How to Make a Bootable USB Pendrive

Creating a bootable USB drive allows you to install or run an operating system from the USB. Here are methods for Windows, macOS, and Linux:

For Windows

2. Insert your USB drive (min 8GB recommended)

3. Open Rufus and select your USB device

4. Select the ISO file (click "SELECT" and browse to your OS ISO)

5. Partition scheme:

   • For modern PCs: GPT (for UEFI)

   • For older PCs: MBR (for BIOS/Legacy)

6. File system: FAT32 (for UEFI) or NTFS

7. Click START and wait for completion

Method 2: Using Windows Media Creation Tool (for Windows OS)

1. Download Media Creation Tool from Microsoft

2. Run the tool and select "Create installation media"

3. Choose language, edition, and architecture

4. Select "USB flash drive" option

5. Pick your USB drive and wait for completion

For macOS

Using Terminal

1. Download macOS installer from App Store

2. Insert USB drive (min 16GB recommended)

3. Open Disk Utility and erase the USB:

   • Format: Mac OS Extended (Journaled)

   • Scheme: GUID Partition Map

4. Open Terminal and run:

   bash

   Copy

   Download

   sudo /Applications/Install\ macOS\ [Version].app/Contents/Resources/createinstallmedia --volume /Volumes/[USBName]

   (Replace [Version] and [USBName] with actual values)

For Linux

Using dd Command

1. Identify your USB with lsblk or sudo fdisk -l

2. Unmount the USB (if mounted):

   bash

   Copy

   Download

   sudo umount /dev/sdX

   (replace X with your drive letter)

3. Write the ISO:

   bash

   Copy

   Download

   sudo dd if=your-distro.iso of=/dev/sdX bs=4M status=progress oflag=sync

4. Wait for completion (no progress bar - be patient)

Universal Tools (Cross-Platform)

• Balena Etcher (Windows/macOS/Linux)

  1. Download from etcher.io

  2. Select ISO image

  3. Select USB drive

  4. Click "Flash!"

Important Notes:

1. Backup USB data first - the process will erase everything

2. Use high-quality USB 3.0 drives for better performance

3. For Windows 11, you may need to disable Secure Boot or enable TPM in BIOS

4. For Linux distributions, verify ISO checksum after download

5. Some tools may label the process differently ("Burn", "Flash", "Write")
