I managed to install GRUB to my local hard drive instead of my usb. So I have an ext4 stick with 128GB dedicated to Ubuntu, but I am only able to boot from the usb on a pc with already installed grub....

Can I Install Grub on the USB now afterwards? Does this work with boot-repair too? I hope this question isn't duplicate, as I saw similar questions like this:Accidently installed grub to usb If this procedure applies to my problem too just let me know

Ok I managed to fix it like this with a second live usb:

  1. Boot from the new ubuntu live usb
  2. Install grub on the problem usb (according to this answer https://askubuntu.com/a/153083/890260)

Now boot from the "not any longer" problem usb. If you encounter a problem (after 90s not booting, emergency mode):

  1. Boot in recovery mode, look which disk is shown as waiting task (dev-disk....numbers)
  2. Boot again from the live usb and let the still problem usb in
  3. Edit the /etc/fstab file from the problem usb by commenting out that disk shown in recovery mode as waiting ..... (commenting by "#" + "Space")

This worked for my problem at least..
