    Reformatting a PC through USB device or LAN


    The system files in the hard drive got corrupted and the OS won't boot past the "starting windows" screen.

    So I decided to reformat the PC, however, it seems that the motherboard does not support USB boot.

    How do I do this? I have an option for network boot but as far as I know I need a server for that, I only have a laptop available.

    Is it possible to force it to boot via USB drive or do some 'magic' on my laptop so it can boot from the LAN network?

    Hello Notme,

    If you have secure boot and it's enabled, then you will not be able to boot from a USB flash drive until you temporarily disable secure boot in your UEFI firmware settings.

    Secure Boot - Enable or Disable in UEFI

    Hope this helps,

    thanks for the reply Brink

    the motherboard is about 4 years old, and the bios menu does not seem to have any option related to secure boot.

    BTW other additional hardware issues popped out, as I was about to try and find some useful options in the bios, the computer turns on but does not display anything.

    plugging the monitor via onboard vga port does not solve the display issue either. The monitor only displays continuous blinking power light

    sry for my bad english.

    Power off, and double check all of your connections (ex: RAM, graphics card, SATA cables, power cables, etc...) on the motherboard to make sure that they are fully, correctly, and securely connected.

    yep I did those already and still the issue persists.

    I'm guessing it could be that the BIOS is failing, the motherboard or the power supply.

    I also tried clearing the CMOS setting by disconnecting the battery and by the pin thing on the motherboard (forgot what it's called)

    also I tried to disconnect everything (video card, HD, RAM) and turning on the pc but still it displays nothing.

    The minimum required for a PC to post is power supply, motherboard, CPU with heat sink, one stick of RAM, video card and keyboard. If the motherboard has onboard video then an add in video card is not needed. Unplug everything else including hard drives and optical drives. Double check all power cables to make sure they are plugged in tightly and reseat your RAM module. If it will post now, power down and add components back in one at a time until it fails to post. When it fails again its likely that last component you added "or" your power supply got overloaded. A weak or failing power supply can fool you into thinking its something else like a video card. I would have a good look at the motherboard and check for any bulged or leaking capacitors. If you see goop on one its probably failed.

    I've had one or two PC's that were tricky to boot from a USB thumb drive. On one I have to select USB Hard Drive as the first boot option. I also had to go into the section where the hard drives were listed and move the listing for the thumb drive to the top. This had to be done with the thumb drive plugged in. Then on the first reboot during the Windows install I had to go back in a swith it back to the default hard drive. Also, I haven't had to disable secure boot on my laptop to boot from a Windows 8.x install thumb drive. I would think you would have to disable it for Windows 7 or Linux but 8.x should be fine.

    Thank you alphanumeric for your insights. I tried your suggestion and nothing still works.

    I just opened up the power supply to look for fossils, err, something that might be off (it's pretty dusty)

    but I guess it's fine.

    the motherboard does not show any signs of bulging/leaking capacitors.

    later I'm gonna try swapping the power supply and see if it works.

    but I remember this same thing happening on the PC we had before,

    days later the video card began shooting off fireworks.

    on the boot up process by USB, you mean I have to go to boot options and see if the usb device is detected?

    last time the options for boot only included my HD and the network drive

    btw the model of the motherboard is H55MXV

    Be careful with opening that PSU. It can still electrocute you even if unplugged.

    ya it gave me a little shock when i was picking the build up dust.

    still won't show display. there are no beeps too. Now I wonder if it's just the CMOS battery that's causing the issue.

    The thread seem to branch from my main concern, can I change the thread title so maybe if someone with the same problem some guy with a solution won't go past?
