You cannot specify too many 'set' commands in your MyE2B.cfg file or you may get strange grub4dos errors.
grub4dos allows for a limited number of environment variables (approx 60). Make sure your BIOS is configured to MBR-boot (BIOS has CSM enabled). If you are having a problem with one particular payload file - delete the. If there is a STRINGS.txt or MENU.LST file in the \_ISO folder, then delete it. Delete or rename the \_ISO\MyE2B.cfg file, if it exists - some settings may adversely affect E2B or hide informational messages. Ensure the MBR partition table contains two primary partitions (RMPrepUSB - Drive Info - 0). Check the E2B Version History for a new Beta version + bug fixes. Download the LATEST VERSION OF E2B to a new folder and run the UPDATE_E2B_DRIVE.cmd script to update your E2B drive. If you did not make the E2B USB drive using the Make_E2B_USB_Drive.cmd batch file, make a fresh USB drive using it.
How to prepare a Easy2Boot USB drive using FlashBoot
Please click here to test a time-limited trial version and see if it works for you. I recommend FlashBoot if you need to create a USB drive that will boot on these badly behaved systems.
RMPrepUSB can make most USB drives bootable and includes a specially modified version of grubinst.exe, but some older BIOSes may have problems booting from USB devices.
