When you download Windows 7 from MSDN or from Microsoft, it might be in ISO format. You will need to burn the ISO file to a DVD and then start installing. Microsoft has released a new tool which will convert your ISO files to USB or DVD. The Windows 7 USB/DVD Download tool allows you to create a copy of your Windows 7 ISO file on a USB flash drive or a DVD. To create a bootable DVD or USB flash drive, download the ISO file and then run the Windows 7 USB/DVD Download tool. Once this is done, you can install Windows 7 directly from the USB flash drive or DVD.
The copy of the ISO file that the Windows 7 USB/DVD Download tool creates is bootable. Bootable media allows you to install Windows 7 without having to first run an existing operating system on your machine. If you change the boot order of drives in your computer’s BIOS, you can run the Windows 7 installation directly from your USB flash drive or DVD when you turn on your computer.
To make a copy of your Windows 7 ISO file:
- Click the Windows Start button, and click Windows 7 USB/DVD Download tool in the All Programs list to open the Windows 7 USB/DVD Download tool.
- In the Source File box, type the name and path of your Windows 7 ISO file, or click Browse and select the file in the Open dialog box.
- Select USB to create a copy on a USB flash drive or DVD to create a copy on a DVD disk, then click Next.
- If you are copying the file to a USB flash drive, select your USB device in the dropdown list and click Begin copying. If you are copying the file up to a DVD, click Begin burning.
