I was using YUMI to set up a multiboot USB drive. I had already had success when using YUMI to set up other multboot USB drives, but this time I was using a Philips 2GB USB drive, and for some reason it wasn’t working as well.
It worked OK when I installed a couple of recognized items onto the Philips USB drive. For instance, Ubuntu and Bitdefender were specifically listed in the YUMI installer’s list of programs that I could install, and those booted OK from the USB drive. But when I tried YUMI’s option to “Try an Unlisted ISO,” from the bottom of its selection list, it didn’t work. The other options were still there, when I booted the machine with the USB drive; but when I chose the “Directly Bootable ISOs or Windows XP” option at the bottom of the bootup menu, it gave me this:
Booting find /menu.lst, /boot/grub/menu.lst, /grub/menu.lst
That was with YUMI version 0.0.8.1. A search led to no helpful solutions. I wondered if an upgrade might solve the problem. The PenDriveLinux site was now offering version 0.0.9.5. I tried that. I installed Macrium Reflect as an Unlisted ISO on the Philips USB drive. Macrium was one of the programs that hadn’t worked in version 0.0.8.1, even after two tries. No joy: same problem. The upgrade wasn’t the solution.
I wondered if it was just the Philips drive. I tried the same procedure with a 4GB Kingston USB drive. When I booted with that, it worked, just as it had previously worked with a Patriot USB drive. So it was the Philips drive. I had already tried a full (not quick) format on the Philips, so that didn’t seem to be the problem. I had also used YUMI successfully with a much smaller (256MB) Lexar USB drive, among others, so it wasn’t that 2GB was too small. It was apparently just a problem with how the Philips was constructed. It seemed that it would work OK, as long as I didn’t try to use the Unlisted ISO option.
