[SOLVED]/vmlinuz-linux not found

Hi there! It's my first time installing Arch and i'm having trouble on the first boot, after installing.
I tried reinstalling 3 times, following carefuly the steps of Arch's instalation guide, but always ended up having the same result:

When I finish installing the packages with packstrap, I install GRUB, unmount, reboot and i always end up with the grub prompt " GRUB> " If I try to pass boot It will tell me that first i need to load the kernel
I've tried searching online how to solve this, and tried (if I don't recall badly):

grub> insmod linux
grub> linux /boot/vmlinuz-linux root=/dev/sda5

and got as a result '/vmlinuz-linux' not found

The steps i took regarding GRUB install were(other steps were taking in between, but i'll only explain the ones i feel related to GRUB, please ask if needed):

* i've set up a fat 32 partition for boot, as stated on the installation guide (500mb size), with the following command
# mkfs.fat -F 32 /dev/sda6

*then # mount --mkdir /dev/sda6 /mnt/boot

*i downloaded the needed packages with pacman: grub, grub-install, efibootmgr, grub-mkconfig

*installed grub using grub-install with the command grub-install --target=x86_64-efi --efi-directory=/boot ==bootloader-id=GRUB (i can't remember if it was --efi-directory=/boot or --efi-directory=/boot/efi. either way, one of those worked and let me install grub, the other didn't

If more info is needed, please let me know!
Thanks for reading this topic (L)

Re: [SOLVED]/vmlinuz-linux not found

Did you chroot after the mount? Also the device node you mention as having created the FAT FS on sda6 and the device you're actually mounting to /boot sda5 don't match in this excerpt of yours.

I'd say to assess the situation, boot into the live system, mount the partitions like you think they are correct, do a chroot and post the outputs of

mount
lsblk -f 
pacman -Q linux
ls -l /boot

you can use https://wiki.archlinux.org/title/List_o … n_services to paste from the cmdline assuming you can set up a network connection.

Sorry! That was a typo.I mounted /dev/sda6 to /mnt/boot, then I did chroot

On the GRUB prompt i typed grub> linux /boot/vmlinuz-linux root=/dev/sda5 because i tought that I had to target the root partition, is that ok?

I'll do what you ask and come back

Thanks!

Re: [SOLVED]/vmlinuz-linux not found

It depends on what you installed where. If you indeed made a separate VFAT partition that you mounted to /boot and installed grub as well as the kernel there, the correct grub lines would be

linux /vmlinuz-linux root=/dev/sda5 
initrd /initramfs-linux.img

since the paths need to be relative to the root of the partition which would be /vmlinuz-linux directly (without the /boot, since that's part of the root partition but you're booting from the VFAT partition directly)

FWIW symptoms sound like you might simply have forgotten to run grub-mkconfig -o /boot/grub/grub.cfg to generate a menu entry.

I was about to post the output of the console, but then I've read your reply and try to run grub-mkconfig. I think that when i was finishing the install i havent executed that command properly, and my imput was just "grub-mkconfig" ??

Now is working! Thank you so much!
