laptop problems

[arelem3]

I have  Dell 1520 laptop which had Fedora20  and ubuntu 14.04.
The cdrom is inoperable so any installation has to be usb which to now 
was no problem.
I have 14.04LTS live on the usb and have used it to install ubuntu 
previously on this and other machines.
Both Fedora and Ubuntu started reporting low disk space for root /.

I deleted an empty partition on the laptop using gparted from Fedora and 
now the computer will not boot.

Ubuntu 14.04 will not provide the manual hard drive formatting options 
and partition creation system I am accustomed to with Fedora and CentOS.
I tried to do a fresh install of 14.04 from the usb but get an error: 
Kernel Panic - not syncing: VFS: Unable to mount root on unknown-block(0,0)
  If I boot without the usb stick live 14.04 I get error: no such 
partition. Entering rescue mode.

<grub rescue> If I do ls I get (hd0) (hd0,msdos5) (hd0,msdos3) 
(hd0,msdos3) (hd0,msdos1)
ls (hd0,msdos5) does nothing.
  I want to install 14.04LTS again but cannot get to manual partitioning.

Can someone please help
Thanks in advance
Roger
