G62 notebook - recovering from unsuccessful attempt to upgrade to Windows 10

[Craig3428]

Hello. First let me tell you about my machine:

    HP  G62x-400 CTO Notebook

    Model # LD642AV

   [personal information removed]

    Windows 7 home premium

I attempted to upgrade ton Windows 10. At the very end of the process, I got an error message saying that the upgrade failed. I thought -- so I am back to Windows 7 and that is OK. But now, I receive frequent error messages telling me that various "entry points" can not be found on DLL files that I believe are in Windows 10 ONLY. How do I get rid of the problem?

Thank you for your help.

Hello;

Allow me to welcome you to the HP forums!

Wish I had good news for you, but I don't.

While Microsoft tells you that there is no risk in the Win10 Upgrade, because they let you believe that you can always revert back to your original OS and setup within 30 days, the ugly fact of the matter is that the Win10 GoBack function has proven to be unreliable -- and when it fails, it can leave machines in a corrupted state -- which doesn't always happen, but it does happen often enough to be a problem and you won't get any warning in advance that it is going to trash your PC!

So, while you DO have Win7 back, most likely, something got corrupted in the process.

To further complicate matters, while I would recommend using HP Recovery Media to restore your PC to its original condition. That would erase the entire drive, format the drive, and install the OS, the drivers, and the HP utilities.

Unfortunately, there is no HP Recovery Media linked to the HP Product Page for your PC. This could be an oversight by HP, or it could also mean that HP no longer stocks the recovery media for your PC. They no long stock recovery media for the older PCs.

Since HP no longer provides Recovery Media for your model, a couple of other sites you should check are: http://www.computersurgeons.com/ and http://www.restoredisks.com/

Understand that the first thing Recovery Media does is reformat the hard drive -- erasing everything from the drive. So, BEFORE you attempt this, you need to save off all the files and data you want to retain.

Good Luck

Thanks for the reply. My hard drive does have a D partition for recovery. I wanted to avoid that approach, but may have to do it.

The Recovery parition being present is not enough for the HP Recovery function to work -- as Win10 corrupts stuff INSIDE that partition, or changes the partition alignment -- not problems you are going to be able to see.

If F11 does not work, that's a sign of corruption.

Thanks for your guidance. This whole situation is too bad. shame on Microsoft for not doing a better job of undoing the mess they created.  I will try F11 and then get recovery media if F11 doesn't work. Of course, backup data etc before starting to fix this.
