With iVentoy, you can start and install operating systems. This means that multiple operating systems can run simultaneously even though they do not have their own physical data carriers.
All you have to do is copy the widely available ISO files of the operating systems to the designated folder, activate PXE boot on the target device, and you're done!
Whether classic BIOS systems or modern UEFI architectures, iVentoy supports all common standards: x86 Legacy, IA32 UEFI, x86_64 UEFI, ARM64 UEFI.
