Windows 7: Flashing bios through flash drive

Any replies will be appreciated and i will give +rep

It looks like you download a .rar zipped file sk16v210.exe, then execute that file to expand it to see 2 programs: a Windows based installer and a Diskette based installer.

Toshiba assumes you will put the Diskette based installer (most likely an .exe file) on a floppy or CD and boot to that drive. I would assume the update program will start from there.

I don't see why the same thing can't be done on a USB stick, provided you have the option to boot the USB drive first in the boot order, or by a BIOS boot menu option.

Does that help?

Hi yugzyugz,

Extract the contents of the downloaded Bios Zip file into a folder.

Run the launcher.exe. You have only two options. 1.CD-ROM installation and 2. Install from Windows. Install from Windows as indicated in the instructions itself, is riskier than installing from the CD-ROM.



Load a blank CD-RW into your optical drive, select the Radio button "CD-ROM Installation" and click on OK.

This will bring the native Windows Disk Image Burner ready to burn the bootable ISO sk16v210.iso. Check "Verify Disk after burning" and click on "Burn"

"Once you create the bootable CD-ROM, simply boot your computer from the
resulting CD. To boot from CD, you can either hold down the "C" key while
you turn your computer on, or you can use HWSetup to change the boot priority
so the CD drive boots before the HDD."

Now it should be possible to create bootable flash drive with the same bootable ISO sk16v210.iso. ( In fact I created one using RUFUS -Rufus - Create bootable USB drives )

However as a matter of abundant caution - not very sure how the pendrive image will unfold - I would prefer to stick to the manufacturer's instruction to the dot and run the bios flashing from the CDROM drive.

( It is a different story if it were an executable DOS file. Then without hesitation I would have made a bootable DOS pendrive, moved the executable DOS file into the pendrive, and run it under DOS.)

NOTE: Read all the instructions in the Readme file. Ensure that there is no interruption during the flashing process.

Thanks for answering it help me a lot now i've understand everything

Thanks a lot you deserve a rep

Great to see your problem is fixed. If you can mark your topic has solved .

I had a Toshiba Satellite lappy for a long while and I always updated the BIOS from within the OS (that option is provided) without any problems.
Hope it helps.
Cheers,
