Running (only) Ubuntu 14.04 (no dual OS)

During an update, the system told me Virtual box was corrupted. It recommended I uninstall it. I did.
Then the system asked me for a reboot. I did. Now I cannot login.

1) Mouse doesn't work
2) Cursor keeps blinking at the login prompt, if I type nothing happens.
3) Then I get a msg saying connected to the network
4) The blinking cursor goes away
and I cannot interact with the machine at all.

This is my running machine which was working just fine till I rebooted.
Any suggestions?

I've had boot hang issues when I have certain USB peripherals plugged in at boot time. Unplugging them, booting and then plugging them back in solves that particular issue.

You may also be having problems with leftover (orphan) kernel support for VirtualBox.

To resolve that, you may need to boot off a rescue disc and muck with the /etc/modules config files. And/or scrape out the remnants of the kmod-VIrtualBox module.

Ok. It turned out the be a kernel issue. The problematic version was 3.13.0-45-generic

First I noticed my boot loader was gone. So I download the boot repair disk
Burnt it and rebooted on it. It presented me a very simplistic and intuitive UI where I went with the recommended option.
Reboot.
In the boot options, I first tried with the 3.13.0-45-generic(recovery mode). No luck. Same problem. Keyboard doesnt work. Mouse kaput.
Reboot.
Then I selected 3.13.0-44-generic and no problems at all.

On a related note, I tried to uninstall Virtual Box in 3.13.0-44-generic and like last time it failed.
