    USB Boot Issues on Acer Aspire S7-392 UEFI, GPT, etc.


    I recently purchased an Acer Aspire S7-392 that came pre-loaded with windows 8. While I was attempting to make the machine dual-boot (with Ubuntu), I wiped out the original Windows 8 install.

    I purchased a recovery USB from Acer. This USB stick boots fine and the Windows 8 install goes smoothly until, when it is finally finished, and it says that the version of Windows that I have now installed is inactive and must be activated with a Microsoft Product Key. Acer won't do anything about it and wants me to return the machine to them to be repaired. They claim that the embedded product key on the hard drive has somehow been corrupted and it must be sent back to them to be fixed.

    I really don't want to have to send the machine away.

    My employer (a university) has access and licenses to all microsoft products. So I thought that I'd try to install windows 8 from a different source. I have a Windows 8 Enterprise 64-bit DVD that I have made into a bootable USB with Rufus (I originally tried the Windows DVD-USB utility but it formats the USB as ntfs which I have read is not going to work under UEFI machines - in any case, I tried it and it wouldn't boot either).

    Now, for the life of me, I cannot get the machine to boot off of the USB stick. I have tried in UEFI and legacy mode, with secure boot on and off, and with the sata mode in Raid and AHCI mode.

    According to Rufus, the USB drive from Acer (that the machine will actually boot from) is flagged as non-bootable. Out of desperation, I tried to format my other Win 8 USB this way - to look more like the USB stick that works, but that didn't seem to help.

    I found another thread: http://Need more help with Win 8 & 7...ot (UEFI, GPT) here in the forum that describes a situation pretty similar to what I'm seeing.

    Last week, I was able to get a USB stick with Ubuntu to boot when I killed the Raid setup via the Intel Rapid Store configuration. With no raid and the bios in legacy mode, I was able to install Ubuntu. However, I would really like to get Windows 8 restored to this computer.

    I have upgraded the bios from V2.03 to V2.05 (the latest from acer). I have tried to run confirm-SecureBootUEFI in an elevated command prompt terminal but windows says that it cannot find the command.

    From what I've read, people are having trouble with these Acer machines. Does anyone have any suggestions (short of abandoning the machine and going with something else)? Is there something in the bootable USB recipe that I'm missing? Any other ideas?

    I would love to activate it, but since it was a machine with pre-installed windows, there is not an activation code. The enterprise version of windows 8 that I have is also a volume licensing situation, so there just isn't a standard Microsoft access key available. Likewise, the Acer recovery USB doesn't have an access key.

    I have not tried to activate windows online.

    I do not have a product key with which to activate.

    A product key is a 25-digit number that's used to activate Windows 8/8.1. Activation helps verify that Windows hasn't been used on more PCs than the Microsoft Software License Terms allow.

    Your product key should be in the box that the Windows DVD came in, or in an email that shows that you bought Windows.

    It looks like this: PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

    In all cases, the installation was attempted with the computer connected to the internet. The UEFI/bios-embedded product key is apparently not functioning - this is why Acer wants me to send the product back for repair.
