I am stuck in a loop I can't seem to get out of. My PC died. I had two drives on it in a dual boot configuration. At least one of them should boot without the other. I think both will boot as long as the correct menu item is selected, but I don't remember for sure. I think I originally set it up with BCD Edit, but it was a long time ago.

 

I have two back-ups of the main drive on other separate drives. When the computer died, I started getting BSOD errors first. They would suddenly pop up at random intervals for no apparent reason. They became increasingly frequent until I couldn't start the computer at all. I thought it might be a hardware failure on the motherboard, but I couldn't be sure.

 

I have been trying to get either drive or the backups to boot in other computers but nothing works. With every drive (four in total) on the PCs I have tried so far (2), I get the same result: The computer boots, starts to load Windows, BSOD. The BSOD occurs when Class PNP appears on the command line. 

 

This being Windows, I can't read the BSOD message because it disappears too fast. There is no log because Windows never loads. How do you get around something like this?

 

What I really don't get is the fact that I see a BSOD with different disks on different computers. How can this be? I can understand a drive being damaged, but the backups were made long before any problems started. It doesn't make sense that they all have the identical error. The only thing I can think is it must be some kind of driver issue. Because the computer that these drives previously worked on is dead, I can't test with identical hardware. I don't know what to try next.

 

I can read the drives fine via USB. They just won't boot. I am happy to move on since it was time to upgrade anyway, but I need configuration data from the drives that I can only get when they are booted. Can anyone rescue me from this really horrible situation? The OS in question is Win 7.

Let us introduce you to windows HAL (hardware abstract layer)

 

You can't just put drives into other hardware platforms and expect em to work. Not without resetting SIDs or PnP detection phase to re-detect the platform changes

 

Less so on similar generation Intel platforms

 

More so on Intel Vs AMD (and graphics/southbridge chipset)

 

Likewise if you had dual boot and swapfile on different drives. Windows bootloader doesn't see "c" "d" etc. It sees disk(number) partition(number) Bootloader(type). That code can only be on 1 of the drives. While OS can be referenced on others.

 

It dies = no boot.

 

OS referenced on different drive to boot code dies = no boot

 

So what booted once, May not if a drive/partition goes offline. The task would be to fire up Hirens or similar and check all the partitions you expect are visible. And that the right windows folder is where it should be, along with view the boot options

Thanks for  the reply. I have to work with what I've got. Past experience is that wrong drivers cause errors, but never something like this. I really need a way to load Windows on another pc, even if some things don't work. I have done this successfully in the past. At the very least, I need to see what that damned error message says. Taking a picture is hopeless. Maybe a video. I don't know.

have you tried forcing safe mode to boot on minimal drivers?

 

 

 

as above, it sounds like you have got a classic case of incompatible drivers on boot.

I've tried everything I can think of, including every possible variation of safe mode. Nothing makes any difference.

What can you do? Lots. The potentials are endless. Even a bios update/reset can toggle SATA AHCI off and stop booting.

 

W7 recovery mode (you installed it and have media onhand right.. I always made a 2nd hidden recovery like W10 does for you now)

 

Hirens

 

F8 disable.

 

F8 Safemode

 

Both capable of offline loading registry and disabling BSoD auto reboot. or do it in F8

 

https://www.lifewire.com/disable-automatic-restart-advanced-boot-options-menu-windows-7-2624530

 

W7 recovery can interrogate any missing essential boot files

 

Both able to view HD if intact and read the bootlog

 

Not that a BSoD will likely help much. Unless the video drivers are doing it, in which case safemode will fix it in std VGA

I have had this in the past with ainciant HP machines where the bios was changed between LBA and large on the sata drive settings.

 

Also you will get bluescreens if you are trying to boot with AHCI and the install was done on legacy setting with older windows, Also if you are using onboard raid vs onboard sata vs PCIe chipset controllers for the sata connection.

 

You will probably be able to boot a USB installer for windows and do a repair. Its been some time since I have tried that since reinstalling is so much quicker now on current hardware than trying to get old installations working again.

I would create a W10 USB recovery drive on another PC with the same version of W10.

Then, after booting from the recovery drive, using CMD, try running through the following options:

As far as I can tell, Microsoft was the culprit(!). I started getting BSOD errors after a couple of Windows updates were installed (which is the reason I am wary of updates). Based on prior experience, I uninstalled the updates and the BSODs immediately stopped. But after a few days, I started getting them again, only the pattern was different. Then they started coming more and more frequently, until the computer became unusable. Now I can't get that machine to respond at all with any drive and the drives and earlier backups are all blue screening on every machine I have. I'm no technical wiz but I do know some things and I have built my own computers in the past. But I haven't got a clue what is going on here. I have never seen anything like it.

 

I didn't make any other changes to my set-up when the blue screens started. Windows update was the only thing.

If its booting ok, but not loading W10 because it's corrupted, you could try the DISM utility using CMD from recovery usb drive.

 

"Windows 10 includes a nifty command-line utility known as Deployment Image Servicing and Management (DISM). It has been around since Windows Vista SP1, and now comes installed by default on Windows 10 and Windows 8.1.

 

The utility can be used to repair and prepare Windows images, including the Windows Recovery Environment, Windows Setup, and Windows PE. Also, DISM can be used to fix the recovery image within an installation of the operating system and even to service a virtual hard disk".

addendum to above: For everyone's information, I am currently using an old legacy machine for test purposes. This is not a UEFI issue. It may become one later, but right now I am just trying everything I can to get the drives to boot at all.

This is also not a Win 10 issue. As stated in my original post, it is Win 7. I am going to upgrade to Win 10 on a UEFI machine, but I need to get these drives to boot first. Once I have the stuff I need, I will reinstall on the Win 10 machine.
