Hi, I have Lubuntu on an 3 year old HP laptop. Now I want to switch to Manjaro. Im trying to make a bootable USB but it dosen´t work. I use the dd command, I tried 3 different USB sticks. I used unetbooting, ubuntu usb stick. Nothing works. I had the same problem installing Lubuntu. Is it always this hard? I have been trying for hours!
Are you doing dd if=/path/to/iso of=/dev/SDB without any numbers at the end? Because if you using it like this: /dev/sdb1, that will create the mbr for the stick at the beginning of the first partition, not on the first 512 bytes of the thumb drive, where the bios looks for the boot data.
As a side note, it can be /dev/sdc or /dev/sdd, that depends on the number of drives, it's fine as long as you don't put any number at the end.
