If your laptop came with DOS as its OS, why you can see the Ubuntu installation screen?
Did you make a bootable USB for it? And what version of Ubuntu that you're trying to install, 14.04.2?

You can find the installation instructions here:

If you still have issues with it, I would suggest you to visit the community for help. Links can be found in the FAQ here.

Hi Lin,

Thanks for replying, i saw Ubuntu OEM installation screen, Because it is provided by Lenovo with Ubuntu 14.02 in thinkpad L450

But while installation it gives fatal error i.e " unable to install Grub on /dev/sda2/" .

To fix it i have tried to create partition on hdd with Ubuntu Live session (i.e. Try Ubuntu without installing), actually i have mounted /dev/sda1/ with disks utility i.e mark * to it.

which messed up booting process,now even when i am trying to boot Ubuntu 16.01 with Usb, it open initrams console.

Can you please help me to fix this ??

Sorry I got a little bit confused, so your system came with only DOS on it? Or it came with Ubuntu 14.04 (or 14.04.2?) installed on it?

Yes my system came with Pre-installed with Ubuntu 14.04 LTS OEM setup, but unfortunately i have deleted the partition.

Link :

And now after partitioning hdd, installed Ubuntu 16.01 LTS.

Actually got frustrated after not getting any support from Lenovo Support center regarding the Ubuntu OEM installation error. Then i decided to do it in my own way.

Only thing i have missed is! i didn't created the recovery disk of existing pre-installed Ubuntu OEM setup, which come with factory pre-installaton setup.

Anyways Thanks for you help.
