7 HP x64 - Startup Repair Loop, NoRootCause
Hey Guys,
Have a friend that has given me their PC to fix. It's running Win7 HP 64 bit and is stuck in a Startup Repair Loop. None of the Safe Mode options boot, neither does the Last Known Good Configuration option.
I have tried using a Win7 HP disc to repair Windows, run a chkdsk on the OS drive, scanned the drive for any viruses with and AVG rescue disc. I have also removed the rive and plugged it externally to a working PC and found all files to be intact, or so it would seem.
I have read a couple of forums and tried a few other things like this >> Startup Repair Infinite Loop Recovery which still does not work.
Unfortunately no restore points were created and I do not have access to replace all of the programs & games that my friend has installed.
Does anyone know of any other options?
This is the only information I get from the system after the failed Startup Repair.
Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: Unknown
Problem Signature 04: 21199410
Problem Signature 05: AutoFailover
Problem Signature 06: 30
Problem Signature 07: NoRootCause
OSVersion: 6.1.7601.2.1.0.256.1
Locale ID: 1033
I have noted that Problem Signature 6, increase each time the Startup Repair fails.
I have also tried an MBR Rebuild through Easeus Partition Master and this was still unsuccessful.
I have some more information below in regard to the startup repair.
Root Cause Found:
----------------------------
The partition table does not have a valid system partition.
Repair Action: Partition Table Repair
Result: Completed successfully. Error Code 0x0
Time Taken = 2356ms.
I have a bunch of tests that Startup Repair has run, all with the same result, so I will just list the Test Name and Time Taken.
1 - Check for updates, 0ms
2 - System disk test, 16ms
3 - Disk failure diagnosis, 31ms
4 - Disk metadata test, 0ms
5 - Target OS test, 156ms
6 - Volume content check, 78ms
7 - Boot manager diagnosis, 0ms
8 - System boot log diagnosis, 0ms
9 - Event log diagnosis - 0ms
10 - Internal state check, 0ms.
Please note that the above 10 Tests all had the same result of
"Result: Completed successfully. Error code 0x0"
At the very end of all the test result, Startup Repair had the following.
"Root cause found: Startup Repair has tried several times but still cannot determine the cause of the problem."
I'm at a loss for what to try. At present I am looking at Using a Boot CD (Hirens or UBCD), however I have never really used this tool before and am not completely confident with it.
Please let me know if anyone has a suggestion other than a clean install..
Thanks!
Alexx
