Comment 39 for bug 1381170

ok everything went fine as too using

sudo mkdir /target
sudo bash
mount /dev/md126p5 /target
cd /target
mount -t proc proc proc/
mount -t sysfs sys sys/
mount -o bind /dev dev/
cp /etc/resolv.conf /target/etc/
chroot .
apt-get mdadm grub2

I should have copied the first time, the output. I am sorry I didn't. But windows still boots up. No grub menu or anything.

But I went to reconfigure grub again but this is the end result.

ubuntu@ubuntu:~$ sudo mkdir /target
