To get your hands on this handy tool, head over to the following link: and grab the “Hiren’s BootCD 15.2” ISO file.

Once the download is complete, unzip the compressed file and extract its contents into a designated folder. Inside this folder, you’ll spot an ISO file. Now, to move forward, you’ll need another utility software capable of creating a bootable flash drive from this ISO file. This step is crucial to unleashing the power of Hiren’s BootCD on your system.

Once you’ve successfully transformed your flash drive into a bootable powerhouse using the Hirens BootCD ISO file, the next move is to boot your computer from this flash drive. You can achieve this using a feature commonly known as the “Boot Menu”, nestled within your computer’s BIOS settings.

The “Boot Menu” is a specific feature housed in the BIOS (Basic Input/Output System) of your computer. It allows you to select a boot device other than the default hard drive. This menu showcases a list of all available bootable devices connected to your computer, such as USB flash drives, external hard drives, DVDs, and the like.

To kickstart your computer from a flash drive using the Boot Menu, follow these simple steps:

  1. Power on your computer and be vigilant for a brief moment just before the operating system begins loading. This is your window to access the BIOS or Boot Menu. The key to enter this menu varies depending on your computer’s manufacturer—common keys include Esc, F2, F8, F10, F12, or Del. Keep an eye out for an on-screen prompt indicating which key to press.
  2. Press the appropriate key during startup to access the Boot Menu. This action will unveil a list of available bootable devices.
  3. Use the arrow keys on your keyboard to navigate the Boot Menu and select your USB flash drive or the bootable drive containing the Hirens BootCD.

Note: In case you’re facing hurdles in accessing the boot menu? Fear not, as there’s a practical workaround that involves temporarily disconnecting all internal storage devices like HDD and SSD from your computer’s motherboard. The trick here is to maintain a sole connection to the bootable flash drive that you’ve recently crafted. By isolating the bootable drive, your computer will automatically prioritize it as the sole available bootable device. This nifty maneuver eliminates the need to manually configure the flash drive as the primary boot device in the system settings. This approach streamlines the boot process, enabling your computer to effortlessly recognize and kickstart the startup sequence from the connected flash drive.

Alright, so you’ve successfully booted up your USB drive, and now you’re greeted by the welcoming screen of the Hirens Boot CD menu – a treasure trove of options waiting for your exploration. Now, let’s dive into the fun stuff. Go ahead and choose ‘Dos Programs’ to reveal a lineup of tools that are like the superheroes of system-related tasks and troubleshooting.

Now that you’re in the ‘Dos Programs’ section, keep hitting that ‘Next…’ option until you land in the ‘BIOS/CMOS tools’ section. This is where the magic happens for tweaking BIOS settings and dealing with passwords. Dive into this part, and you’ll find a toolbox filled with gadgets designed to mess around with BIOS or UEFI configurations.

What you’re looking for in the ‘BIOS/CMOS tools’ section is the ‘BIOS Cracker 5.0 (cmospwd)’ tool. It’s your go-to hero for tackling BIOS-related headaches, offering ways to crack, bypass, or reset BIOS/UEFI passwords.
