Why a bootable USB is your tech support lifesaver

When your computer starts acting up—whether it’s freezing, crashing, or refusing to boot—it can feel like you’re stuck in a tech nightmare. But don’t panic! A bootable USB drive is your ultimate tool to diagnose and fix these issues. Think of it as a portable tech support kit that fits in your pocket.

Creating a bootable USB is especially useful for Windows users. It allows you to run diagnostic tools, repair corrupted files, or even reinstall your operating system. Whether you’re a tech newbie or a seasoned pro, having a bootable USB on hand can save you time, money, and frustration.

In this guide I will show you how to create a bootable USB drive that you can use to diagnose computer and hardware issues.

Prerequisites

Before creating the bootable USB, you are going to need the following:

Instructions

Step 1

The first thing you need to do is download the Hiren’s BootCD PE ISO.

Hiren’s BootCD PE (Preinstallation Environment) is a restored edition of Hiren’s BootCD based on Windows 10 PE x64 that contains a variety of useful tools that can be used to fix many problems related to your computer.

Download HBCD_PE_x64.iso (2.88 GB) from the bottom of the Download page here: https://www.hirensbootcd.org/download/.

Step 2

After the Hiren’s BootCD download has finished, you will need to download the second tool, Ventoy.

Ventoy is an open source tool that is used to create a bootable USB drive for ISO and other disk image files.

What makes Ventoy different from other utilities is that you don’t need to format the disk over and over, you just need to copy the ISO file to the USB drive, and boot it directly.

Download the Ventoy software (ventoy-x.x.xx-windows.zip, 15 MB) from their GitHub repository here: https://github.com/ventoy/Ventoy/releases.

Extract/decompress the Ventoy package you just downloaded.

Step 3

Insert your USB Flash Drive into your computer.

Open the folder where you extracted Ventoy, and run Ventoy2Disk.exe

You should now be prompted with a screen from where you can install the Ventoy software.

Ventoy should auto-detect your USB Flash Drive, but if not, simply select it in the Device dropdown.

With your USB Flash Drive selected, click the Install button, and follow the prompts.

After a successful install, it will show that Ventoy is now installed on your USB Flash Drive.

Step 4

With Ventoy setup on your USB Flash Drive, you can now copy the Hiren’s BootCD ISO file to your Flash Drive.

Locate the HBCD_PE_x64.iso file that you downloaded, and simply copy it to your Flash Drive.

Step 5

Hiren’s BootCD PE is now successfully setup on your USB Flash Drive.

Go ahead and safely eject your Flash Drive from the current machine.

Next, insert your Flash Drive into the problematic computer, and select the boot from USB option when you start up your computer, and select your Flash Drive. (The boot selection option will vary from device to device, please check your computer or laptop manual. It is usually the ESC, F1, F2, F8 or F10 key).

After successfully booting from your Flash Drive, you should see the Hiren’s BootCD Preinstallation Environment.
