Windows 7: Startup Repair to infinite reboot loops, Repair errors 0x5 & 0x490

Startup Repair to infinite reboot loops, Repair errors 0x5 & 0x490

Firstly, thanks for reading.

My PC runs Windows 7 x64. I built it myself about a year ago for gaming.

Occasionally running games I would BSOD and it would suck. I'd update all my drivers or try some game-specific fix and usually if I didn't fix it, I would just start playing something else until I remembered it and by then, some Windows update or my own tweaking or just divine providence would have stopped the bluescreens. A few games, like GTA IV, Bioshock Infinite and Spec Ops: The Line remain unplayable for me, as they constantly bluescreen no matter my alterations or updates, but that's another story.

My problem is with Startup Repair. I was playing Max Payne 3 last night, all was well, then BSOD. To note, I never actually see the blue screen, the video cuts and the audio stutters for a moment, then the computer restarts. But in the .dmp files they're always reported as BSODs. Anyway, I restart and do some other stuff, then turn it off for the night. Today, I turn the PC on, and it prompts me to Start Windows Normally or launch Startup Repair. I chose to repair, thinking it was probably time I let Windows have a shot at it for once.

Well, I'm sitting a feet away and watching the screen right now, and it's going through the third consecutive automatic repair. In the past few hours I've run memory diagnostic, gone through the Startup Repair Infinite Loop Recovery thread with the MD mybackup stuff, attempted chkdsk (can't due to a lack of write privileges, even after DISKPART -> ... -> attribute volume clear readonly), re-seated the hardware, disconnected the case fans, removed unnecessary USBs (took out Wacom tablet and 360 controller, left Logitech G5, network adapter, and Logitech keyboard receiver), and done two system restores to several days earlier.

While I was typing, the next System Repair completed. I'm looking at the diagnostic details now, and all the actions completed successfully, excepting where the Root Cause was found. It says the boot manager failed to find the OS loader. File Repair failed, with error code 0x5, and Boot Configuration Data Store Repair failed, with error code 0x490.

Now everything I've tried has been sourced from threads like these, where users solved their issues. Sorry to sound pressuring, I'm just hoping to end this nonsense. Thanks for the consideration.

Post back a screenshot of your maximized Disk Management - Post a Screen Capture Image - Windows 7 Help Forums so we can check your disk config.

If you can complete collecting the info requested in Blue Screen of Death (BSOD) Posting Instructions - Windows 7 Forums post it up in Crashes forum if this thread is not moved there.

Otherwise work through these same steps for Troubleshooting Windows 7 Failure to Start which try everything to repair unstable Windows 7 including hardware tests if indicated, and if necessary getting a baseline perfect Clean Reinstall.

You also want to do your System repairs only from the Windows 7 DVD (provided) or System Repair Disk, not the automatic repair which depends on possibly corrupted files.

I would do steps 1 & 2...but the PC is in a reboot loop. If I could get to Disk Management or anything else, I wouldn't have a problem.

I've tried to access the F8 advanced boot options menu, but it just won't run during startup. I can access the setup menu and the boot device menu, but I'm not able to access even safe mode, so I'm locked out of any OS operations.

So, I guess I'll try to create a repair disk.

The Troubleshooting steps show how to access your disk picture using Partition Wizard, so post back a camera snap of the maximized windows showing all listings and map if possible.

The steps also show you how to access and rescue your files if necessary, so you can check for %systemroot%\minidumps or c:\windows\minidumps for the BSOD file to post up in Crashes forum.

Otherwise work through the other steps to see if you can resolve the crash loop or rescue your files and do the Clean Reinstall.

Sorry, missed that about the Partition Wizard.

Okay, so I've created a bootable PW disk, after burning the x64 .iso to a blank CD. Maybe there's a tutorial somewhere that I just can't find, but booting from the CD drive won't work. Instead, I get the startup repair operation.
To clarify, I can use F11 to access the boot options, and choose either the SATA hard drive or the CD/DVD drive. But choosing the disc drive doesn't seem to change anything afterward; either choice leads to "Windows is loading files..." -> Startup Repair. I don't even receive a "Press any key to boot from CD drive..." prompt.

On the back burner, my x64 repair disc can be booted to and gives me the same options as hard drive boot, but as you said, from the disc's files. Either way, operations through the repair disc make no difference, either automatic repair or system restore.

What I'm going to do now is burn another PW disc, in case the first one is just being randomly insubordinate. If that doesn't work, I'll attempt a PW USB bootable.

If I'm understanding this all right, hopefully I'll get back with a Disk Management screenshot. Thanks for the info.


Alright. CD wouldn't cooperate, but the USB did.

How did you burn the ISO to CD? Use Windows Image Burner or ImgBurn at 4x speed.

You should get a prompt to "Press any Key to boot disk" if the disk is burned correctly.

Yeah, I was probably using the wrong write speed. Either way, I got the screengrab.

I'm going to follow the rest of Step 9 in the Troubleshooting Windows 7 Failure to Start list, rebuild the System Reserve partition's MBR, then the Windows 7 partition. Afterward, I'll try out the PW Partition Recovery Wizard, unless you have a recommendation.

Setting the Windows 7 partition to Active and booting it won't proceed past a check that tells me the boot manager is missing. It prompts me to restart with Ctrl+Alt+Del.

Edit 2:
As an addendum, I still can't enter Safe Mode to load the SF Diagnostic Tool and gather the necessary .zip of information for a post in the BSOD Help and Support forum. Is there a way to run it from a USB like with Partition Wizard, or should I just post the details of what I know, like this thread?

You want to Rebuild MBR and then if necessary run Startup Repair - Run up to 3 Separate Times with the Active flag both on System Reserved and then C, to see if either will start. This sequence is clearly specified in the tutorial, which requires absolute attention to detail.

Now, I've run Startup Repair four times while the Reserved partition is flagged Active and after rebuilding MBR. Unfortunately, no dice. As I wrote above, I can't boot at all while the C partition is flagged Active; instead it tells me the boot manager is missing, and asks me to restart with ctrl+alt+del.

Also, two questions

1) I ran the repair four times before I read your post, and the tutorial given. That describes using the command prompt with DISKPART to flag actives; does it make a difference if I've already tried the method with Partition Wizard?

2) The Startup repair process, if I'm booting to the repair disk to perform it, should I set the default boot device to the CD/DVD drive while I let attempt to repair? Would using F11 to select the drive each time interrupt its repair behavior, or is it irrelevant?

You need to also Rebuild MBR and run three Startup Repairs after moving the Active flag to C. Just rebooting won't do it as it has no System boot files, written during the 3 repairs. You can always use either Diskpart or Partition Wizard CD to mark Active.

It's best to keep the HD involved set first to boot with all others unplugged, then trigger CD or DVD using one-time Boot menu key.
