Windows 7: Windows failure to start, Repair fails, cmd can only see X drive

Boot into BIOS setup to see if HD is detected and set to boot first (after disk drive).

If so then work through these steps for Troubleshooting Windows 7 Failure to Start
starting with the HD test - use SeaTools for DOS | Seagate extended CD scan.

hi, thank you - all the info at the seatools site seems to start with installing the software which of course i can't do -- what should i be copying to external media and i assume i have to make it a bootable thing on its own?

the bios does detect the HD, and it will boot the HD first after removable media.
if i go into the startuprepair though (which breaks the communication to the drive somehow) and let startuprepair reboot, then the bios won't recognize the drive. then i restart again and it will recognize it.

SeaTools for DOS | Seagate
burn to CD with Windows Image Burner or ImgBurn, boot to run Extended test.

If you know your HD make, use it's own diagnostics CD download.

Working thru it! So far:

SeaTools -----
Detects device, SMART is supported, enabled, and has not been tripped. DST supported. Logging feature set is supported. POH 3900 Results: Short DST Passed, Long Test Passed

Windows defender----
Windows defender offline cannot be started - unable to detect a windows drive. This could be due to missing drivers, an encrypted drive, or a corrupted windows installation. (This drive has hardware encryption out of the box as I understand it, if that could be the reason.)

Startup repair---
I've already written above what goes on with startup repair, but I did it again here to make sure I had 3x in a row. No change in behavior.

BootRec---
Yay shift+F10! I got to a dos prompt without going THROUGH startup repair, which I hadn't been able to do! I can see my HD and navigate around in it. I used the commands
Bootrec.exe
bcdedit /export D:\BCD_Backup
and got the "successful" message. BUT, when I go to D there is the BCD_Backup file but no Boot folder to use the command
cd Boot

There is a D:/Windows/Boot folder, but because I don't want to screw anything up I want to make sure that's what I want? Should the previous command have made a boot folder at the root of the drive?? Thank you!

The drives may have different letters in WinRE. Just complete the Commands. Then try Startup Repair again as it may now work.

If you cannot boot into Safe Mode to run Malwarebytes scan, run one of the other Bootable AV's like BitDefender.

Hey, it wasn't that the drive letter was different that threw me, it was that the Boot folder that was shown is supposed to be at the root of the drive, but I don't have a Boot folder there. I have one in the Windows folder. Is that the one I am supposed to use?
(the command list at the link you gave me are as below)
  • bcdedit /export C:\BCD_Backup
  • c:
  • cd boot
  • attrib bcd -s -h -r
  • ren c:\boot\bcd bcd.old
  • bootrec /RebuildBcd
If i do this exactly (using D: vs C) then it fails because I have no folder that is D:\Boot.


As I posted above, the bootable windows defender cannot run. It failed to find the drive.

Again, run one of the other bootable AV's as it may not repair if its' infected. You can also rescue your files with several.

Startup Repair may work then after confirming the Active partition.

Then skip the bcd backup and run the rebuild command, and

bootrec /fixboot
bootrec /fixmbr

I ran the bootable bit defender - it gave me the 'successful' result but it only scanned 42 files --> it did not scan my hard drive. After that I opened GParted in the little OS bit defender loads - it says "failed to mount 119G Volume - the enclosing drive for the volume is locked".

Kaspersky's rescue CD is reporting my drive is in hibernate mode and that mounting the file system may damage it.

So my quick question now is should I try the bootrecord fix first to see if that helps (can it hurt, if I haven't cleared a potential infection?) or should I let kaspersky try its thing? I will go ahead and load the next bootable AV in line in the meantime. Thanks!

How old is the OCZ SSD drive? If less than a year contact their tech support for help running their own Diagnostics on the drive to get a possible RMA. If not study the Support webpage for your model closely for diagnostics, firmware, reported problems. This may be a known condition. I don't trust the Seatools results with that behavior from the various repair disks.

Ughs. I will look again for their own diagnostics and I bumped my thread at the OCZ forums too.

For what it's worth, the AVG bootable av can see the drive and scanned it and found no infections.

BUT it also has a registry utility (which is what startuprepair found as my root cause). When I open that utility I get this message:
----------------------------------
reged -l "/mnt/sda1/Boot/BCD"
"/mnt/sdda2/Users/Default/NTUSER.DAT"
"/mnt/sda2/Users/myusername/ntuser.dat"
"mnt/sda2/users/myotherusername/NTUSER.DAT"
"HKEY_..."
"\"
" > "
"/opt/avg/arl/reged.out":
Could not read file, got 8192 bytes while expecting 28672 Unable to open/read hive /mnt/sda1/Boot/BCD, exiting..
-----------------------------------

Going into a DOS prompt and looking in my system32/config folder, my SECURITY file is 28,672 bytes... not sure what is stopping it from reading that. All but one of my RegBack folder's files are the same size and have the same timestamp (close to the failure time I think). The SYSTEM file in my config folder has a more recent timestamp of 2 days ago... not sure what changed that.

Not sure if it would help since my RegBack files are the same size and date as my config folder files for the most part, but I can try these instructions to manually replace the files here?

Thanks for all of your help! Hopefully OCZ can give me more info if I can't fix it - I keep going at it bc I feel I must be missing just that ONE thing more... prob should give up though...
