Debian-based distribution does not install the EFI boot file in the right location, but it is easy to fix

This is the procedure for Debian, adapt for Ubuntu

Exit the shell
Shell> exit

Navigate in the menu of the EFI boot manager

• Boot Maintenance Manager
• Boot from file
  • <NO VOLUME LABEL ... GPT ...>
  • <EFI>
  • <debian>
  • <grubx64.efi>

Now GRUB appears and the system boots

• Login as root and type the following commands to fix the EFI boot issue

Code:

mkdir -p /boot/efi/EFI/BOOT/
cp /boot/efi/EFI/debian/grubx64.efi /boot/efi/EFI/BOOT/bootx64.efi

From this step, i just press ENTER?

whenever i install any linux OS, after install or before, like with ubuntu, i get prompted with this:

@marinusx If you have this problem when running a live ubuntu CD, before any installation takes place, thats suggest some other config problem when creating a VM in FreeNAS. Your ISO location is a bad choice, keep your VM iso out of the iocage dataset as that's intended or FreeNAS jails. Create separate dataset(s) as necessary for VM ISOs and zvols. For Ubuntu at least, your shouldn't need the post-install fix metioned above. For debian, it's not necessary if you choose the advanced install and say yes when prompted to install GRUB on the removable media path.

so i jsut gotta change the install location?

and how do i remove files in that location? i am new to truenas

could this also be a cause of a slow VM?

 

[blanchet]

If you do not see the grubx64.efi file in the EFI Boot manager, it may comes from the virtual hard disk sector size.
Edit the Disk Sector Size and try to force the sector size to 512 or 4096 (try both to see that is the good value).
You have to power off the VM before changing the sector size.

Keep your ISO files out of the iocage dataset path. Choose an install location of a dataset whose properties you can set on its creation. Slow VM? Define slow, that's a relative trem and will depend on your hardware and pool layout etc. List your hardware config as forum rules suggest if you want further comment.
