Windows 7: Serious Boot Catastrophe

07 Feb 2014   #31

Windows 7 Ultimate x64


I have a blank drive lying around. Would it be possible to copy out the contents of C onto this drive, make a clean install on the old boot drive, then use copy out the files and registry from the old drive to the new drive, overwriting, to essentially "restore" programs and settings from the original installation?

2nd try with Win7 SP1 liveUSB:

RE detects my installation as "Windows 7 Ultimate 64-bit (Recovered)". However Startup Repair "is unable to repair this computer" on the first try. Next 2 tries result in "Startup Repair could not detect a problem".

Diagnosis and repair details:
Last successful boot time: 2/5/2014 3:31:49PM (GMT)
Number of repair attempts: 12
Session details
System Disk = \Device\Harddisk1
Windows directory = G:\Windows
AutoChk Run = 0
Number of root causes = 1
Name: Boot status test
Result: Completed successfully. Error code = 0x0
Root cause found:
Boot status indicates that the OS booted successfully.
Name: Fallback diagnosis
Result: Completed successfully. Error code = 0x0
Root cause found:
Unspecified changes to system configuration might have caused the problem.
There were alot of other entries in the log, but only those with remarks (above 2) are shown.

After finishing 3x attempted Startup Repair, I tried to start Windows again but failed at logo animation.

Did you unplug all other drives to run the three Startup Repairs, with only System Reserved marked Active?

If it won't repair after doing that, as well as Rebuilding MBR first, then it is likely corrupted beyond repair.

However Startup Repair should offer to System Restore during it's run. Did it do this? If not then run System Restore from System Recovery Options.

One other thing I try as a last resort when browsing in to rescue files if necessary using Copy & Paste - in Windows Recovery Console is to copy the boot files from System Reserved to C, next Mark C Partition Active, then run Startup Repair - Run 3 Separate Times. Unplug all other HD's when running Startup REpairs.

Since a 7B error can mean infection of boot sector OR a hardware error, run the AV scans and hardware tests at the beginning of Troubleshooting Windows 7 Failure to Start. If you complete all of the steps there then you've done everything that can be done, leading up to if necessary rescuiing your files to do a perfect Clean Reinstall - Factory OEM Windows 7 which is same for retail.

Windows 7 Ultimate x64

Good morning Greg,

Good news. At about the same time as when you posted, a fellow user on another forum posted a suggestion to check if my BIOS was set to IDE or AHCI mode. I do not remember ever touching this setting. However I found it in AHCI mode and set it to IDE. Seeing how I have scoured the very edges of the internet for all sorts of complex solutions, I was understandably skeptical that such a simple step could fix my problem.

Lo and behold, there it is. I have never been so delighted to see a Windows startup logo animation in my life.
(All the messing about did screw things up a little though; I had to reactivate Windows.)

Nevertheless, I must thank you for your time and patience in assisting me throughout these 2 days, even when I was frustrated at times. If you like, PM me and I will send a small token of appreciation your way.

Nick -

I did notice you reported back your SATA setting was AHCI which is what it should be set at for using all of the features of the SATA controller. I guess your install was instead done to IDE. Glad you found the solution.

Remember when reinstalling to choose the more modern AHCI setting, delete all partitions on the HD. You can also change it now to AHCI : Enable in Windows 7 / Vista - Windows 7 Forums. Set a System REstore point first. System Restore Point - Create

Thank you Greg. It has been so long ago when I installed Win7 (it's really, really stable and reliable) that I forgot what setting was used. The information on how to switch over to AHCI is very useful, I will carry them out when I have more free time. For now, back to work!

Once again, thank you so much. I appreciate it.
