Windows 7: Win7 Won't Boot, Need Help

Win7 Won't Boot, Textless Bluescreen

Rebooted my 32-bit Win7 HP computer after three weeks of uptime. Right after the bios switches to a pure black screen (right before Windows loads, during the time you would try to bring up Safe Mode with F8) the PC encounters a boot problem. A screen pops up. It has a black border around the entire edge and inside the border is pure blue. There is no text, no mouse cursor, and I know Windows has not begun booting. After a short while, the computer auto-restarts, like it had encountered a genuine blue-screen. Is a textless bluescreen even possible?

Safe Mode cannot be triggered. However, if I load a Win7 Repair Disc, my system will tell me to press a key on the keyboard to load the CD/DVD at startup. If I wait for this message to disappear, and then hit F8 as soon as it does, I am then taken to the Safe Mode menu I would normally expect.

Launching windows takes me to the blue screen/black border I described. If I tell it to enable Windows Boot Logging, the text file it produces (%Windir%/ntbtlog.txt) contains four gibberish ascii symbols. I have a second computer in the home and that file contains text you would expect to see. Further proof Windows isn't actually loading.

On the off chance something was up with my MBR, I ran the Win7 Recovery CD. I waited until the first screen came up where I can interact. Here I pressed Shift+F10 to bring up a command prompt. I typed "bootsect.exe /nt60 SYS /force", rebooted, but same issue with Windows not loading. Went back and I tried "bootsect.exe /nt60 ALL /force", rebooted, same issue.

When I try to used the Repair function of the repair disc, it tries to locate my HD's. Immediately it only shows 1 (there are three and multiple partitions), it is Windows, with 0% for partition size, and unknown for the final column. It searches for other hard drives for five minutes or so and then allows me to select the hard drive from the list and click on Next.

I run the repair function but it cannot find any errors. I also sometimes use a program called WinPE Easy Recovery Essentials. It uses, what I assume is, a Live Linux CD and includes an Automated Repair function for Windows 7. This brings up a list of all of my hard drives, and their sizes are reported properly. However, it claims that not a single partition contains a Windows installation.

This same CD contains a file browser. I can see all of the files on my Windows drive. This is how I checked ntbtlog.txt earlier. My problem is that I have no idea what else I might be able to try to diagnose why Windows isn't booting. Any ideas? Thanks!!

I came across this post about manually fixing the MBR (taking a shot in the dark). It says to load the Win7 Recovery Disc, I open a command prompt with Shift+F10, and then typed "bootrec /rebuildbcd". It waited a bit and then reported that no installation of Windows were found.

If I don't use Shift+F10, just hitting Next instead when the disc starts, it takes forever as described above. Eventually it will time out and allow me to select the drive, click next, and choose Command Prompt from the following window. Exact same result. Is there any way to confirm it is a MBR issue? Outside of WinPE Recovery Essentials, I can't even confirm the Windows drive is there.

Any help would be greatly appreciated! I'm really against a clean install or a repair install that would mess with Windows settings.

I think your disk may be failing.

I performed a diagnostic test on the drive using the utility that came with it. It reports zero errors/bad sectors. I tried the command "bootrec.exe /fixmbr" and "bootrec.exe /fixboot". Both commands said there were successful, rebooted, no change.

A Microsoft article suggested changing the permissions on my BCD Store, rename it, and then run "bootrec.exe /buildbcd". It claimed it should now find an installation if this method will help, but it still returned a result of 0 Windows Installations found.

UPDATE
Going to edit the first post. I said that if I stay at this weird bordered bluescreen, that it never did anything. That has changed. Now it auto-restarts after a short while. Just like a real blue screen. So I'm assuming this is a bluescreen without text? If such a thing is possible. Bluescreen's are the only time that I am aware the computer will auto-restart itself.

I grabbed GParted. On my Windows drive there are two partitions; Windows and a System Reserved partition. Windows was not set to boot, System Reserved was. I checked my other Windows 7 PC and verified that the Windows partition should be set to boot. So I corrected it.

Now it boots to a black DOS screen with the text "BOOTMGR is missing". Windows Repair Disc and WinPE Recovery Essentials still don't see any drives, so they can't fix any errors. Tried running the command prompt commands I described earlier, but not changes to the BOOTMGR is missing situation.

Some OEM computers has some programs on the Reserved partition (like computer health check, disk check, factory recover etc) so it's normal to have this partition as active and even have the Windows boot loader.
Go back and set Reserved partition as active and restore the MBR.

Boot from a win 7 installation disk, go to repair and launch cmd window.
Check your disk. On a cmd window type chkdsk C: /f
Do a system file check. On a cmd window type sfc C: /scannow

If everything fails, you can always reinstall windows.
With the MS iso downloader (https://www.heidoc.net/php/Windows%2...Downloader.exe) download your win 7 OEM brand,
With the Linux, copy the \Users folder and the HP drives folder.
Do a clean install. Clean Install Windows 7
Use your COA stick key to activate.

For the updates:
MS releases SP2 for Windows 7

It doesn't seem unreasonable to try replacing the system partition. Would it be possible to use a system partition from a different installation of windows? I may have a much older back up of the system partition (when I first setup the system years ago) I could use as well. Would replacing it be a viable thing to try?

This system is highly customized. If there is any way to avoid having to lose Windows settings/configuration data via a Clean Install, I'd sure like to try it first. Given that there don't seem to be any reasons supporting that a Clean Install is a must, I'd like to try a bit longer. Any help further diagnosing the source of the issue, would be greatly appreciated. I can do the work, I'm just trying to figure out how to detect the problem.

I can't offer any more information than you have already been given but I would strongly urge you, once you are up and running again to download the popular backup software Macrium Reflect and back up your system using a system image on a regular basis say once a week at least. Then if you have a similar problem in the future you can be up and running again within the hour.

I have read all the posts again.
If your BIOS has a Fast boot option, disable it for now.
You have 4 hard Drives
500GB Samsung
320GB Seagate
1TB Hitachi
80GB Hitachi
In witch one was win 7 installed? How many partitions are on that disk? Who has installed win 7 on it? Is it a OEM computer or build by you?
Is the disk recognized on BIOS?
Before you go further on attempting to recover Win 7 I suggest you to detach all the other data HDD from the MB.
WinPE isn't Linux. Windows Preinstallation Environment (also known as Windows PE and WinPE) is a lightweight version of Windows used for the deployment of PCs, workstations, and servers, or troubleshooting an operating system while it is offline..

With only the Win 7 disk attached to the MB, can you boot from WinPE and launch disk manager?. I began to think the possibility that your Win 7 disk has failed.

Alright, this is the latest turn of events. There is a bit more to go on now (i hope!).

1. The system recovery window, the one with no drives, has an option to load drivers. I clicked that button and in the window that popped up I was able to see that Windows clearly detected all of my drives. They were there, with their files in tact. When I went to the system partition, I found it had an empty temp folder. I have a great track record of not getting any viruses. However, with the drive having no files on it, I ran two separate anti-virus scanners and both reported the system is clean.

2. As I mentioned earlier, even with no drives listed in the system recovery window, I can still click next. This brings up the normal Diagnostic Tools window, and if I tell it to repair errors, it says it can't (don't remember the exact error). But, if at the Diagnostic Tools window, I open a command prompt and type the commands below, I can make a drive active and then the automatic scan will run.

Commands
DISKPART
LIST DISK
SELECT DISK 0 (confirm from list this is WIn7 HD #)
LIST PARTITION
SELECT PARTITION # (replace # with WIn7 part #)
ACTIVE
EXIT

The hard drive with Windows only contains the Windows partition and the System Reserved partition. When I ran the automatic repair on System Reserved, it reported it couldn't repair it. The reason was "NoOsInstalled". Same result for the Windows partition; reason was "BootManagerIsMissing" or "BootManagerNotFound". If you need to know for certain, let me know and I will run it again.

Question
I understand that the system partition can be rebuilt when it has been damaged. No idea what happened, not particularly concerned either. Not if I can simply rebuild it. But if I can't use System Repair to rebuild the system partition, is there another way to achieve it? Would it be possible to simply clone my other working Windows 7 HP 32-bit PC's system partition and add it to the damaged PC?
