Please post the output of this command from the problematic machine:

Sorry OP, I forgot that Ubuntu's options are different. I wanted to see the actual EFI loaders so I think we need

efibootmgr -uv

And please use code tags rather than quote tags when posting terminal output. Use the Edit button on your posts to change this, it will make the thread more readable. Thanks.

I really don't think randomly deleting boot entries is helpful. We could end up bricking the OP's machine.

Re: Booting from a arch liveusb drops me into grub normal shell [SOLVED]

Your first post doesn't show cmdpath in the output, but it's used by the embeded grub.cfg to load the grub.cfg on the ISO.

First things, first. Confirm whether this is even the correct GRUB you're launching. Run:

cat (memdisk)/boot/grub/grub.cfg

and see if it matches https://gitlab.archlinux.org/archlinux/ … #L588-L595 .

It it matches, try:

configfile (cd0)/EFI/BOOT/grub.cfg

(cd0) may need to be (cd1), (cd2), etc., run ls to see which devices are available.

the output of ls is

(memdisk) (hd0) (hd0,msdos1) (hd1) (hd1,gpt3) (hd1,gpt1) (cd0) 

so i went with cd0, and it just cleared the console and when doing ls again there was a new device called (proc)

Re: Booting from a arch liveusb drops me into grub normal shell [SOLVED]

And (cd0)/EFI/BOOT/grub.cfg matches https://gitlab.archlinux.org/archlinux/ … b/grub.cfg , right?

Best I can suggest is creating the installation medium using https://wiki.archlinux.org/title/USB_fl … NU/Linux_4 and editing EFI/BOOT/grub.cfg on it. E.g. trying to comment out "terminal_output gfxterm" or some other line and see if it helps or not.

Or just try typing out the grub.cfg line-by-line and see where it goes wrong.

Re: Booting from a arch liveusb drops me into grub normal shell [SOLVED]

Just to confirm, when you first get dumped in the GRUB shell, there's no cmdpath in the output of set, right?

And just for curiosity, what was the correct device name for you?

it was (hd0,msdos2), i knew what device it was using a very primitive method of ls > unplugging the usb > ls > checking whats missing

nl6720 wrote:

now that its fixed there is no way for me to check it, though in my initial post i gave the output of set and there seems to be nothing related to cmdpath (could have been a error on my end because i had no way to copy the output so i wrote the output by hand)
