On Weekend Roundup #135, I mentioned that my wife’s Asus Eee 1005HAB was broken and that I was trying to fix it. One of the things I did to try to fix it was to flash the BIOS and since the netbook didn’t have a DVD/CD ROM drive, I had to do it via USB. To do that, I had to have a bootable USB drive or USB key. Creating a bootable USB drive is fast and easy but I know that some people don’t know how to do it or aren’t technologically knowledgeable, so I decided to write and share this short and simple tutorial.
How To Create a Bootable USB Drive
To make sure that all the right files were copied into the USB key, browse into the USB key and check that the following files are there – COMMAND.COM, IO.SYS and MSDOS.SYS. In you don’t see the files, you’ll have to make sure that your system allows you to view protected operating system files.
To do that, go to Control Panel > Appearance and Personalization > Folder Options. Click on the View tab and look for “Hide protected operating system files (Recommended)” and uncheck it. You should now be able to see the DOS system files inside the USB key. If you want, you can go back and put a check back on “Hide protected operating system files (Recommended)“.
Btw, for CDROM support, copy all the Windows 98 system files and the CDROM folder (folder and files in Step #3) into the USB key. Doing so will not only enable CDROM support but also mouse support for any DOS programs that have this feature.
Hope this tutorial on how to create a bootable USB drive will be useful and helpful in case you need to create a bootable USB key to fix your computer or flash the computer BIOS.
