UEFI-multiboot for E2B now supports UEFI 32-bit and 64-bit

I have made a dual WinPE partition image for use with Easy2Boot X4 files.
This allows you to select and boot from a variety of UEFI payloads on an E2B USB drive without the need to Legacy\CSM-boot or find another Windows system to run SWITCH_E2B.exe.

Here is how to do it...

Requirements

1. Latest version of E2B
2. Latest version of the MPI Tool Kit
3. Latest version of SWITCHPE_x32_x64 (see eBook #3 for download link)
4. A variety of UEFI32-bootable and UEFI64-bootable payloads (e.g. ISO files converted to .imgPTN23 files)

Method

1. Download the SWITCHPE_x32_x64 zip file and extract the file which is inside it. You can rename the file if you wish.
2. Copy the SWITCHPE_x32_x64 file to the \_ISO folder on the 2nd Primary NTFS partition of your E2B USB drive. If you don't want to make a 2nd partition, you can use the \_ISO folder on the E2B partition, but this may cause problems because SWITCH_E2B.exe may need to move the files so that they are in the correct order. I strongly recommend you delete the small 31K 2nd partition and create a larger (say 1GB+) NTFS Primary partition on your E2B drive.
3. Use the MPI_FAT32 shortcut to convert each of your payloads to .imgPTN files. Answer R for REFIND when prompted. If you have already made .imgPTN files which include REFIND, you do not need to remake them.
   Note: Even if the payloads are not UEFI-bootable, you may want to add REFIND into them in case you need to boot the USB drive from a UEFI-only system.
4. Copy the .imgPTN files to your E2B menu folders and change their file extension to .imgptnX4switchpe_x32_x64, or use .imgptnautoX4switchpe_x32_x64 if you don't want to be prompted by E2B to switch.

E2B: \_ISO\MAINMENU\Ubuntu64.imgptnX4switchpe_x32_x64

Ptn2: \_ISO\switchpe_x32_x64

Be aware that adding REFIND into a .imgPTN file will break Secure UEFI booting. You can still however Secure Boot by enrolling the \refind.cer key file using Mok Manager. However, this is not always reliable and it does update the target system's NVRAM and make it less Secure.

Usage

You must select the first .imgPTNX4 image before you can UEFI-boot from any system. This can be done by Legacy\CSM-booting to the E2B menu and selecting any .imgptnX4 file, or by running SWITCH_E2B from any Windows system

Once you have switched in the .imgPTNX4 file, you can UEFI-boot to the payload (e.g. UEFI64-boot if the payload and system are both UEFI64, or UEFI32-boot if both payload and system are UEFI-32). You can also boot to WinPE on both UEFI32 and UEFI64 systems and then run SWITCH_E2B.exe to restore the E2B partitions and then (if required) select another .imgPTNX4 file.

First select an 'X4SwitchPE_x32_x64 image

How to UEFI-boot from the E2B USB drive to start with

The above system must be first started by switching to a .imgPTNX4 file first. This may not always be possible however if you find yourself confronted by a UEFI-only system and have no other Windows system available to run SWITCH_E2B.exe on.

There is a simple way to add the WinPE files to your E2B drive so that it will MBR-boot to the E2B menu or UEFI-boot to WinPE where you can run SWITCH_E2B.exe and switch in any .imgPTN file.
