    Acer E1 (UEFI) Auto repair bootloop...No usb boot


    Hi guys...I have an Acer E1 which started to bootloop. It would try to load OS(W8.1) but then the blue sad face pc crash screen pops up and then it try to load Auto Repair but all i get is a black screen...I have no USB restore setup (no optical drive on machine) so i decided to try a clean install...ive tried all the steps i found on this forum (deactivate secure boot, putting usb to boot first, F12 to choose usb boot, Rufus Usb Boot creator with a ISO i downloaded from windows media creator, Win7 Boot media creator, FAT32 format usb drive, bootsec.exe for 32 bit usb creation and many others). The wall im hitting is not that the bios doesnt detect the USB sometimes it detects it some times it doesnt(comes out as PNY Usb next to Usb hdd) but even when i set the bios to load the usb first it just doesnt run whatever is on the usb... I even use f12 to boot the usb and even when its detected it wont run whats on it. I even loaded the update for legacy bios and it would detect the usb but not load it. I dont know what else to try.

    TLDR; machine detects Usb drive in bios but doesnt boot whats on it even when set to do so or chosen.

    Affected PC: Acer E1 510
    Tools:PNY 32gb thumbdrive

    Verify you have secureboot disabled..
    Download and create windows 8.1 media (link in sig below)
    Download the x64 version if your system is UEFI with GPT partitions

    I did previously disable secure boot and still no usb boot,and i made sure that the Rufus application created a readable Usb by choosing FAT32 and GPT partitions. I will still try the links you posted in the sig.

    Another thing I forgot to mention is that the PC im using to create the USB is an old Compaq running Win7 32 bit. Could this be affecting the boot process also?

    Thank you!!

    That is causing your problem.. No need for Rufus and certainly no need for any partitions

    The - download and create windows media - tool will create its own bootable media - either USB or DVD

    Ok I will try that...I used that media creation tool beforehand to download the WIN8.1 X64 ISO but i used Rufus and also tried Win7USB/DVD tool to create the bootable USB. The problem is that my Internet is acting weird this last week and my download speeds are very erratic. I tried several times to just create the USB with the media creation tool but it wouldnt finish. The only one that seemed to work was the download ISO option...albeit after 9 hours and jumping from 23 mins left to 24 hours left every minute. Ill try it out and let you know. Thanks.

    No Luck...I was finally able to create the USB. I used a friends New Toshiba Win8.1 64bit laptop. Downloaded Media Creation Tool. Create Usb. Win8.1 64 bit. Finished. Turned on My Acer. Loaded Bios. Turned off Secure Boot. Put Usb in first boot order and enabled F12 to choose boot. Saved and restarted. Before restart inserted usb into 2.0 port. Acer splash comes on. 20 seconds pass. Little loading circles appear. 1 min passes. Black screen then blue screen Error. Restarts. Automatic repair hangs. . I shut it down. Tried f12 and it detects the thumb drive (says usb hdd: pny 2.0 usb) choose it. Same story. what else should i try?

    thumb drive (says usb hdd: pny 2.0 usb) choose it
    It appears you are selecting legacy boot device

    You should also see that listed a UEFI: pny 2.0 usb

    This is what F12 boot option sees:


    And this is what the Bios boot order sees:
