    Has anyone hit this with Windows 10, does this solution work the same? My wife has just advised that this has happened to our Aspire S7. Hoping it corrects itself without having to do this, as I've already had to do a factory reset since moving to Windows 10!

    Hello to everybody,

     

    I just happen to have the same error message and followed all steps indicated in this thread. However once my computer (Aspire Switch 11) has uploaded the BIOS file and restarts I get the following message: InsydeH20 - Secure Flash, Error: invalid firmware image!!!. I have checked and rechecked that I have the correct BIOS file dwonloaded from ACER support.

     

    Any ideas?

     

    Thanks in advance!
