Hi have a Acer A315-21-21A3
My windows 10 version has reached the end of service and trying to install version 20HA

Have tried using Windows 10 update assistant and also made burning iso to disc but always fails to install.

Now new message.

The installation failed in the SAFE_OS phase with and error during BOOT operation

Has anyone any ideas as most online don't work..

    Which version of Windows 10 are you running right now? Which AMD processor is installed in your system? I believe Microsoft dropped some support for older one at some point, so you'll want to install the latest supported version.

    You’re A315-21-21A3 came OEM with the Windows 10 Home 64-bit and it’s a known fact that 20H2 is a problem with these older AMD CPU’s. The solution and a common fix is to first update the BIOS of your A315-21-21A3 to the last update version 1.25 dated 2020/06/03 “Fix SMBIOS string issue” and then try again to install the last Win-10 update which is the Windows 10, version 21H1 update history and all its updates as there are 16 updates to this version of windows 10. Try that first and let us know if it works?
