Why make a Bootable USB for Windows 7?

why create a windows 7 boot usb

A Windows 7 iso bootable USB saves you the trouble of burning a Windows ISO file to a DVD (CDs don’t have sufficient storage). Besides being more inconvenient, DVDs are more prone to damage than USB drives; merely scratching them would render them unplayable.

Moreover, newer computers don’t have CD/DVD drives, making a bootable USB your only viable option for installing Windows. Let’s see what items and tools you need for a Windows 7 USB boot.

What You Need to make a bootable USB for Windows 7

A Windows 7 USB boot requires the following items.

USB Flash Drive

Installing Windows 7 from a bootable USB requires a blank USB flash drive with at least 4 GB of space for a 32-bit processor or 8 GB for a 64-bit architecture. However, some tools require a minimum of 8 GB, regardless of the CPU.

Official Windows 7

Purchasing the official Windows 7 ISO file from Microsoft Store is necessary to install the OS. However, Microsoft has ended the Windows 7 support, so you can’t find direct download links on the official site.

Fortunately, we’ve found magnet links for Windows 7 versions (original files on a secure server), but you’ll need a valid product key to activate Windows. Hopefully, you’ve written yours down when initially installing your OS.

Rufus or Windows USB/DVD Download Tool

Third-party software like Rufus or Windows USB/DVD Download Tool will help you make a bootable USB for Windows 7. Rufus can also download a Windows 7 ISO file for you.

Moreover, your computer has a built-in tool (Command Prompt) that can help you create a bootable USB.
