You may use E2B and any included utilities or any helper utilities from this site 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 associated utilities.
Easy2Boot is Freeware/Donationware
Easy2Boot mainly consists of grub4dos, grub4dos utilities and grub4dos scripts and these can be freely used by anyone (freeware).
Also, because E2B uses grub4dos scripts (.lst, .cfg, .g4b), it is mostly 'open source' because these files are the 'source' files as are the various .cmd Windows scripts in E2B.
A few Windows executables (Make_E2B.exe, E2B_Editor.exe, Make_Ext.exe, Txt_Maker.exe, Switch_E2B.exe, etc. - see list below) are not open source and are my intellectual property. If you only want to use open source software, then make the E2B USB drive using Linux.
Private home users, public or private schools, Universities, businesses, technicians within any company (even if a one-man+dog company or a company with 1000's of employees) are free to use E2B - just don't sell E2B, don't include it in a product you are selling and don't re-distribute it publicly!
If you wish to use my E2B grub4dos scripts or programs commercially however (i.e. sell it in it's entirety or as part of your own product) you will need to contact me for permission or a licensing arrangement. You should not sell ready-made E2B USB drives (e.g. sell E2B multiboot USB drives on eBay) without contacting me first for permission or a licence.
The E2B downloads also contain small third-party Windows programs which may not be free to use commercially and it is up to you to obtain permission for all .exe programs within the E2B download that you may use (see list below). The author of WinContig.exe states it is free for commercial use.
The Easy2Boot download also contains RMPartUSB (used to format a USB drive) which is freeware but cannot be sold or re-distributed (see below) - however it is only used to partition a USB drive and other utilties can be used to format a USB drive and install grub4dos (e.g. BootIce or FBInst).
The MPI Tool Kit also contains some 3rd-party utilities which AFAIK are freeware (but not all are open source).
Please do not re-distribute the E2B download packages or the MPI Tool Kit. Instead just link to this site.
Some of the E2B Windows utilities that I have written are not open source but can be freely used or distributed (but not sold). XMLtoE2B requires a licence file which contains the user's name and email address - the licence.bin file should not be distributed with XMLtoE2B.
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 or redistributed or made available for download, either as a standalone download or as part of a package, 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).
