Hi All, I am trying to clone a bootable USB key B ( FAT32) I format USB key C and set the boot flag. Copied all files from USB-B to USB-C in Windows. Copied the MBR: dd if=/dev/sdb of=/dev/sdc bs=446 count =1 When I boot from USB-B I get only the word GRUB in the left upper corner. I noticed: USB-B has an icon in the browser , USB-C has not. What could be wrong ? Thanks.
