Trouble creating Toshiba BIOS disc

Basically title says it all. I'm running windows 10 on an old Toshiba Satellite A665 from 2010, and noticed the battery quit charging and seems to be stuck in the "4 minutes until fully charged" basically battery stopped charging, and through my research its apparently a bios issue. So I'm trying to install updated BIOS from Toshiba's utility and it wont download from windows, so I went the "create CD rom option" so every time I try and burn the Disk file image over to an empty CD-R, I keep getting invalid DISK. So help me out here. What am I doing wrong? Long story short I'm trying to create a boot disc to update my laptops BIOS.

Use Rufus to make a usb if you need to https://rufus.akeo.ie/ That is if the laptop supports USB booting.

You can also find a generic boot disk at http://www.bootdisk.com/

So... don't use the Toshiba utility to download it? Use a web browser?

This BIOS is applicable to the following models:

  o Satellite A660/A665 models having part numbers beginning with "PSAW0U"
  o Satellite A660/A665 models having part numbers beginning with "PSAW3U"

That .exe is an archive that contains a file called "saw0v230.iso" That iso is already bootable, just burn it to a disk using CDBurnerXP or similar software and boot from it.

If the opitcal disc drive on the local computer does not work, you may have to burn it using a different computer. Does it read any optical disc at all?

If the ODD does not work then you will not be able to follow Toshiba's update instructions. You could then try handing the ISO to rufus and seeing if rufus can make sense of it enough to put the contents onto a flash drive. And then maybe see if your laptop can boot flash drives.

Try to stick with Toshiba's suggestion on using an optical disc, even if it means borrowing someone else's computer for a bit.

Edit: reasons

Thank you guys very much for your help I was able to create a BIOS DIsc, just needed the right software to create the disc. Will reboot and flash the BIOS and let you know ho it goes.

Okay so I do a system reboot, with DISC drive as boot priority and the disc runs and does its thing however I get a message saying "The battery not exists or lower than 20 percent". then press any key to shutdown the system. Is my battery basically toast? It is a laptop from 2010.

Most BIOS update software is picky. So just make sure to plug in the battery and also the laptop to the wall try it again. If you do not have a battery then it will likely not be possible to update the BIOS. Check e-bay for a replacement battery if needed.
