Summary [TL;DR] - Free to use by everyone but not sell.
E2B download also contains bundled open-source GPL utilities plus my own Windows utilities which are closed-source but the sources can be requested. The E2B Menu system itself only uses Open Source components (grub4dos) + plain text scripts. The UEFI File Manager (agFM) contains a1ive's version of grub2 and the grub2 File Manager (both Open Source on GitHub). Ventoy sources are also Open Source and on GitHub too.
You may use E2B and the included utilities or any helper utilities at your own risk. I can accept no liability for any loss of data or other damage which may arise through use or misuse of any part of E2B or it's included utilities. Some scripts\utilities can destroy all data on a drive, so make sure you pick the correct drive!
About the E2B project
The Easy2Boot project download is FREE and is currently available as a self-extracting .exe or a .zip file.
The Easy2Boot menu system uses grub4dos and a few other unmodified GPL-licensed grub4dos programs. The E2B menu system is open-source and is comprised of plain-text grub4dos batch\menu files.
The complete E2B download also includes some of my own Windows .exe utilities and other unaltered 3rd-party software binaries which are aggregated/included in the download bundle for the convenience of the user. These are not used by the E2B menu system but can be used to make, modify and maintain your E2B USB drive.
Note: All 3rd-party free/licensed binaries included in the downloads are original and unmodified. My Windows .exe executables (see below) are not used by the E2B Menu system itself and you can delete them if you really want to - the E2B Menu system will still work without them. A few of my utilities call some unaltered, freely available, GPL-licensed executables via a command line interface and are thus not required to be licensed under GPL (refa, ref1, ref2) and so I am not required to provide the source code for them. Due to the space considerations of USB Flash drives, I only provide links to the source code to the bundled 3rd-party GPL utilities. This is in line with many other GPL multiboot utilities such as AIOBoot, YUMI, XBOOT, Unetbootin, MultiBootUSB, etc. which also do not include the complete source code of grub4dos, syslinux or all the other GPL binaries they contain neither do they make the sources of these additional GPL utilities available on their own repositories (the GPL sources are of course easily available elsewhere). Although the VB6 source code for my utilities is not made publicly available, developers can request a copy as long as they do not distribute or alter the sources (a small charge will be requested to cover my costs/time). Please use the Contact Me form or Live Chat if you have any concerns or requests.
Easy2Boot is Freeware/Donationware
The Easy2Boot menu system mainly consists of grub4dos, grub4dos utilities (GPL) and grub4dos scripts and these can be freely used by anyone (freeware).
Also, because E2B uses grub4dos scripts (.lst, .cfg, .g4b), these files are the actual 'source' files of the E2B Menu system as are the various .cmd Windows scripts in E2B. Anyone - private home users, public or private schools, Universities, businesses, technicians within any company (even a one-man & a cat company or a company with 1000's of employees) - can use the E2B Menu System and the E2B utilities. However, you should not sell the original E2B s/w components (e.g. sell E2B multiboot USB drives on eBay) without contacting me first for permission or a licence to sell my E2B scripts/batch files or my executables (this does not affect your rights with any GPL or other 3rd party licensed s/w). A few 3rd-party grub4dos scripts in the E2B menu system carry a 'not for commercial use' restriction by their respective authors.
Please do not re-distribute the E2B download packages or the MPI Tool Kit. Instead just link to this site.
RMPrepUSB and RMPartUSB*
RMPrepUSB and RMPartUSB are not open-source. These two programs are free for public use, but should not be used within a commercial product without permission. Note that the MPI Tool Kit contains RMPartUSB.exe and so will any .imgPTN images made using it (though you can remove it as it is not essential).
