    I asked you whether you're booting the installer as UEFI device or if any show up. Please do not skip any further questions or steps if you want my help. I have dozens of cases at all times and don't need to be repeating steps which are ignored, which often contain the solution. This requires utter thoroughness or take it to a shop

    It's not possible there are no UEFI related settings in a UEFI BIOS. Make sure you have the latest BIOS/UEFI firmware from PC or mobo Support Downloads webpage. Check again on all tabs for the settings I requested.

    Why no description of the failure. We need exact description and pictures of this and BIOS choices if possible. Attach files using paper clip icon.

    My sincere apologies if I am being vague, I really appreciate your help Greg and indeed everyone else's. :)


    The only UEFI setting that I can see listed in the BIOS can be seen in the first pic below.


    Yes, I am booting the installer as a UEFI device. The error message that I am getting can be seen in the second pic.

    Let us see Boot and Advanced tabs settings. There should be CSM, Legacy, possibly Secure Bbot.

    What about the BIOS update? While checking the Acer Support Downloads webpage look for model's Manual to consult.

    Was this the first reinstall? We're any changes made in BIOS at all?

    Have you tried a Legacy install or is there even a choice to Boot the installer that's not EFI?

    Here is shots of Boot (first pic) and Advanced (second pic). There is no SSM, Legacy or Secure Boot options.

    The bios is updated to the latest verison 209.

    This is the first time I've ever reinstalled on this machine.

    Yes there is an option to boot to the installer that's not UEFI but when I select that option I just get a flashing '_' and nothing else happens.



    Just to clarify exactly what I have done so far -

    Firstly I made a bootable Windows 7 USB Flash Drive using the Windows 7 USB-DVD Download Tool.

    I booted this up selecting the USB (without UEFI) boot option and once I got into the 'Where do you want to install Windows?' screen, I deleted the partition which was the original factory installed Windows 7 partition. I did not touch the other factory installed partitions. I then selected this partition to install Windows 7 onto and it installed no problem.

    The machine then loaded into Windows 7 and I went to explorer and noticed that the other partition was not showing and I panicked because I had backed up files to one of those partitions.

    I was told to assign a drive letter to the partition where the files were backed up and was able to backup to an external drive. Phew! :)

    So then in my wisdom I decided that I'd reinstall using UEFI.

    I followed OPTION 1 in the 'UEFI Bootable USB Flash Drive - Create in Windows'.

    I then followed the How to Install Windows 7 Using the "Unified Extensible Firmware Interface" (UEFI).

    I click 'Next' to install and then I get the BSOD.

    The image in post# 374 shows Disk1 as removable 3.73 GB - NTFS - is this the USB install media?

    That will not work for a UEFI install.

    Could you post a new disk management screen shot with the USB drive connected?
    Please make sure that members can see all pertinent information
    See: Disk Management - Post a Screen Capture Image

    You might have to post more than one screen shots since you're using a camera.

    I still think you'd have more success if you create the install media on a DVD - at least that would eliminate one possible cause (USB formatted with the wrong file system)
    You CAN use the Windows 7 DVD/USB download tool to create a UEFI DVD install media using the same ISO file you used to create the USB (you CANNOT use the tool to create a UEFI USB install media!)

    Anyway, post the new disk management screen shots and then we'll see what needs to be done.

    Eureka! I changed to a 16GB USB pen and booted up without UEFI and it's installing as I type!

    The 4GB USB Pen was the problem. Brilliant stuff! Thanks so much for that little bit of help Bill!

    You're welcome.

    The credit belongs to Greg as he was trying to help you install without UEFI. I'm not sure exactly how I helped other than perhaps pointing out the file system issue with the Windows 7 DVD/USB download tool and UEFI install.

    Could you elaborate on changing to the 16 GB USB pen drive?

    Did you use Rufus?
    What options did you select when creating the install USB?
    • Partition scheme:
      1. MBR partition scheme for BIOS or UEFI computer
      2. MBR partition scheme for UEFI computer
      3. GPT partition scheme for UEFI computer


    • File system:
      1. FAT32
      2. NTFS

    This might help other people who experience similar difficulties.

    The tutorial specifies GPT partition scheme for UEFI computer, but I believe MBR partition scheme for BIOS or UEFI computer is the better option when creating USB install media with FAT32 file system regardless of UEFI.

    Please post again after the install is complete and let members know how your system is performing.

    Just a note on the screenshot image in post #374 that shows Disk1 as removable 3.73 GB - NTFS.
    I took that screenshot after the first reinstall. That was created using the Windows 7 USB-DVD Download Tool. Hence the NTFS file system.

    Yes I used Rufus.

    I used GPT partition scheme for UEFI computer and the file system I used was FAT32.

    This is the exact same process that I did on the 4GB USB pen drive that would not install.

    The reason I changed to a 16GB pen drive was because I mis-read what you said in post #384. I thought it was the size of the USB Pen drive that was the issue (4GB too small) so I got a larger one. When in fact you said it was the NTFS file system that was the problem. Doh!

    All is well anyway and maybe a larger size USB Pen drive is needed or maybe it was just the change of USB Pen drive that did the trick.

    Many thanks to Greg too and again I'm sorry if I was frustrating with some of my replies, it really was totally confusing me. :)

    I'll run all updates etc and report back with how I'm getting on.

    That's the magic of the universe - answers are provided ... sometimes in a round-about way.

    Good job 'figuring' out that I meant use a different flash drive

    Seriously - good thinking on using a different device. DVD install media would have gotten you past the issue too, but then you'd never know about the 4GB pen/thumb/flash drive.

    The 4GB pen drive should not be trusted, IMO. It might be on it's last legs and data could be lost. Trash that suspect drive and get a new one if you need it - they're cheap enough now.

    You can test the drive PW surface scan to find out for sure. Then zero and reformat.

    Wasn't the issue that you hadn't yet formatted stick for UEFI as shown in screenshot detailing NTFS instead of FAT32?
