BSOD after restart, unmountable boot error 0x000000ED

DrPikachu64 · 15 Apr 2013

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: Troubleshooting Windows 7 Failure to Boot

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.

Screenshots of both the main menu of the wizard and the properties window are within the .zip.

First mark the recovery partition as active. Follow the method three of Partition - Mark as Active

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.

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?

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?
