How Many DVDs Are Required to Create an ISO File of Windows 10?

Windows 10 ISO files come in a variety of sizes depending on the edition of Windows, and the general rule is that you typically need only one DVD to create an ISO file of Windows 10. The Windows 10 ISO file is usually around 4 to 5 GB in size, which fits comfortably on a standard single-layer DVD, which has a capacity of 4.7 GB. If you are using a dual-layer DVD, which can hold about 8.5 GB, you would still only need one DVD for a standard installation.

However, it's important to understand that the choice of DVD is not limited to just size alone. While a single-layer DVD is sufficient for most standard installations, it may not be adequate for multi-edition installations or if you need to write the ISO file as is to the disk. In these cases, you may require a dual-layer DVD or even a bootable USB drive for convenience and faster performance.

Different DVD Capacities

The capactiy of the DVD you choose is crucial. A DVD designed specifically for the x64 version of Windows 10 is around 4 GB. However, if you need a DVD that supports both x32 and x64 versions, you may require a much larger 695 GB DVD, which exceeds the capacity of a standard single-layer DVD. In such a scenario, using a dual-layer DVD would be necessary, as it can hold up to 8.5 GB.

Creating a Bootable DVD or USB

Though a single DVD can be used to create an ISO file of Windows 10, many users prefer to create a bootable USB drive instead. This can vary in capacity, but a standard 8 GB USB drive is generally enough to store the Windows 10 ISO and create a bootable USB drive. The bootable USB method is often more convenient and faster, providing a quicker and more reliable method to install Windows 10.

Conclusion

For the vast majority of Windows 10 installations, a single 4.7 GB DVD is sufficient. However, if you need to account for multiple editions or if you prefer a physical media backup, a dual-layer DVD (8.5 GB) is the preferred choice. Alternatively, for maximum convenience and performance, creating a bootable USB drive is often the recommended approach.

Whether you opt for a DVD or a USB, the key is to choose the medium that best suits your needs. For users looking for convenience, a USB drive is often the better choice, but for those with specific requirements, a dual-layer DVD might be necessary.
