  1. I cannot boot my c drive after flashing my bios


    Hi, I currently have Windows 10 pro on my PC. I installed a new bios today so I could get secure boot in preparation for Windows 11 pro. When I start my PC the system does not recognise the c drive anymore. I cannot get into my PC. I didn't anticipate this happening so I didn't create a recovery disc. Any ideas? Kind Regards Mr Song

    :)

    If you have been suffering messages such as 'Adapter not Found' , 'ERROR 0FL01' , 'Invalid Adapter or BIOS Selected' when trying to flash or reflash your Video cards Bios and you are lucky enough to own a PC capable of running more than one PCI-E Video card then this could just be the Guide you've been looking for.

    ------
    Part 1
    ------
    Step 1 Create USB Boot Drive with HP USB Disk Storage Format Tool

    Step 2 Copy all the USB Boot files to the USB Boot Drive (do not overwrite files when prompted)

    Step 3 Copy ATIFlash files USB Boot Drive

    Step 4 Copy new BIOS file to USB BOOT Drive (name it something like bios.bin as you will be using this name in a DOS Prompt later on)
    ------
    Part 2
    ------
    Step 1 Boot into 'Safe Mode' (by pressing f8 before booting into Windows)

    Step 2 Uninstall ATI Drivers and Associated Software then Reboot
    \
    Step 3 Go to Device Manager 'Display Adapters' and Uninstall (including Software when prompted)

    Step 4 SHUT DOWN your PC (DO NOT REBOOT, if you should so happen to Reboot repeat Step 3 above)
    ------
    Part 3
    ------
    Step 1 Remove your Video Card from the top PCI-E slot and place it in a different PCI-E slot (this is the step that sets this Guide apart from all the others)

    Step 2 Reboot into your Mobo's Bios

    Step 3 Once in your Mobo's Bios change the first Boot Device to USB-HDD (or your Equivalent setting) then Reboot

    Step 4 At the C:\ Prompt type, atiflash -ai 0 ,this will provide you with proof that your Video Card does infact exist

    Step 5 At the C:\ Prompt type, atiflash -unlockrom 0 , i suggest you do this because some Bios files are infact locked and can't be flashed until unlocked

    Step 6 At the C:\ Prompt type, atiflash -f -p 0 bios.rom , this is when your Bios is actually flashed

    Step 7 Once your Bios has been flashed simply 'Ctrl+Alt+Delete' to restart your PC

    Step 8 Go straight back into your Mobo's Bios and change your first Boot Device back to what it was (probably HDD) then Reboot for the final time and your finished

    I cannot boot my c drive after flashing my bios

    install.wim is 7GB, how to make a bootable USB flash drive

    This is a method to make a ntfs flash drive.

    The trial and error step will be booting using Legacy BIOS...

    Code:
    This is the link:
    Guide: How to Format USB Flash Drive Using Cmd - EaseUS

    The link did not use active so that is why it is a trial and error step.
