Powerfailure during Win 7 64 boot on a dual partition system.
Right after the Windows wording came up, before the logo swirls.

Hung, so I had to force a reboot.

 

Showed: "Launch startup repair or start windows normally?"

I selected Start windows normally (have been choosing that option for the past 8 years on this installation when I get that prompt, oh maybe three times per year)

 

Hung again but this time on the black screen after the logo swirls disappear.

 

I therefore had to force another reboot.

Showed 0x0000006b which means corrupted bootcache.cat. Easy fix, just start using another partition or bootable recoverydisk/usb and delete the bootcache.cat in system32/codeintegrity on the partition showing the error. On a subsequent reboot it will be built again.

Nope.

Problem is I cannot access the boot partition (Win 7 64) to delete or swap this file. I have a secondary partition I can bootup from; D: (Win 7 32) and even a Bootable Win 7 repair USB (Win 32 and 64 versions).

No matter what I do, I cannot write anything to C:

Doing a dir query from an elevated command prompt out of D: or the recovery USB shows:  "The file or directory is corrupted and unreadable."

I then tried Sfc /scannow.  It said it did something, and told me to reboot and run sfc again, I rebooted off the usb drive again but no change.  I then tried
Sfc /scannow /offbootdir=d:\ offwindir=d:windows (remember d: is the primary (problem) partition when booting from USB).  Again it didn't succeed.

I then tried Chkdsk /f d: (again, remember d: is the primary (in my case; problem) partition when booting from USB).  It said:  "The type of the file system is NTFS.  Unable to determine volume version and state. CHKDSK aborted.  Failed to transfer logged messages to the event log with status 50.

So it IS! reading the file system as NTFS.

I tried bootsect and bootrec. /fixmbr, /fixboot. They say operation completed successfully but no change. Perhaps they are simply overwriting the boot on the bootable USB recovery stick X:

I tried X:\>bootrec /rebuildbcd and got:  "Scanning all disks for windows installations.  Successfully scanned windows installations.  Total identified windows installations:0.  The operation completed successfully."

Which is weird, since I have a fully working windows 7 32 installation on the secondary partition d:

(When you boot from a bootable usb your drive letters get messed up though, so
Driveletter C: becomes the usb, Driveletter D: becomes your original main C: partition (the bootproblem in my case), Driveletter F: becomes your actual second partition (usually drive d in windows) and Driveletter X: is the windows ramdisk

Anyhow, then I tried:  Bcdboot d:\windows.  It said: "Failure when attempting to copy boot files."

Finally I tried Bootsect /nt60 D.  It said: "Target volumes will be updated with BOOTMGR compatible bootcode.  D: <\\?\Volume<3c4ecbb8-f805-19e5-9250-806e6f6e6963>>.  Could not open the volume root directory:  The parameter is incorrect.  No bootcode was successfully updated."

So eventhough it is reading the volume, I don't know what to do.

When I run the repair windows from the USB stick I get the windows repair GUI. The little table asking me which windows partition I want fixed does show me my two partitions, but it lists C: 0MB D:100gb, when in actuality it is C:800GB D:100GB

But clicking repair gets me no result, I EVEN have full system restore turned on for the partition in question, but obviously it cannot access the partition to locate and restore the saved files!

So when I try to boot the partition in question I just get a 0x000000f code.

I'm thinking of trying testdisk or Easy Recovery Essentials tomorrow, as these programs GUARANTEE they can fix any partition boot problems not caused by hardware, lol.

I'm sure its a software issue, and my aim is to get the 800Gb partition booting again.

Anyone here have any idea I can try?

Lol, if you read this far you must be a diehard like me.

What does Disk Management have to say about the partition?

 

START | type diskmgmt.msc | maximize the screen | take a screenshot using the Snipping Tool (START | type snip | select Snipping Tool)

 

Attach screenshot to your next post.

Have you bothered to check the functional status of the hard drive via a hard drive diagnostic?

Thanks for the assistance guys. The disk is in excellent physical condition as these attachments show.

 

It really is a software issue. It shows ~830gb free on that disk while in actuality it was around ~139gb free.

I'm now delving into Testdisk and getting in contact with James Litten

So partition wizard after deep scanning is giving me this result:

 

Attached File  Untitled.jpg   94.13KB   0 downloads

 

 

I don't get it. This is just a normal Windows 7 install on a 1TB Western DIgital Caviar Black HD, where I created two partitions using the Windows 7 installer.

 

One partition of 800gb NTFS for my main Windows 7 64 installation, and the second partition of 100gb NTFS for my backup boot Windows 7 32 installation.

 

The 800gb is the messed up one, it had 670gb of data on it.

 

 

Why is Partition Wizard showing so many bootable partitions? Sure I had Daemon Tools, etc installed on both partitions but still, it doesn't explain it.

 

 

I have not write anything to the messed partition yet, I am waiting to hear back from

 

Christophe Grenier, writer of Testdisk, to see if that program can help in this case,

Hi Gold333,

 

Just an observation, but in your disk management pic your (M) drive or 831GB is formatted to raw not NTFS

 

Hedge

 

 

EDIT:- Please  Do Not  just reformat it you will lose data.
