1st problem: I have accidentally erased my boot folder. Now I'm stuck with grub in rescue mode, as I am unable to find /boot to satisfy grub.

2d problem: I tried to boot from a live distro (I tried several ones) but all I got is a black screen with a blinking cursor… So impossible to access to a terminal

I don't have any CD/DVD reader on my laptop but I was able to install xubuntu 14 (64bit) from an USB stick in the past (the first time I install xubuntu, before I deleted /boot…). And of course I have no other partition on my laptop, so all I can do is stare at this nice grub rescue mode… (So I have no access to a terminal)

In this day I'm just desperate… If somebody have a clue of what is going on it will save my shitty week!

You should create a new live-usb with Xubuntu 64 bits or some derivative of Debian 64 bits and try this:

Step 1: Boot into Ubuntu Live-Usb

Step 2: Open a terminal,

Press Ctrl+Alt+T

Step 3: Login as user with administrator permissions.

sudo -i

Step 4: Find out how your partition / is called with fdisk.

fdisk -l

Step 5: Suppose it is /dev/sda1, mount the partition in /mnt, previous fsck

umount /dev/sda1
fsck -a /dev/sda1
mount /dev/sda1 /mnt

Step 6: Mount the following paths in the respective locations in the /mnt namely – /dev, /sys, proc, and devpts.

mount -o bind /proc /mnt/proc
mount -o bind /dev /mnt/dev
mount -o bind /sys /mnt/sys
mount -o bind /dev/pts /mnt/dev/pts

Step 7: chroot into the Ubuntu partition

chroot /mnt

Step 8: Create /boot folder an instal linux kernel and Grub2

mkdir /boot
apt-get update
apt-get install --reinstall linux-headers-3.13.0-83 linux-headers-3.13.0-83-generic linux-image-3.13.0-83-generic linux-image-extra-3.13.0-83-generic grub-common grub-pc grub-pc-bin grub2-common
grub2-install --root-directory=/mnt /dev/sda

Step 9: Un-mount the previously mounted directories and reboot.

umount /mnt/proc
umount /mnt/dev/pts
umount /mnt/sys
umount /mnt/dev
umount /mnt
reboot
