I use MKUSB and it works brilliantly for eOS Loki persistent live. However, I cannot work out how to edit the boot menu... I can't find grub.cfg (which I've done before, but not on a MKUSB persistent live). Anyone have experience with this? Ideally I want to bypass the boot menu altogether, so it just boots straight to eOS on any system.

  • Update: I looked at gparted and i appears there is a 1MB partition which may contain the GRUB config files. However I cannot mount sdb2 - it cannot identify the filesystem and says it may be "bad" - here's the output mount: /dev/sdb2 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so. – Craig Skipsey Jan 30 '17 at 19:18

the configuration file is at: /FAT32_PARTITION/boot/grub.cfg

How I found out where the files are:
By looking for the strings I see in the GRUB menu in the raw data on the USB drive, I found that the configuration files are located in a partition called "usbboot", which is FAT32 (the second partition in your screenshot, which is has a different name in your case, since I had this problem with Ubuntu).
