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

I was following the installation wiki however when i tried to boot from the usb i got dropped into normal shell. I tried following this but this is what i got

grub> insmod fat
grub> set root=(hd0,msdos1)
grub> chainloader (${root}/EFI/Microsoft/Boot/boot/mgfw.efi)
error: can't find command 'chainloader (hd0,msdo'.

the output of "set" command is:

?='0'
color_highlight='black/light-grey'
color_normal='light-gray/black'
feature_200_final='y'
feature_chainloader_bpb='y'
feature_default_font_path='y'
feature_menuentry_id='y'
feature_menuentry_options='y'
feature_nativedisk_cmd='y'
feature_ntldr='y'
feature_platform_search_hint='y'
feature_timeout_style='y'
grub_cpu='x86_64'
grub_platform='efi'
lang=''
locale_dir=''
net_default_ip=''
net_default_mac=''
net_default_server=''
pager=''
prefix='(memdisk)/boot/grub'
pxe_default_server=''
root='hd0,msdos1'
secondary_locale_dir=''

for some further context. After i got this error i tried to boot the usb on another computer that had mint/windows double boot and it worked just fine, the machine encountering the problem is running ubuntu

Also just a general question, would it be a good idea if i were to use cfdisk to remove all old partitions and then make new ones or would that be a bad idea? (i want a completely clean slate for my install)

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

What do you want?
- actually installing ArchLinux onto an USB pen?
or
- boot the ArchLinux Live USB?

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

yes i read that and used rufus to format my live usb. I know that the way i formatted the usb is correct because it booted alright (by alright i mean that i could continue the installation) on my other computer which was running mint/windows double boot

yes it works correctly on the other computer but not on the one i intend to install arch on. which means something else is broken

Ah, oh, OK! Well... Are you actually booting your PC from the ArchLinux Live USB? Are you trying to boot in pure UEFI mode? Or there's some CSM going on? Is the ArchLinux's Start Screen appearing?

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

yes im booting from the archlinx live usb in uefi mode and once it boots i get dropped into grub "normal" shell, there are no error messages or anything, just a prompt to enter commands into
there is no option to enable CSM in my bios so i dont think its enabled

I tried following this

Still, I don't get how this should be related to ArchLinux' USB actually booting! hmm
Why do you want to chainload Windows' .efi Loader? it has nothing to do with booting ArchLinux USB...
</EDIT>


Can you please boot into Ubuntu and try creating (again) the ArchLinux Live USB? But this time please use one of the Linux CLI methods as reported here: https://wiki.archlinux.org/title/USB_fl … _utilities

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

ok i used the cat method and got the same result (dropped into grub "normal" shell, there are no error messages or anything, just a prompt to enter commands into)

the reason why i tried the chainloading solution is because it was the closest thing i found to solution and figured i might as well try it

Solution to what, precisely? Chainloading Windows' .efi Loader from GRUB will simply get you to boot into Windows... I don't see how this "solution" could lead you to boot ArchLinux's Live USB.

Anyway...

Does creating others Linux USB Live System(s) get your computer actually booting into a Live Environmet just fine?

What ArchLinux's ISO did you download? Did you verify its Chechsums?

Within Ubuntu, insert your ArchLinux's Live USB and post here:

$ sudo gdisk -l /dev/YOUR_USB_IDENTIFIER
### eg.: $ sudo gdisk -l /dev/sdb ###

Can you please post here a photo of your computer's screen when you're in the UEFI's Boot Menu?
(please paste here the link to the uploaded image, not the image itself!)

Someone please correct me, but afaik ArchISO doesn't even use grub.
This "normal shell" doesn't say something like "root #" by any chance?

Yup. In fact, I'm trying to understand what's going on with vrik computer... If the ArchLinux's USB fail, that should proceed with starting Ubuntu's GRUB (which could be confirmed by i used the cat method) But... Did he actually boot into Ubuntu? Or USER is using the other computer (Linux Mint)?


@vrik:

  • Computer A has Ubuntu installed, right? Is Ubuntu the only OS on A?

  • Computer B is Dual Boot: Linux Mint + Windows. Did I understand correctly?

  • Which one fails booting ArchLinux's USB? Computer A or B?

  • grub> chainloader (${root}/EFI/Microsoft/Boot/boot/mgfw.efi)

    on which computer did you try this?

It uses GRUB for UEFI booting but syslinux otherwise.

@OP: are you sure you selected the USB stick from the motherboard firmware ("BIOS") boot menu?

Do these commands get the ISO loading (reboot first to clear your earlier attempts):

cmdpath='(cd0)/EFI/BOOT'
config_directory='(memdisk)/boot/grub'
config_file='(memdisk)/boot/grub/grub.cfg'
default='archlinux'
root='memdisk'
normal

Found valid MBR and GPT. Which do you want to use?
 1 - MBR

 3 - create blank GPT

But on A there's Ubuntu only and still you tried chainloading a non-existing OS (Windows).

Well... There's something wrong with your USB stick (or with your computer's UEFI implementation).

i tested the mint liveusb on the mint+windows double boot and it worked, which means that UEFI implementation must be broken

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

What if you remove... Let's say... 7th entry???
Boot into Ubuntu and go with

$ sudo efibootmgr -B -b 0006

$ sudo efibootmgr -u

Take note of 2nd command's output, reboot and tell us what happened.

If ArchLinux's USB still fails to successfully boot, then paste here the output from 2nd output as said above.

Let's see if 0006 entry has been re-created by UEFI's Firmware: boot again into Ubuntu and check if there's still Boot0006* Floppy Disk Drive: or not by using

$ sudo efibootmgr -u

WARNING!!!
IF YOU'RE UNSURE ASK HERE FIRST BEFORE PROCEEDING!!!

WARNING!!!
Try deleting more and more entries as you go.
At some point you maybe end up successfully booting the ArchLinux's USB (I hope).
