Old computer if from Windows7 upgrade to WINDOWS10 constantly restart into the system, or want to use WINDOWS10, how to do?

Let's talk about my configuration: 08 Acer Aspire 5520g, very old computer, in addition to the memory added to 4g, the other is unchanged. Official support only to windows7, and official note that the model is not officially supported by the WINDOWS10 list.

Before Windows7 on the launch of WINDOWS10 upgrade assistant, I first time appointment, assistant display can upgrade (without any upgrade problem), was also happy for half a day.

When the July 29 Windows10 was released, I upgraded the first time ( How does the Windows upgrade work immediately without waiting for Microsoft to push in batches?). ).

But the cup is, after the upgrade, the system boot just see the New Start icon, the system immediately restarted, has been circulating, and then no way can only back to Windows7, first share the next step back (step and " infinite Restart, roll back WIN7 Success, recovery method "consistent, citing from the Security Community of the safe ):

① in the WIN10 Blue window logo under the white circle in the turn, a few 5 seconds, and then forcibly press the power button until the notebook shut down.
② Restart the computer, repeat the previous step 2-3 times until the recovery screen appears.

③ mouse click on "View Advanced Repair Options", click "Troubleshooting", click "Advanced Options", click "Fallback to previous version"

Note: The middle may appear: Select the user name you want to use to recover, enter the password for that user name, and if not, enter directly. May appear to ask you to enter the key, no effect no, click ignore the drive.

④. Finally, click "Fallback to previous version" to begin returning to the pre-upgrade operating system.

⑤. If the card is in this interface for more than 20 minutes. Forcibly shuts down, restarts the computer, opens the opportunity to resume, waits patiently

⑤ after restore, if the WIN10 Blue Prompt window can not be installed, close the window, the black screen wait a few minutes.

Later looked at the following situation, as if the Win7 under some driving and win10 fight caused by.
