Easy2Boot is a set of grub4dos files which can be used to make a grub4dos bootable (multiboot) USB Flash drive (or USB hard drive - read below for more details about Easy2Boot USB HDDs).
By simply copying bootable ISOs and images to the Easy2Boot USB Flash drive you can then boot from the USB drive and boot directly from those ISOs or images. No menu editing or other fiddling about required. No special s/w needed. Just copy your payload files and go! Watch the YouTube video below. It even shows how to boot directly from linux ISO files with persistence!
E2B is easy to maintain, just delete any payload file you no longer want. Since the menu will build itself when you boot, you don't need to worry about editing any menu files. It is also easy to update to the latest version (just takes a few seconds), so no need to re-make your E2B USB drive to get the latest version.
Easy2Boot should work with 99% of all linux ISOs (even those that need cheat codes or don't have any cheat codes for ISO booting and so could not be booted by grub4dos before Easy2Boot!) and many other live CD images such as BartPE, Win7PE, WIn8PE, Hirens, UBCD4Win, UBCD, Plop!, memdisk, etc. etc. . Also, works with XP and later Windows install ISOs too. Apart from Windows ISO files, the action taken is based on the file extension. For instance, a Hirens ISO will boot more successfully if you rename the extension to .isowinvH.
You can also add a .mnu file for the more difficult ISOs/images (sample .mnu files are included in the \docs folder of the download and more can be downloaded from the Easy2Boot Tutorial page - each file contains instructions). More information can be found on the E2B website.
Easy2Boot does not care about the version or name of the linux ISOs (unless you use a .mnu file) and so will work with linux ISOs that come out in the future.
Easy2Boot is designed for a USB Flash drive. You can use Easy2Boot V1 from a USB hard disk too (FAT32 or NTFS), but to use the Windows Install ISOs, you also need to plug in a USB flash drive which contains two small files in the root of the drive - see the web page for more info.
Standard MS Windows Install ISOs can currently be added to an Easy2Boot USB flash drive and they should automatically work (as long as the filename is correct): See HERE for a list of Windows ISOs that should 'just work'. You can have 16 or more Windows install ISOs on the same USB drive and they will all work.
If you always want to use the same Win 8/SVR2012 Product Keys, you can edit the appropriate grub4dos menu in the \grub folder to add in your Product Keys.
Your Windows Install ISOs should be placed in the \_ISO\Windows folder and have specific names (although the user can pick from any number of different ISOs in the Win7/SVR2K8/SVR2012 folders) - it should be obvious where each one goes and what to name them.
Latest versions support direct booting of VHD and WIM files, UEFI booting from .imgPTN files (Secure boot supported), exFAT, FAT32 and NTFS formats, animation, large fonts, menu designer, boot from multiple linux ISOs with persistence, multiple WindowsToGo payloads and much more.
