Grub problem in dual boot with windows

I have installed arch + dwm . I installed grub and updated it using

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

.
It showed :

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
Found fallback initramfs image: /boot/initramfs-linux-fallback.img
Found Windows Boot Manager on /dev/sda2@/EFI/Microsoft/Boot/bootmgfw.efi
done

But still it boots me into grub command prompt, where I get a black screen with

grub>

.
My grub.cfg : http://pastebin.com/rgbmNndM

Re: Grub problem in dual boot with windows

Which command did you use to install the GRUB loader to your disk?

What is the output of:

# parted -l

How have you mounted your partitions?

 grub-install /dev/sda

Re: Grub problem in dual boot with windows

I used :

 grub-install /dev/sda

If you have a UEFI system then that is the wrong command.

How have you mounted your partitions?

Describe in (much) greater detail the exact steps taken during installation.

Re: Grub problem in dual boot with windows

I mounted sda8 partition to /mnt and created /mnt/boot and mounted sda2 which contains efi system to it. I have also made a swap on sda9.
I installed grub using this :

grub-install --target=x86_64-efi --efi-directory=/boot/ --bootloader-id=grub --recheck

Grub installs without any errors.
When I do:
 

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

Now, I am getting this error.

That error looks informational -- the exit status appears to be zero.

Is the configuration file generated?

Does the `grub-mkconfig` command spit the file to the terminal if you run it without the "-o" flag?

You could try writing your own grub.cfg

Re: Grub problem in dual boot with windows

Yes, the grub file is generated . I tried writing my own grub.cfg . I can see the grub menu when I click F9 and then there is a grub option from many boot options, on clicking it I can boot into right OS. But it doesn't start on boot .I have to press F9 and select grub.

I don't really understand this, sorry.

It sounds like you are describing the firmware (BIOS) boot menu -- see if you can find an option to set the default boot device.
