One for live USB and another one where Linux will be installed. Let me clear a few more doubts and add some suggestions: The original ESP partition on the hard disk is untouched.Ĭlever trick, I know. This way, you fool the Ubuntu installer into thinking that there is no existing ESP partition and it will create and use a new ESP partition on the USB. Removing the disk is out of question here.Īn easier way out is to remove the ESP flag from the ESP partition before installing Linux on the USB and put it back after installation. If you have a desktop PC, you may remove the hard disk and that could solve the problem but things will be difficult when it is a laptop.
The solution or workaround to the bootloader problem is that you do not let the installer know that there is already an ESP partition.
