Normally I can work through most Windows issues and come to some sort of repair or fix option but I have one in my possession that has got me a little stumped.
Owner of laptop reports the following:
I get the laptop and confirm on startup that in fact after the Toshiba screen, OS fails to load, no errors black screen w/ blinking cursor.
I attempt restart, F8 to try to go into Safe Mode. The same, black screen w/ cursor
Run Windows 7 (64Bit) Recovery console from CD (It's just the recovery console, no OS to load) (Have one for all OS from XP up to 7 32bit and 64bit where applicable) Chose run from Command Prompt, it goes into Command Prompt fine. CD to C: and run chkdsk /r I receive no errors after this ran for a couple of hours. Rebooted and still same blinking cursor.
Booted back into Recovery Console. Attempted to restore from previous day. Chose last restore point 2/12/2012. Failed to restore. Error code 0x80000ffff which I am sure some of you have seen before. I have never found exactly what that error code is supposed to mean. Other restore points yield the same result.
Booted Parted Magic (Linux) CD, looked at partitions to see if there was a recovery partition. Ahhhhh, there was a 9 GB HDD Recovery Partition. Looked online to find out that the "Secret Squirral Handshake" to get into the HDD Recovery Partition on a Toshiba Satelite was "Hold the '0' key down while turning on the laptop. Release at Toshiba screen and then proceed to tap '0' key until it goes into the recovery suite"
I had no intention on restoring the system, just wanted to see if it would go in. Only thing different was the blinking cursor became a solid non blinking cursor. So it looks like you can't even get into the Recovery Partition to restore to factory settings if it came to that.
So at this point, I plan on running a memory test this evening. Let it run a few times to see if it could be memory related (I doubt it) but do not want to leave no stone unturned. I will then work on getting the owners important files off the HDD (just in case) no, he had no backup what so ever.
So, I am up for any and all suggestions you may have.
Thanks and All the best,
