Dualboot Arch and Window 10 (uefi)

bhanu · 2016-03-05 15:16:26

Hello,

I tried to dual boot windows 10 and arch with boot loader on usb but something gone bad and i was unable to boot into windows also in arch a message popped up something is wrong i have to click logout.

I have windows installed on uefi mode on disk, here is the details of the disk:
/dev/sda
/dev/sda1
/dev/sda2 (EFI partion)
/dev/sda3
/dev/sda4 (windows C drive)
/dev/sda5 ( D drive)
/dev/sda6 ( E drive)
/dev/sda7 ( for swap)
/dev/sda8 (for arch )

/dev/sdb (pendrive)

Steps what i have done :

1. i boot using archiso disk
2. created swap and partition for arch which is in ext4 format i have done this using "cfdisk"
3. swapon /dev/sda7 //turned swapon
4. mkfs.ext4 -L "Arch Linux" /dev/sda8 //formatting partition for linux
5. mount /dev/sda8 /mnt //mount the partition or linux

6. pacstap /mnt base //installed base system

******************************************************************************************
7. mkdir -p /mnt/boot/efi
mount /dev/sda2 /mnt/boot efi //mount efi filesystem
*********************************************************************************************

8. genfstab -p /mnt >> /mnt/etc/fstab //generate fstab
9. arch-chroot /mnt //chroot into arch installation
10. passwd root // changing password
11. ln -s /usr/share/zoneinfo/Asia/Kolkata /etc/localtime //set timezone
12. mkinitcpio -p linux //generate initial ram disk
13. pacman -Syu grub efibootmgr
pacman -Syu efibootmgr

*****************************************************************************************************
14. grub-mkconfig -o /boot/grub/grub.cfg //generate grub configuration
15. grub-install /dev/sdb //install grub into pendrive
****************************************************************************************************

16. pacman -Syu gnome-desktop //install desktop environment
17. useradd -G wheel -s /bin/bash -m -c "Bhanu Sharma" bhanu //add user
18. passwd bhanu // set password
19. pacman -Syu xterm vim
20. pacman -Syu gdm //gnome desktop environment
21. systemctl enable gdm //enable gdm to start on boot
22. exit
23. umount -R /mnt
24. reboot

// i think commands inside the ****(s) have gone bad

With ubuntu it is so simple i just have to select the pendrive for installation of bootloader from dropdown menu

So if anyone can help me what i have done wrong,and how to do it correctly
i will be trying again tommorow

Under point 7, you created a boot/efi dir, where is your backslash between "boot efi" when you are mounting it?

It should read:

mount /dev/sda2 /mnt/boot/efi

Please explain this a bit more.

Do you mean that you want the system to only boot with the USB stick plugged in?

I'm not even sure if this is possible with a UEFI system without some workarounds.

That is very vague.

Please provide a more detailed description and the actual error message.

See https://bbs.archlinux.org/viewtopic.php?id=57855

Which guide are you following?

The Beginner's Guide recommends mounting /boot to the ESP.

EDIT: Also, typo, as noted above.

That `grub-install` command is incorrect.

You need to follow https://wiki.archlinux.org/index.php/Beginners'_guide, https://wiki.archlinux.org/index.php/GRUB#UEFI_systems & https://wiki.archlinux.org/index.php/Du … th_Windows

6. pacstap /mnt base //installed base system

Another typo, I hope you actually typed pacstrap

Besides, it helps to also get base-devel, which is needed to get sudo working and install AUR packages:

6. pacstrap -i /mnt base base-devel

You have to change your mindset, Arch is unlike most other distros, just follow the Beginners Guide line-by-line. You will learn a lot and you will have a lean system with the latest packages.

Thanks vignvig, kirkx and Head_on_Stick(thank you so much for such a detailed ans) for reply

I again tried today and dropped the idea of booting from pendrive and followed beginners guide
so i used bootctl instead of grub
Here is the command and output:

#mount /dev/sda2 /boot

#bootctl install

Created "/boot/EFI/systemd".
Created "boot/loder".
Created "/boot/loader/entries".
Copied "/usr/lib/systemd/boot/efi/systemd-bootx64.efi" to "/boot/EFI/systemd/systemd-bootx64.efi".
Copied "/usr/lib/systemd/boot/efi/systemd-bootx64.efi" to "/boot/EFI/Boot/BOOTX64.EFI"
Created EFI boot entry "Linux Boot Manager".

BUT Still i was not able to boot to linux

When i start the computer a promt shows having 3 entries
Window Boot Manager //when i click it i boot into windows
EFI Default Loader //when i click it a promt appear with 2 entries(Window Boot Manager and Reboot into Firmware Interface)
Reboot into firmware interface //goes into BIOS

there is no entry to boot into arch
So what to do, to boot into arch and how to get its entry here

That's just a directory.

You need to write the configuration file for the menu entry as well ("arch.conf", or so).

See https://wiki.archlinux.org/index.php/Sy … ot_entries

EDIT: The "EFI Default Loader" is the boot entry that will load systemd-boot (via /boot/EFI/BOOT/BOOTX64.EFI).

I created this file at /boot/loader/entries/arch.conf and write it as
tile Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linuz.img
options root=PARTUUID=d53cb93e-9b21-4cbc-b6cc-468abc06c8b0 rw

I write this file as according to https://wiki.archlinux.org/index.php/Sy … ot_entries

I also do run this command

#efibootmgr -c -d /dev/sda -p 8 -l /EFI/systemd/systemd-bootx64.efi -L "linux Boot Manager"

and now i getting the error :

Error Loading \vmlinuz-linux: Not Found
Failed to execute Arch Linux (\vmlinuz-linux): Not Found

After that i boot into windows so what to do now

You should use -p 2 instead -- that flag points to the EFI system partition number, you have used the root partition number.

Does the "EFI Default Loader" boot entry work?

Check if vmlinuz-linux is actually present on /dev/sda2

when you did the partitioning you did make sda2 bootable?
set 2 boot on

EFI system partitions should already be flagged as "boot, esp" in parted & gparted so that is not needed

Thanks Head_on_a_Stick,

well i able able to dual-boot both OS
This time i used "rEFInd"
Still there are some glitches like D and E drives and not auto-mounting(have entry for them in /etc/fstab) and have many entries in "reEFInd menu" like one for grub, one for systemd

I think i should re-partition my disk again, install windows and then arch and hopefully not make mistakes.

Arch Linux
