Dual Setup with UEFI and Grub2 not properly configured

mrb101 · 2016-08-27 13:10:24

So, I have recently removed my Ubuntu system and replaced it with Archlinux in a dual boot setup along with Windows 10.
Now. I think i have missed up Grub2 configuratin as I can only get a minimal grub2 screen in which I have to point it to the Root and then insert mod linux and then load the kernal. then initrd and finally boot.
I have (/boot, /home, /) Boot, Home and Root partition

Which files from /boot is needed to help debug the problem ?

Why do you have so many partitions? :X
Is sda1 the EFISYS partition or /boot?

https://wiki.archlinux.org/index.php/GR … ation_file, perhaps?

beta990: I have so many partitions due to OEM windows. Some for recover and some for backups. Not entirly sure what they are for
Head_on_stick: Thanks for the link and i have already made the configuration file and i tried couple of different ways too.

#Here is more information

- I boot my system by doing the following
$ set root=(hd0,gpt7)
$ insmod linux
$ linux /boot/vmlinuz-linux root=/dev/sda7
$ initrd /boot/initramfs-linux.img
$ boot

# keep in mind i use autocomplete so i don't remember the exact filenames but its vmlinuz-linux or initfslinux.img

- I have boot partition which is EFI partition: sda2

I am guessing the configuration file in the EFI folder is the one i should be using. But i can't tell whats the problem

Please post the output of:

# efibootmgr -v

Please use code tags when posting terminal output and edit your post above to include these.

It looks like you have no menu entries in /boot/grub/grub.cfg

Also:

- I boot my system by doing the following

$ set root=(hd0,gpt7)
$ insmod linux
$ linux /boot/vmlinuz-linux root=/dev/sda7
$ initrd /boot/initramfs-linux.img
$ boot

That would suggest that your kernel image is located on /dev/sda7 rather than /dev/sda2 and that /boot is (or was) *not* mounted to the ESP.

Please provide full details of your installation procedure.

And to answer your second question:

I had centos first and then i installed ubuntu and used it for a while as dual boot with windows. I wanted to install archlinux again. so i installed Archlinux on the same root partition of ubuntu after formating that partition following the normal instalation steps mentioned in the documentation.

I meant that you should detail the exact commands that you used to install your Arch system.

mrb101 · 2016-08-29 19:18:42

Can I find these in a log ?
Beacause i am not sure if i remember exactly the commands i used.

$ wifi-menu --> connected to internet
$ mkfs.ext4 /dev/sda7
$ mount /dev/sda7 /mnt
$ mount /dev/sda2 /mnt/boot
$ pacstrap /mnt base
$ genfstab -U /mnt >> /mnt/etc/fstab
$ arch-chroot /mnt
$ ln -s /usr/share/zoneinfo/Asia/Kuala_Lumpur /etc/localtime
$ hwclock --systohc --utc
$ locale-gen
$ echo LANG=en_US.UTF-8 > /etc/locale.conf
$ echo each-arch > /etc/hostname

add the host name to my /etc/hosts

$ mkinitcpio -p linux

changed my password with passwd

$ pacman -S grub os-prober
$ grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=arch --boot-directory=/boot --debug
$ grub-mkconfig -o /boot/grub/grub.cfg

Note: I have used used more than one location. reinstalled and configured grub into. as the first time didn't work i tried a different time in a different location like
/boot/EFI

$ umount /mnt/boot
$ umount /mnt
$ reboot

The commands were like this.

I missed this because of the lack of code tags (that's my excuse & I'm sticking to it) -- you have no kernel image or initramfs on the EFI system partition.

You need to load up the Arch live ISO image, mount your partitions (especially the ESP) then use `arch-chroot` and re-install the linux package.

EDIT: Then reconfigure GRUB to generate the menu entries.
