Make sure that’s what you want to do and click OK.Įxactly how long this takes will vary depending on the size of the ISO you’re writing, the speed of your hard disk, the speed of your flash drive, and whether you’re using a USB 2 or 3 interface.Īfter all is said and done, you have a bootable USB flash drive. This operation erases everything that’s currently on the USB flash drive and replaces it with the contents of the ISO. In the example below, I’ve inserted an unlabeled USB thumb drive that appears as “E:”, and I’ve selected the file HBCD_PE_圆4.iso (the most recent Hiren’s Boot CD), that I’d downloaded previously. iso file you want to copy to this USB thumb drive.

Under “Boot selection”, use the Select button to locate the. Step 4: Launch Windows 7 USB/DVD Download Tool, click the Browse button to browse to the folder where Windows 10 ISO image file is located. If none appear, make sure you’ve inserted one and Windows recognizes its presence. Under “Device”, select the USB thumb drive you want used. There are actually several tools, but one I’ve run across that seems to do the job simply and well is called Rufus.ĭownload and run Rufus directly from the Rufus website. More and more machines are coming without optical drives - that is, they don’t have the ability to read a CD or DVD, much less boot from it.įortunately, there are tools we can use to take an ISO that contains a bootable image and place it on a USB thumb drive from which you can boot. A good example might be operating system installation DVDs. In either case, we would then boot from the CD or DVD to run whatever the software provided. As the ISOs themselves became larger, we’d burn them to DVDs instead. That will tell you if its the CD or BIOS.ISO files are disk images often used to distribute software. One fallback/test option is to remove all the other drives from the system, and see if the bios/boot falls back to a optical drive boot when no other devices are found. So what you are most likely looking for is enabling the system to boot from a legacy optical drive which may not be an option from the bios. Its that 'legacy optical boot' being automatically disabled is what is probably causing your problems. The systems are designed to be reverse compatible with old boot disks, which makes 'converting the Cd to EUFI' irrelevant. The OEM Windows has to be booted, and the drive order enabled and changed from there! That presents a mess of catch-22. some Toshiba's dont' even give the option to change that in the bios. but that probably won't work for you.īecause, what I usually find (and why I use the USB) is that many systems come with the boot-to-optical drive disabled. If you are looking for a read only copy (CD/DVD), there are tools that can make a EUFI bootable CD and then copy the files over. It boots on my new system and works on all the computers I get in for repairs.
