Released in 2009, Windows 7 is still one of the most successful versions of Windows so far. However, many people will be wondering, 'Without a DVD installation disc, can I install Windows 7?'. The answer is yes, even just a very familiar tool, that is USB. So how to install Windows 7 with USB, please follow the instructions from A to Z below of Thuthuatphanmem.vn offline.

* In all of this guide, I defaulted the Windows 7 installation drive as C drive (by most users). If your installation drive has a different name, it's the same.

1. Check your computer configuration to install Windows 7

If you want to run Windows 7, your computer should have at least:

- 32-bit (x86) or 64-bit (x64) processor clocked at 1 GHz or faster

- RAM 1 GB (for 32-bit version) or RAM 2 GB (for 64-bit version)

- Hard disk with 16 GB free space (for 32-bit versions) or 20 GB (for 64-bit versions)

- DirectX 9 graphics device with WDDM 1.0 or higher driver

2. Prepare

- A 4GB capacity USB or higher

- ISO file of Windows 7 installation; If your computer hard drive is GPT, then download the ISO file of Windows 7 64-bit (see the standard hard drive in Part 4. Create a USB boot - Step 1 )

- Rufus USB boot software (download here)

- Store important files in USB and C drive to another place, because the next process will delete all files in USB and this drive.

- Preloaded automatic driver installation tool (such as Easy DriverPack ), stored on a drive other than drive C. Need to do this step before because after installing Windows 7, the computer can not connect to Wifi so then Cannot load (unless you have network cable).

3. Determine drive capacity C

- Check the total capacity and free space of the C drive (helps later to recognize where is the C drive to install Windows). Remember these numbers carefully (it is best to record them).

This can be checked in one of two ways:

+ Method 1: Open My Computer (or This PC , depending on the operating system).

+ Method 2: Press the key combination Windows + R , on the Run window type 'diskmgmt.msc' and press Enter .

As shown below, drive C is the drive with a total capacity of 30 GB and free space of about 10 GB.
