured and repeated in exact intervals for exactly two times. My motherboard is a Sabertooth X58.

Additionally I can't run a memory diagnostic, it gives me an error that I must do it manually via the Win7 CD; however this is what I am already booting off of.

If the computer is fine insofaras hardware is concerned would reinstalling Win7 probably fix whatever software issues I have?

Update 2: On looking at some advanced startup repair logs I found this as well.
"Root cause found: Partition table is corrupt on disk/Device/Harddisk0."
Repair action: Partition table repair
Result: Failed. Error code = 0x490
Time Taken = 587032 msedit: If I go to do a Custom Install of the OS it only see 119 GB of space in terms of partition options, which is only one of my SSDs. I think something must be wrong with the other. I know which SSD works and which one doesn't as well.

Unplug the non-functioning SSD, reset SATA controller in BIOS setup to AHCI and do a Clean Reinstall Windows 7. I would do this yourself so you learn more about what works best to obtain and maintain a perfect Win7 install.

We see nothing but problems with RAID here, Week after week since beta in 2009: Never one single report of good RAID, only one mess after another - almost all resulting in lost data even though the first letter stands for "Redundant."

Redundant disaster!
