About this app

BootStick turns your Android phone into a bootable USB maker. Write an ISO to USB without a PC or root.
Create Windows 10 and 11 installer drives for UEFI PCs, or write Linux ISO and IMG images to a USB flash drive over OTG.

MAKE A BOOTABLE USB FROM YOUR PHONE

Laptop won't start and no computer nearby? Connect a USB stick or pendrive with a USB OTG cable or adapter, choose an image, confirm the drive and start writing. BootStick is a simple ISO writer for Android phones and tablets with USB OTG, running Android 7.0 or newer.

WINDOWS 10 AND 11 USB INSTALLER

• Choose an official Windows 10 or Windows 11 ISO downloaded to your phone.
• BootStick prepares a FAT32 USB installer and automatically splits a large install.wim file.
• Your Windows bootable USB is ready for UEFI PCs, which covers nearly all PCs since 2012.

LINUX ISO BURNER AND IMG WRITER

• Burn a Linux ISO or write a raw IMG disk image, block by block, to a bootable flash drive.
• Use .iso and .img files, including .gz, .xz and .zip compressed images, which are unpacked as they are written.
• Prepare a Linux live USB, a recovery USB for PC repair, or OS installation media.

CHECK AND VERIFY YOUR USB

• Find out whether an image can boot from USB before you write it, with warnings for unrecognized or oversized files.
• Every block is read back after writing to verify the result.
• See the image's SHA-256 checksum and compare it with the publisher's value.
• Follow the progress, writing speed and time left. Writing continues in the background and with the screen off, and you can cancel at any time.

RESTORE YOUR FLASH DRIVE FOR FREE

Finished with your bootable USB? Restore it to one normal, empty FAT32 drive that works on phones and computers. BootStick names the selected drive and asks before erasing it. Only USB drives are listed, so your phone's own storage cannot be picked by mistake.

OFFICIAL IMAGE LINKS AND BOOT HELP

Find links to the official download pages for Windows, Ubuntu, Linux Mint, Zorin OS, Fedora, Debian, Arch Linux, Kali Linux, Tails, GParted Live, Clonezilla and Raspberry Pi OS. Download your image in a browser, then select it in BootStick.

A built-in boot guide lists the boot menu keys for common PC brands, with fixes for Secure Boot, USB ports and 64-bit systems. If a drive is unplugged, write-protected or failing, or a download is damaged, BootStick tells you what went wrong and what to try next.
