    I do not take any responsibility if you brick your computer when flashing the BIOS.
    Proceed with caution.

    I used a Clevo W860CU for this. Your mileage may vary. It should work for all computers though.

    Ultimate Boot CD - Overview
    UBCD is a bootable cd with different tools for editing, dos antivirus, LLF and so on. Check the website for more information about the tools.

    Tutorials:Remastering - UBCDwiki
    Is used for reference.

    For information on how to flash and the different bios for clevo computers.

    It should be possible to create a bootable CD without UBCD.
    What you need is a SATA ODD driver that loads when booting.
    I have not found an easy way to implement it and that's why i used UBCD.


    Latest UBCD iso ( Ultimate Boot CD - Download the UBCD )
    The image file that will be used for booting.

    7-zip ( 7-Zip )
    For extracting the iso for editing.

    IMGBurn ( The Official ImgBurn Website )
    Burning the Iso.

    An empty cd/dvd for burning (Use quality media! Verbatim is highly recommended)
    Media used.

    OPTIONAL (but recommended so you don't waste cds/dvds):

    Virtualbox ( VirtualBox )
    This is used for trying out the ISO in virtualbox before burning to see if it boots correctly.


    in this guide i will create folders in D:\ where i stash the ubcd iso, extracted one and the new rebuilt one. It doesn't matter where you put it as long as it's easy to access.

    1a. Create a folder on your preferable partition named UBCD (in my case D:\UBCD).
    1b. Create a folder inside D:\UBCD called UBCDE (E for extract).
    1c. Create a folder inside D:\UBCD called UBCDC (C for custom iso).
    2. Download latest UBCD iso from the website and put it in D:\UBCD.
    3. Download and install 7-zip and IMGBurn.
    4. Start 7-zip and locate your UBCD iso in D:\UBCD.
    5. Hit extract and extract all the content to D:\UBCD\UBCDE.
    6a. Once done extracting you can now add your preferable Bios files.
    6b. Create a folder on D: called Clevo. Create folders under it with the different bios versions so you can remember which one is which.
    In my case i have three folders (yours may vary depending on how many bios updates you want to add). I've got W86_B14 W87_B12 W86_B11.
    7. Go into D:\UBCD\UBCDE\UBCD\Custom and add your clevo folder with all the different bios versions. Remember to create different folders for different Bios updates.
    8. When you are done adding and sorting up your different bios versions it's time to create the custom iso that will be used by burning.
    9. Open up Command with administrative rights (Windows key + R, type cmd and press enter under Windows 7 X64).
    10. Browse to D: by Typing D: in command prompt.
    11. Type: cd ubcd\ubcde\ubcd\tools\win32\ubcd2iso
    12. It's time to build the iso. Type ubcd2iso D:\UBCD\UBCDE D:\UBCD\UBCDC\UBCDC.iso
    Wait for it to finish.

    OPTIONAL (but recommended so you don't waste cds/dvds)

    You can now try your newly created iso inside virtualbox. I will not go into detail on how to use virtualbox since there's plenty of guides.
    In short, you create a new virtual machine (doesn't matter which one but i used win 7 for peace of mind).
    Go to settings, storage, click the empty below IDE, set slot to IDE Primary master, Open virtual media manager, Add, browse to your custom iso (D:\UBCD\UBCDC\) and select UBCDC.iso, Hit select, OK and then start your virtual machine.
    Boot the cd, start UBCD FreeDOS and choose setting 1.
    Once a window pops up, select Exit.
    Browse to your T: ( by typing T: ) and check if your clevo folder is there (type cd ubcd\custom\clevo).
    Type dir to see your bios folders.

    13. Start IMGBurn, select write image file to CD. At source, select "Browse for a file" and locate your iso (Which should be in D:\UBCD\UBCDC\ if you followed this guide.)
    14. Change Write Speed to something preferable (as low as possible). The image is only about 300mb so it wont take long.

    DONE! You should now have a bootable cd with your bios update files.
    But how do you use it? See below!

    15. Reboot your computer and change your boot order in bios to your DVD-rom as first in the boot order.
    16. Boot up the cd. Here you get a lot of options. UBCD contains a lot of good tools for different kind of tasks, like LLF and such.
    17. Select UBCD FreeDOS R1.38 (Based on NwDsk 3.40) And hit enter.
    18. Select the first option (i honestly don't know what the other is for, but first works fine).
    19a. Once it has loaded there should be a pop up with different settings;

    Launch UBCD Applications.

    19b (optional but helps if you are using a different keyboard layout).
    You can edit some settings by checking out Nwdsk (selecting and pressing enter).
    One setting that could be preferable to change is Install keyboard driver.
    Here you can change your language of your keyboard as it defaults to US layout.
    Select "install keyboard driver" and hit enter.
    Select Config.
    Select your preferable keyboard layout (Swedish for me), hit enter, select Save and hit enter.
    Once it's finished, hit ESC.

    20. Back to the menu you just select Exit and hit enter.
    21. Now it's time to browse for your clevo folder. type T: (this is your dvd-drive). Type "cd ubcd\custom\clevo" (without ""), type dir and you should be able to see all your bios folders that you added.

    And it's done! You should now be able to flash your laptop.

    Nice guide! Pretty helpful if you don't have an usb drive.

    Thanks. I wrote it up real quick while my memory was still fresh.

    While it isn't really cost effective to burn cd's (unless you have RW's) it never hurts to have a UBCD-disc. Can't begin to tell you how many hard drives i've revived using the different Low Level Format tools.
