    I have an Acer Aspire E-15, an older laptop, that recently was knocked off line by a power surge. I had Windows 7 on it at the time. My OS was completely knocked off my computer. I still have the original CD that came with the PC but when I put the CD in and change the boot order to CD in the BIOS, then reboot, the error I get is no OS. I thought I could boot from the CD but that didn't work. I also have a small USB drive with Windows OS on it but apparently it is not boot-able because when I try to use it to boot I get the error, insert boot-able media. Is there any way I can get my PC running? Thanks.

    You might have to get back into the BIOS and Disable Secure Boot. While in there, Enable Legacy Mode (Disables UEFI Mode).
    Those are probably in some Security settings.

    I turned on Google again and set it as default. Now I am BGBG again. I had no real problems with it before but the Firefox login IS IN FACT DIFFERENT. If need be, I can always set FF ESR as default again. Unsure just what to do. Never had to have anyone tell me or do it for me before but I can say having different browsers is very confusing. I think I am in the wrong thread right now.

    OK done. But when I reboot I get "No boot-able device--insert a boot-able device and pres any key.
    That is my problem, my USB is not bootable and i can't get into Windows and use Rufus to make it bootable.The OS is just gone. Should I put BIOS setting back where they were?

    Back to Dave's issue: It's still showing that the computer doesn't see a bootable drive.
    When you were in the BIOS, you did change the boot order to go to the USB drive or alternately the CD drive first?

    Even if you haven't changed the boot order, you can choose to boot from a selected drive temporarily. On an Acer, I think you press the F12 button to get a menu that asks which device you want to boot from this one time. See if you can get that menu.

    Also, can you verify your USB drive is bootable or even readable using another computer?
    Same with your CD. Can you read it on another computer?

    Yes, I did change the boot order to USB/CD.
    The F-12 button led me to the same error:No bootable device--insert boot disk and press any key.
    My other Computer is a Linux desktop. Yes, I can read the USB on Linux. Whether it is bootable or not i cannot tell on Linux. I don't want to try to boot from it on Linux as I don't want Windows on my desktop. I am sure it is not bootable as I never used Rufus on it to burn the OS. Now, I can't use Rufus on it since I don't have Windows.
    The power surge may have just been a coincidence but it happened just before I lost the OS. I only assumed it was the cause but maybe it was not. Thanks.

    FYI....I took out my main drive and looked at it on my Linux computer. It appears to be readable, mountable and here are is contents if this helps:
    /media/dave/aad4a4e9-2662-42b9-98fe-316b4a302767/boot
    /media/dave/aad4a4e9-2662-42b9-98fe-316b4a302767/etc
    /media/dave/aad4a4e9-2662-42b9-98fe-316b4a302767/media
    /media/dave/aad4a4e9-2662-42b9-98fe-316b4a302767/swapfile

    Update, I replaced my main drive with one out of another Acer machine that has Windows already on it. Now when I boot up I get a blue screen with the error; Windows cannot be booted because a file is missing. Windows system 32 winload.efi you will need to use recovery tools. Error oxc000000.0f
    I have no recovery tools.

    When you used the F12 key, did you get the one-time boot menu?

    A drive with a working version of Windows would have a many more folders on it, including Windows, Program Files, Users. There should also be Windows files.

    It's my understanding that the F12 key on Acer Aspire is disabled by default.
    You have to access the BIOS first and enable it.

    I enabled E12 in the bios. When I pressed enter, I was taken back to the same blue recovery screen.

    When you pressed the F12, you should have been presented with a screen listing available ports to boot from, i.e. internal drive, CD-ROM, USB, etc.
    1) I'll assume you received that 'one-time -boot' screen and selected to boot from either the CD or the USB drive. Which ever device you chose, doesn't have the appropriate files on it.
    2) If you didn't get the 'one-time-boot' screen, the computer is still trying to boot from the internal drive.
