Create Windows 10 bootable USB from ISO on Mac without BootCamp

March 21st, 2019 by Admin

How can I make a bootable Windows installation USB on Mac OS X? After upgrading to macOS Mojave, you may find that Boot Camp Assistant is no longer supported and thus creating a bootable USB turns out to be a little bit challenging. In this tutorial we’ll show you how to create Windows 10 bootable USB from ISO on Mac, by using the Terminal or third-party software like UNetbottin.

Method 1: Create Windows 10 Bootable USB on Mac Using UNetbottin

UNetbootin is a free, open source utility that allows you to create bootable USB drives on Windows, Linux, and Mac OS X. If you’ve downloaded Windows 10 ISO image, here is how you can create a bootable Windows installer USB on Mac using UNetbootin.

  1. Plug a USB drive into your Mac and open Disk Utility. Select your USB drive from the left panel and click on Info button. Note down the device name since we will need that later.

  2. Next, download and launch the UNetbottin utility. Select the “Diskimage” radio button, click “” to select a bootable ISO image.

  3. After locating your Windows 10 ISO file, click on Open.

  4. Choose Type as USB Drive and select the device name of your USB drive (you probably would’ve noted it down earlier, so refer to that). Click OK to start installing to the USB drive.

  5. This process takes several minutes or longer, depending on the size of your selected ISO image.

Method 2: Create Windows 10 Bootable USB on Mac Using Terminal

Of course, if you prefer not to use third-party software, you can still use the excellent Terminal app, which is a little bit more involved, but no additional software needs to be installed. Follow these steps:

  1. After connecting a USB drive to your Mac, open a Terminal window and type diskutil list to display all the disks attached to your machine. You have to figure out the disk identifier of the USB drive you need to format. In my example, my USB drive is mounted as “disk2” and it’s about 32GB.

  2. Next, run the following command to format your USB drive and name it “WIN10“, where # is a placeholder for the disk identifier of your USB drive.
    diskutil eraseDisk MS-DOS "WIN10" GPT disk#

  3. Now, mount your Windows 10 ISO image with the command below, assuming it’s saved the Downloads folder. In my case, it is mounted as a volume named “ESD-ISO“.
    hdiutil mount ~/Downloads/your_windows_10_image.iso

  4. Finally, run the following command to copy all the files from the mounted ISO to your USB drive.
    cp -rp /Volumes/ESD-ISO/* /Volumes/WIN10/

    This command will take a while, and once it finishes, you can disconnect the mounted ISO with this command:
    hdiutil unmount /Volumes/ESD-ISO

  5. Now you should be able to boot from the USB to install Windows 10 on your Mac or Windows machine.


These should be the easiest ways to create a Windows 10 bootable USB from ISO on Mac, without using Boot Camp Assistant. No matter which method you prefer, be sure that you backup any important data on your USB drive, as the procedure of creating bootable USB will delete everything on it.

How to Securely Delete Files in Windows 10 without Third Party Software

March 18th, 2019 by Admin

When you delete a file, Windows only marks the file as deleted and it continues existing on your hard drive, even after you empty it from Recycle Bin. The deleted files can be recovered using data recovery software until they’re overwritten. In this tutorial we’ll show you how to use Microsoft’s command-line utility to securely delete, shred and wipe your files in Windows 10, so they can’t be recovered.

Part 1: Securely Delete Specific Folders or Files

To get started, download the SDelete utility from Microsoft’s website. After extracting the download file, copy the resulting .exe files to the System32 directory: C:\Windows\System32.

Open the elevated Command Prompt and you can securely and permanently delete any folder or file by running this command:
sdelete.exe -p 3 -s "your_folder_or_file"

By default, SDelete will overwrite the given file only once. You can use the –p option to specify the number of times to overwrite the data.

Part 2: Securely Wipe & Overwrite Free Space on Entire Drive

How can I overwrite the files that have been previously deleted without using the SDelete utility? To securely wipe all files and folders you have already deleted, simple run the following command to overwrite all free space on your drive. Replace D with the drive you want to clean up.
sdelete.exe -c:D

This command will only wipe the free space to prevent recovery of deleted files, and it won’t affect any files on your drive, so it’s safe. There is a similar built-in console tool called cipher.exe which also lets you wipe the free disk space, but it’s much slower than SDelete.
cipher /w:D


Using the SDelete utility you can securely delete files and wipe free space in Windows 10 to prevent any sensitive data from falling into the wrong hands. Despite SDelete does not have a graphical user interface, it is still easy for anyone to use.

What is difference between a BIOS password and a Windows password?

March 12th, 2019 by Admin

Can’t get past the password screen while the computer is booting? When you ran into this situation, it’s possible that you forgot the BIOS password or Windows password on your PC. In order to determine which type of password it is, you need to know the differences between a BIOS password and a Windows password.

BIOS Password:

BIOS (or UEFI) is non-volatile firmware used to perform hardware initialization before calling the boot loader to start the OS. BIOS has a setup utility which provides the ability to view and manage your computer’s hardware settings, such as changing the boot order or enabling CPU virtualization.

Through the BIOS Setup Utility, you can set up two different types of passwords:

  • Setup password: The computer will prompt for this password only when you are trying to access the BIOS Setup Utility. This password is also called “Admin password” or “Supervisor password” which is used to prevent others from changing your BIOS settings.
  • System Password: This will be prompted before the operating system can boot up. This password might also be called “User password” or “Power-on password” and it can stop someone powering up your computer.

If you forget any of these passwords, the reset process can be difficult or impossible. Depending on the motherboard of the computer in question, you can clear a lost BIOS password through jumper settings or removing the CMOS battery.

Windows Password:

Windows allows you to create separate accounts for different people to share a single PC. Each person can set a unique Windows password for their accounts to prevent unauthorized access.

If you forgot your Windows password and can’t log in to your PC, just boot your PC with PCUnlocker Live CD or USB and you can remove the password with ease.


BIOS password adds a hardware-level layer of security and locks the early stages of the startup process. After the BIOS passes the control to OS, you’ll see the Windows logo displayed on the screen. When your PC boots to the welcome/lock screen, you can click on the user name and sign in with a Windows password.
