YUMI (Your Universal Multiboot Integrator), is the successor to MultibootISOs. It can be used to create a Multiboot USB Flash Drive. which used grub to boot ISO files directly from USB, YUMI uses syslinux to boot extracted distributions stored on the USB device

But some USB flash drives are having problems after used from YUMI (e.g. doesn’t boot properly or black screen) the reason is some flash drives ship USB-FDD formatted not USB-HDD Mode

However you can change USB flash drives into USB-HDD Mode so the system will detect it and boot properly from it.

I recommend backup your data before proceeding this steps


Steps to change to USB-HDD

  1. Plug your USB Flash Drive ( Make sure no error detected )
  2. Open Bootice
  3. Select the Destination Disk Then click Parts Manage
    Step 1
  4. Select your Partition then select Re-Partitioning
    Step 2 
  5. Select USB-HDD mode ( Single Partition ) , Ignore the Start LBA and Reserved Secs
    Step 3
  6. Confirm your steps are true , select OK will repartition and format your FDD
    Step 4

Additional Notes

  • Make sure you have backup from your USB Flash Drive before repartition.
  • If the Instructions doesn’t work please try again or use U3 Launchpad Removal For SanDisk Cruzer (and similar) USB flash drives only
  • Change First Boot Priority or Boot Mode into USB-HDD as First in BIOS
  • If there are no USB-HDD or USB Mode in your BIOS you should use Plop Boot Manager from CD or DVD
  • I’ve tested this on my SanDisk Cruzer Blade 4GB (Not need a U3 Launchpad Removal)
