    Installation media boots to command prompt

    I've just booted from known working install media to see exactly what it does when booting. The sequence of events is...

    1. Windows logo on a black screen
    2. circling dots appear beneath the logo
    3. light blue 'Please wait' screen with circling dots
    4. a command prompt window (very briefly)
    5. the initial Setup page appears

    Do you see steps 1-3? If so, it appears you have stopped at step 4, suggesting that something on the disc cannot be read.

    Does the disc boot properly in another machine? If so, try cleaning the laptop's drive lens then try booting from the disc again.

    If not, make new install media with Microsoft's Media Creation Tool, either as a bootable USB, on an ISO that you can burn to another disc. At Step 8 in Option One of this tutorial you can choose between making a USB or an ISO.

  3. Installation media boots to command prompt

    I do not believe its a keyboard malfunction because same thing happens with usb keyboard. Is that what you mean by external? I tried installing using an external optical drive also but get the same results.

    I created a windows 10 x64 installer via microsoft media creation tool. I have used 2 different drives that i know be in working order. I also created a dvd installer via media creation tool as well..
    When i boot to the DVD i see the circles. i didnt notice windows logo but above the circles had the HP logo. before that i get the boot to cd/dvd option.

    When installing via the usb installer since i have both x32 and x64 on it i choose the x64 option and then i see the spinning circles but boots to command prompt after that. i dont see anything before that.

    I know all my installers are good. I even tried to boot to an official windows 8.1 disc and the same thing happens..


    I have reset bios to default. I made sure the secure boot is turned on. I guess i could try turning it off to allow legacy but i know for a fact i do not need to do that with these installers. but i could try. any other thoughts?

    Why X lines appear when booting from a Bootable Installation Media?

    Multi-bootable USB

    Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

    I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

    The list of bootable images i'm trying to create are

    1. Windows 10 (A full OS running from thumb drive)
    2. Windows 10 ISO (Bootable disk image for fresh install)
    3. MemTest86+

    Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!
