I installed Ubuntu 14.04 (Trusty Tahr) along with Windows 8. When I install it I give it just a 7 GB partition. After five days the Ubuntu partition is completely full (low space).

So I just booted into Windows 8 and deleted the Ubuntu partition and created a 40 GB partition for Ubuntu. When I restarted the PC to install Ubuntu 14.04 on that partition again, I got this message:

error no such partition grub rescue

I am getting this type of message on every boot. Now I am not able to boot into Windows or Ubuntu. Why?

This has happened after deleting the Ubuntu old partition. I don't know what to do now. I don't have any CD ROM in my PC.

How should I proceed to install Ubuntu again?

When you installed Ubuntu after Windows 8, you also installed the GRUB bootloader which is handled by the Ubuntu GRUB manager which lets you select which operating system to boot. In your case, either Windows or Ubuntu. When you restarted your computer after deleting the Ubuntu partition it is searching for GRUB, but you deleted it. That is why the problem is occurring.

Solutions:

  1. As your PC don't have a CD-ROM drive, you can make an Ubuntu bootable USB pendrive by burning the ISO image file of Ubuntu on to the pendrive (as your PC is not working, you have to use another PC). Then install Ubuntu again on that 40 GB partition with that pendrive. Therefore you can see your Windows and Ubuntu again.
  2. If you don't want to install Ubuntu, then the most straightforward solution is installing Windows again. As you don't have a CD-ROM drive you can follow solution 1 to install Windows using a pendrive.

When you deleted your Ubuntu partition, you also chucked out your GRUB installation. GRUB is the bootloader for your machine which lets you boot into either Ubuntu, Windows, or any other present OS.

To boot back into Windows, you should be able to interrupt your boot and enter the UEFI by pressing one of the following common keys after powering on: F1 F2 F10 F11 or ESC. Which one works will depend on your laptop's make and manufacturer.

Once in UEFI mode, navigate to your boot options and move Windows Boot Manager back to the top of the list. Saving your changes and rebooting your computer should result in loading Windows. Once in Windows, download an Ubuntu 14.04 ISO and burn it to a USB drive using the tool of your choice.

Shut down your computer and turn it back on, then select the Ubuntu Live USB as a temporary boot device (press F12 typically at boot, or reorder your boot devices in UEFI). Follow the instructions for a dual boot system presented at the install screen.

Use the Ubuntu live CD and then use the GParted partition editor to set the boot flag to your Windows partition. (Right click on the Windows partition -> Manage flags -> Boot). This will let you boot Windows (like having a single Windows OS).

Afterwards, install Ubuntu again (as you did before to get a dual-boot system), this time using the bigger space.
