Can't upgrade from win7 to windows 10 on Probook 455 G3

[quarky99]

I have tried all remedies posted in the last 2 years to upgrade my probook from windows 7 to windows 10. I have used both the HP Windows 10 DVD that shipped with my probook, as well as creating a  USB Media Creation Tool. In all cases the upgrade DVD or USB stick require that the upgrade to preserve apps must be run from setup with Windows 7 running. I have visited HP driver support and updated drivers suggested, and removed drive encription as well as update bios. The upgrade always stalls at about 27%.. There  is some indication on the web that my UEFI bios may still be the problem. Can someone suggest bios settings that  can permit upgrade to succeed.. I  would like to try a legacy bios install but I don't know if checking legacy install is the only option to set for that mode.

To preserve existing settings, data, and apps, the Win10 Upgrade MUST be run from inside Windows 7.  If you run it outside, as would happen if you booted from Win10 media, that would force a clean install and you would lose everything in the process.

The Windows upgrade is a series of discrete steps, which tend to separate around the following percentage completion points: 30%, 75%, 100%.  So, if it is constantly failing just short of the 30%, my guess is that there are filesystem problems on the hard drive.

Switching to Legacy mode will not fix this, as that has nothing to do with the update crashing where it does.

All I can suggest is checking the hard drive for errors.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu -- that will look similar to the image below ...

3) press the Function key for testing the hard drive (usually F2) and let it run.

Please report back the test results.

I used the UEFI bios to run the four available hard drive tests.

All tests passed.
