Black screen before Windows logo

I recently restored a disk image made from an HP Envy 17t-K200 to an HP Envy 17 K250CA notebook, which has an identical motherboard.  There are now two operating systems on the K250CA.  One of them, a fresh Windows 7 Professional SP-1 install, works fine.  The other -- the restored disc image -- boots a black screen, without the Windows logo.  If I use the Windows installation media to repair startup, it reports that the O.S. booted successfully.  There is no hardware issue, because the other O.S. performs normally.  I'd appreciate suggestions on getting the restored O.S. to work.   I understand there are some driver issues, but I don't see how that would stop the  Windows logo from appearing.

Hi ddantes,

I understand there are some driver issues, but I don't see how that would stop the  Windows logo from appearing.
Actually, if there are graphics driver issues, that could be a cause for this behavior. I'd suggest updating (or reinstalling) the graphics driver with the latest version from the HP website.

If I use the Windows installation media to repair startup, it reports that the O.S. booted successfully.
I would try a non-destructive repair of Windows. There is an excellent tutorial with step by instructions on how to do a non-destructive repair of Windows 7 in this Non-destructive reinstall of Windows Vista and 7 article on the WinHelp.Us website. I'd give that a try if refreshing the graphics drivers doesn't work.

I hope that's helpful.

Regards, Andrew

Thank you for your suggestions.  However, it may be challenging to implement them.  Installing a graphics driver, or performing a non-destructive repair of Windows both seem to require that the affected operating system be loaded and operational.  If the screen is black, I'm not sure how I could take either of those steps.  Please advise.

My apologies, I misread your initial question to mean that the operating system was otherwise performing correctly, but re-reading it now, I see it was the other operating system that is performing correctly. My mistake.

Can you clarify what software you used to image the problematic operating system and did it have the option to include drivers for the new computer on restoring? Also, are you still able to re-image that system or has it been wiped already?

Both operating systems are Windows 7 Professional SP-1.  The disk image was made with O&O DiskImage.  There is an option to cause Windows Setup to launch when the defective O.S. is loaded.  I just discovered that option, and am about to try it...

After the supposed "Machine-Independent Restoration", the restored operating system still has a black screen.  Supposedly, the HAL was exchanged with the functioning O.S., and required drivers were identified and restored.  The Windows Setup was supposed to launch when the restored O.S. was booted, but it did not.  I've notified the software vendor and asked for their input.

Good move. That would have been my next suggestion :)

does the old system still work? then compare the BIOS settings of both systems
probably it is set to the wrong boot priority

Can you get safe mode to load? It should have a generic video driver running... If you do, maybe you can get the proper video driver going...

Thanks to all Experts.  There were no differences in BIOS settings, and there was a black screen in Safe Mode as well.  I abandoned this approach, and am going to try ZInstall instead of using a disk image from the other computer.

what is ZInstall?

ddantesAuthor Commented:
It's an application which claims it will transfer all programs, files and settings between computers with different hardware, as long as the operating systems are congruent.   I have yet to test it.

I was pleasantly surprised by the results with ZInstall WInWin.  Most of the applications and settings were successfully transferred.  I'm not sure I've discovered all of the remaining issues, but some programs needed to be reinstalled, and some settings were missing.  For example, the Quick Launch toolbar was not enabled or populated.  Ctrl+Alt+Del did not work, but SFC /scannow fixed that.  All in all, it was a success.

I'm posting again, because the cause and resolution of the issue has become known.  I had changed the notebook's  BIOS settings, in order to be able to boot from a legacy CD/DVD drive.  Having done that, the system disc became un-bootable until it was changed from GPT to MBR.  Once that was done, Windows 7 loaded normally.

Understood.  My apologies for that, and I hope if they are interested, they will keep reading until they see my comment about GPT vs MBR.
