Guys I have been beating my brains out trying to figure out what I am doing wrong. Normally, I could do this task in my sleep but not today. Task - simply to create a bootable USB for running grub4dos and some menu files I have used for quite some time. This is to be used on a windows machine and I even want to prepare the flash on the same machine. Before you tell me its the hardware (USB flash) please note that I have been using this exact hardware for many months without issues. I decided to grab a current version of grub4dos to be able to employ some of the newer grub functions not available in older versions. That said I formatted the flash using windows and did it the slow way not quick format. In the past I used the grubinst-gui.exe and created this bootable version directly to this flash, but not using this computer. grub4dos has always worked well on this device. I used the same method to create the new flash but when I try to use it I get the "missing mbr-helper" flag and the process stops. Next, I formatted the flash again and tried to write back the older (exact same) version that has always worked. Again, same missing mbr-helper flag. Frustrated I grabbed Easy2boot and install it directly on my system disk. Fire it up and to my surprise it doesn't even see any USB at all. It doesn't see any of my flash OR usb external drives at all. Darn it! Then I grab RMprepUSB portable. I fire it up and same thing. No flash is seen at all. WTF? You guys think this machine has something going on? I can't get to another machine until tomorrow. Would this machine being 64 bit have anything to do with this process. It may be that the flash was created on a 32 bit machine some time ago. Answers or ideas appreciated.
