Dual Boot doesn't work - Win8.1 - Acer E5-571G.

theodoiq · 2015-07-29 19:46:15

Hi,

After fresh install and 2 hole days searching solutions, I can't boot archlinux in a machine with pre-installed Win8.1.

All bootctl, refind-efi, gummiboot fails. When I reboot... just are Windows Boot Manager loading Windows automatically.

I didn't find any topic related with this particular hardware, an Acer E5-571G

Disk are parted with GPT.

This is my situation on partitions:

lsblk /dev/sda
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 600M 0 part
├─sda2 8:2 0 300M 0 part
├─sda3 8:3 0 128M 0 part
├─sda4 8:4 0 851.7G 0 part
├─sda5 8:5 0 18.8G 0 part
├─sda6 8:6 0 25G 0 part /mnt
├─sda7 8:7 0 512M 0 part /mnt/boot
├─sda8 8:8 0 32.5G 0 part /mnt/home
└─sda9 8:9 0 2G 0 part [SWAP]

Ever mounting swap - /mnt - /mnt/boot - /mnt/home, on this right order.

Device "sda7" is set to boot, formated in fat32.

Installation made after boot in UEFI mode.

This is my "df -h" after arch-chroot:

Filesystem Size Used Avail Use% Mounted on
/dev/sda6 25G 6.1G 18G 26% /
/dev/sda7 511M 88M 424M 18% /boot

tmp 3.9G 0 3.9G 0% /tmp
/dev/mapper/arch_airootfs 32G 823M 31G 3% /etc/resolv.conf

My mount after arch-chroot:

Could someone give me some help?

Thanks in advance!!

Have you tried disabling Secure Boot (and fast boot) from your firmware (BIOS) options?

What is the output of:

# efibootmgr -v

Of course.

This is my efibootmgr

Post the exact commands that you used to install these.

What was the exact terminal output when you used those commands?

There are no NVRAM entries for your Arch system so it is no surprise that it does not boot.

Load up the Arch live ISO, mount all of your partitions, use `arch-chroot` then post the output of:

lsblk -f
# gdisk -l /dev/sda

Just to note: you should share the EFI system partition generated by Windows with your Arch system rather than create a new one.

If you create a custom NVRAM entry, does this boot:

# efibootmgr -d /dev/sda -p 7 -c -L "Arch" -l /vmlinuz-linux -u "root=/dev/sda6 rw initrd=/initramfs-linux.img"

When I install Arch and Windows together, I make sure both are using the same EFI partition which for me is usually /dev/sda1. In the past (not sure if that's the case now), if Windows detects it isn't the primary boot, it will change that. This makes any other boot loader be secondary to Windows.

To change this, I trick Windows into thinking grub (I use grub on my machines) is the Windows boot loader and save the Windows boot loader as a new separate file. Then I tell grub where the new Windows boot loader file is and have it chain load when I need to use Windows. I did this yesterday in fact because I upgraded to Windows 10.

If you would like more instruction on how this is done, I can elaborate further.

Try installing grub again, if you already have arch installed then mount the partition with the following:

mount /dev/sdaX /mnt

then make a directory for the efi boot partition to be mounted

mkdir -p /mnt/boot/efi

then mount the efi partition to the new directory

mount /dev/sdaX /mnt/boot/efi

then chroot into /mnt

arch-chroot /mnt

get grub

 pacman -Syu grub

get efibootmgr

 pacman -Syu efibootmgr

generate a grub config

grub-mkconfig -o /boot/grub/grub.cfg

now install grub to sda

grub-install /dev/sda

Now grub should be installed and you shouldn't have received any errors. This will only show your arch install on grub to start once your booted into arch you need to install os-prober with pacman. After you installed that you can run:

grub-mkconfig -o /boot/grub/grub.cfg

Now grub should be installed and your system should show arch linux and your windows 8 partition as well. Now if you did receive an error doing this and grub did not install, you need to enable UEFI boot and create UEFI bootable usb and re run the commands given. I found it easier to use a program called rufus to create it. I use rufus to write ubuntu to the drive. After doing this I would edit the grub config file to allow me to also boot straight from a arch iso by adding:

menuentry 'Arch Linux' {
    set iso="/boot/iso/archlinux-2015.05.01-dual.iso"
    loopback loop $iso
    set root=(loop)
    linux /arch/boot/x86_64/vmlinuz archisolabel=ARCH_201505 img_dev=/dev/disk/by-label/MULTI img_loop=$iso earlymodules=loop
    initrd /arch/boot/x86_64/archiso.img
}

to my grub config file on my usb. Then right click on the drive go to properties and rename it to "MULTI".

Then you need to go back in to the usb drive open your boot folder create a new folder called "iso" copy your arch iso to this new folder.

This will make it so you can boot strait into the arch iso in UEFI mode and not CMS. You may have to press F12 to select it on boot but it should work. I hope this helps.
