    cannot boot usb flash iso


    Last week the power supply on my monitor died; when i plugged in the replacement and booted up, the startup failed with pfn list corrupted message - one I have seen before and fixed with TEN FORUMS help tracing it to driver problems. The previous time we updated all drivers and disabled an obsolete tv card. I suspect somehow these fixes have gone wrong again but first I want to upload my data for you guys to have a look. I manually configured a bootable usb flash with latest iso (per the tutorial); splitting the install.wfm {?} file to be fat32 compatible. The flash drive wouldn't boot after setting it up UEFI in bios, so it started the purple install program. The PC can read the drive (looking at files in command prompt from the troubleshoot menu). SO, I can't run the log collector v2 from the command prompt and I cant boot the ISO USB to start repair upgrade. I did not state my windows version because I cant read it, but it was the latest update to w10 home. HELP!

    :)

    Bootable USB with ISO - What am I missing?

    Have you copied all the files from the ISO to the flash drive? I can't see that step.


    After step 10. (after formatting and making it the active partition)

    Copy files from the ISO to flash drive.

    Open CMD as administrator.

    navigate to the flash drive, lets call it drive Z and type in the following commands.
    Z:
    cd boot
    bootsect.exe /nt60 z:
    exit


    Then try again.

    Bootable USB with ISO - What am I missing?

    I am trying to install win7 from a USB. I set the USB to be first boot and it finds it, but wont install the iso.

    I have tried ...

    However when I get to bootsect it does not do anything .. says it is not a recognized internal command ...

    Is there something I am missing? I even tried just loading the iso on the USB and booting, but did not work either

    Is there an easier way?

    Bootable USB with ISO - What am I missing?

    Tried the first program, but it fails .. not sure yet why but troubleshooting that ...

    The pendrive seems to be only for linux? although seems very useful i dont think it will help me with this. Keeping it for future linux installs though

    hmmm if I already have the iso, do I just throw that in the usb drive?


    ok looking into this as well...
