Now that we have clarified that the BIOS update tool can be used with either Windows or DOS...
>> get a copy of RUFUS for Linux. > https://www.how2shout.com/tools/rufus-for-linux-not-available-use-these-best-alternatives.html Those tools are mostly for making bootable USB sticks from ISO images. ISO images are for making bootable CD or DVD, which explains why it helps to have extra tools to make ISO boot from USB sticks in case the BIOS does not detect what you are trying to do and helps you booting it anyway. However, the FreeDOS diskimage for bootable USB sticks is already MEANT for USB sticks, so you can avoid the hassle. As explained, you can just use "dd" to copy the raw image to the raw stick. I guess there also are other tools to do that using the mouse and some nice menus. If you are not experienced with dd, you can look up some tutorial about copying diskimages to USB sticks with it. Using dd the wrong way - as with all disk tools - could result in overwriting the wrong disk instead of your USB stick so you have to be a bit more careful when using dd. After you do that, the stick will contain one 32 MB FAT16 partition and bootable MBR and bootable DOS boot sector etc. to make everything boot FreeDOS once you boot from the stick. The only caveat is that the 32 MB are already full with FreeDOS stuff, but as soon as you open the stick again in Linux, you can simply use your file manager to throw 4DOS.ZIP away and instead add your BIOS file and BIOS update tool instead. Alternatively, you can use user friendly graphical tools such as GPARTED to make the partition larger (because your still will most likely be more than 32 MB) as long as you keep it as FAT16. Then again you will have space to add your BIOS file and BIOS update tool. When you boot from the stick, you can abort the option to install DOS to harddisk (of course) and instead run the BIOS update tool at your normal DOS prompt. I have no idea why your attempt to use Windows 7 to update the BIOS has failed, but I would say there are fewer unknown variables involved when you use DOS and not Windows to update your BIOS version. And I have no idea at all why you mention VirtualBox or VMware in context of your attempt to update your BIOS please explain that! Now that you have overwritten your Linux with Windows anyway, you could actually use the FreeDOS USB stick to install FreeDOS to harddisk. Then, copy the BIOS update and update tool to your DOS installation on harddisk: That is actually even more foolproof than running the tool on USB, because it will not depend on how well-behaved your BIOS is for USB access. You can just boot DOS from harddisk and do the BIOS update in a really classic DOS environment. I assume you do know how to run DOS apps? Simply type the name of the file you want to run and hit enter. There will be some documentation about the update tool as well, I assume. For example you may have to type something like NAMEOFTHETOOL NAMEOFTHEUPDATE instead of just NAMEOFTHETOOL.
