Most tools do Windows or Mac. BootIt does both, natively, from your Mac — and bundles everything it needs.
Download an ISO straight from Microsoft (edition + language) or use your own, written to a UEFI-bootable FAT32/MBR drive. Optional one-click bypass of the Windows 11 TPM, Secure Boot & RAM checks.
Download any macOS installer Apple offers, or use an “Install macOS …” app you already have, then build the drive with Apple’s own createinstallmedia.
A tiny (~3 MB) native app that bundles everything it needs. No Homebrew, no Terminal, no extra installs. Splits oversized install.wim files automatically.
MIT licensed, no subscriptions, no telemetry. Downloads come direct from Microsoft’s and Apple’s official servers — BootIt never touches your data.
Choose Windows or macOS, then download from the vendor or point at a file you already have.
Only external drives are listed — your internal disk is never shown. Confirm the erase.
BootIt formats and writes a fully bootable installer, then verifies the boot files.
A signed-by-you-or-not, notarisation-free little app. Free, forever.
