After arch re-install, windows from grub gone ?

Utini · 2015-10-31 23:08:46

Hey there, I had a dual boot setup with windows 8.1 + arch using grub as bootloader. Everything was fine until I re-installed arch (including grub), since then the windows entry is missing from grub ?

I basically did everything as the wiki says. Those are the commands I used:

#Mount EFI Partition
mkdir -p /mnt/boot/efi
gdisk -l /dev/sda # output -> #1 = EFI boot partition
mount /dev/sda1 /mnt/boot/efi

#generate fstab
genfstab -p /mnt >> /mnt/etc/fstab
cat /mnt/etc/fstab

.
.
.

#generate RAM Disk
mkinitcpio -p linux

#install bootloader
pacman -Syu grub efibootmgr

#generate grub config
grub-mkconfig -o /boot/grub/grub.cfg

#install grub altough it is already installed?
grub-install /dev/sda
ls -l /boot/efi/EFI/arch # -> output = grub ?

Any ideas what went wrong and how to fix it?

Thanks !

Not an Installation issue, moving to NC...

Install os-prober, then recreate your grub.cfg.

Looks like os-prober did the job, I can't remember if I installed it for my first Arch setup Thanks !
