BSOD after restart, unmountable boot error 0x000000ED

[DrPikachu64]

Yesterday, after bringing my laptop back up from sleep mode, it was running extremely sluggishly. So I closed all open programs, and restarted it. But then, the BSOD popped up, with technical information as follows:
*** STOP: 0x000000ED (0xFFFFFA8004A016C0, 0xFFFFFFFFC0000185, 0x0000000000000000, 0x0000000000000000)

I was able to create a USB boot of my OS, along with a System Repair disc off of another laptop with the same OS. However, when trying to repair it, the System Recovery list displaying the OS available is empty.

Any help would appreciated at this point. I'm really starting to lose steam here doing this on my own...

You could follow steps mentioned in this tutorial: http://www.sevenforums.com/tutorials/219533-troubleshooting-windows-7-failure-boot.html

Update:
After running System Repair and Chkdsk, I can access the Welcome screen, but nothing further yet, as the system stalls upon logging in (even in Safe Mode).
The system itself is still extremely sluggish, but at least I don't have the BSOD pop up now.

Do you have access to another computer right now? If so, download Partition wizard Bootable CD (the last one in the link). Burn it in a blank CD or in a USB flash stick.

Boot into Partition Wizards GUI following this instructions. When you are on the last screen, take a camera snap of the screen and upload the snap here.

We need to see the parameters.

According to Carrona.org, STOP 0x000000ED: UNMOUNTABLE_BOOT_VOLUME
Usual causes: Hard drive problem, File system problem, Improper boot parameters

Also try SFC /SCANNOW : Run in Command Prompt at Boot.

First mark the recovery partition as active. Follow the method three of http://www.sevenforums.com/tutorials/71432-partition-mark-active.html

Then run Startup Repair for three separate times, with restarts after every single run.
Startup Repair: Run three separate times.

As another and elaborate try, follow it what koolkat77 already suggested.
Troubleshooting Windows 7 Failure to Start

I marked it as active, but after I applied the changes, another disk appeared on the list:
Capacity--7.48 GB
Used--3.17 GB
Unused--4.30 GB
File System--NTFS
Type--Primary
Status--Active
The disk is unnamed.

Is this natural?

Another snapshot please?

Do you have any pen drive etc connected?

Anyway, my earlier instruction seems to be a bad one. A fat32 disc should not be a boot drive.

Mark the OS partition back to active. And then run Startup Repair for three separate times, with restarts after every single run.

Does it work now?

Here you go.

Disk 2 is most likely the usb disk. Why make the RECOVERY partition ACTIVE? What are you trying to achieve by that?

 

[DrPikachu64]

Alright, I left the settings as I originally found them (set OS drive to Active, and set Recovery drive to Inactive and Hidden), and started the first Startup Repair run.

The "unknown" drive was actually my Windows 7 installation dongle I made. I must be more frazzled than I thought...

With System Repair you mean http://www.sevenforums.com/tutorials/681-startup-repair.html ?
Did chkdsk fix many errors? Do this again from recovery environment->command prompt:

chkdsk/f  c:
chkdsk/f  d:

no errors anymore?

dir c:\users
dir d:\users

Is the OS disk called C or D in recovery environment?

run startup repair 3 times with reboots in between. Click on "view diagnostics results" or something like that after startup repair finishes. It lists the tests it performed. Which tests have not status 0x0 (means success so no problem) and what is their status?

 

[DrPikachu64]

I'll run chkdsk again if the triple Startup Repair doesn't do the trick, but it was running extremely slowly right before I made that Partition Wizard disc (about 1.5 files in the index per minute).

chkdsk very slow (correct?) . I think your disk is dying. Do you have a backup already? Make it using Macrium Reflect Free for example. http://www.sevenforums.com/tutorials/73828-imaging-free-macrium.html
Take the winpe version and burn the ISO. Boot from the DVD

First Startup Repair run completed, all error codes at 0x0, root cause is stated as "unspecified changes to system configuration".

Starting the second run.

dir c:\users
dir d:\users

that's not the full text!! It must be something like:
"Root cause found: Unspecified changes to system configuration might have caused the problem. Repair action: System files integrity check and repair. Result: Failed. Error code = 0x490.

Please post whole text
