Grub is not showing Arch Linux.

Hi!

I'm trying to install "archlinux-2020.01.01-x86_64.iso", but after install the system GRUB is not finding Arch, only Windows.

The output of fdisk -l (the "..." was edited by me):

fdisk -l
Disk /dev/sda: 465.78 Gib, ... bytes, ... sectors
Device        Boot    Start   End  Sectors  Size  Id   Type

/dev/sda7                ...      ...        ...         ...    82  Linux swap / Solaris

Disk /dev/sdb: 1.91 Gib, ...bytes, ... sectors (arch linux iso flashdrive)

fstab:

# <file system> <dir> <type> <options> <dump> <pass>

# /dev/sda7
UUID=26930bb7-132f-4ab8-ab9e-bcd5e4d07d4  none  swap  defaults  0  0

After install "grub-bios" and "os-prober" I tried the following commands:

grub-install --target=i386-pc --recheck /dev/sda
grub-mkconfig -o /boot/grub/grub.cfg

Generating grub configuration file...
grub-probe: error: cannot find a GRUB drive for /dev/sdb1. Check your device.map.
Found Windows 7 on /dev/sda1
done

How can I fix this problem?

Re: Grub is not showing Arch Linux.

Please use code tags rather than quote tags when posting terminal output.

I think we need more details about your installation procedure. And the full grub.cfg (or the output of the plain grub-mkconfig command).

Re: Grub is not showing Arch Linux.

Well, regarding only the partitions I'm doing this:
(right after the flashdrive boot and I did not post the wifi configuration for instance and other things because is not important, I think)

mkswap /dev/sda7
swapon /dev/sda7

mkfs.ext4 /dev/sda5
mount /dev/sda5 /mnt

mkdir /mnt/media
mkdir /mnt/media/backup
mkdir /mnt/media/flashdrive
mkdir /mnt/media/windows

mount /dev/sda6 /mnt/media/backup
mount /dev/sda2 /mnt/media/windows

genfstab -U -p /mnt >> /mnt/etc/fstab

arch-chroot /mnt

pacman -S linux-headers mesa xf86-video-ati xf86-video-vesa dialog wpa_supplicant os-prober

mkinitcpio -p linux
grub-install --target=i386-pc --recheck /dev/sda
grub-mkconfig -o /boot/grub/grub.cfg

Re: Grub is not showing Arch Linux.

Have you installed a kernel?

Re: Grub is not showing Arch Linux.

No, I didn't install all with pacstrap, only:

pacstrap /mnt base base-devel grub-bios exfat-utils ntfs-3g

The others I did with pacman like in post #3.
As you can see in the original post /dev/sda1 is setted as bootable. I was wondering if I use cfdisk to set the /dev/sda5(Linux) as bootable too. Do I have to install all the system again after do this or is just save and exit?

Re: Grub is not showing Arch Linux.

Read the link that 2ManyDogs posted again  - and actually read it this time.


No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
