I recently bought an LG laptop, and im looking to install the latest UBUNTU LTS on it. I used rufus to create a bootable usb using FAT32 file format. It doesnt show up in boot menu list. It only appears on boot menu when i create the USB using NTFS file format, but it wont load ubuntu, and leads me to a black screen, "Minimal bash like line editing is supported..." I managed to find a korean article online with a person with the exact same problem as me, and he managed to solve it by reading the grub bootloader off 1 NTFS usb drive and ubuntu files on a FAT32 drive.
I just want to know how you can read the grub bootloader off of another usb drive. Any steps and instructions would be extremely helpful. Thank you!
