Upgrade From 12.04 to 14.04 restart not successful

[Coemd]

I am running a 64-bit Ubuntu 12.04 version on a virtual client being hosted on an ESXi server. During the upgrade I ensure I kept original files "default" when asked. The upgrade appeared to be complete and requested a restart to complete the upgrade. When the VM attempted a restart, it came backup to a black screen and a "static" cursor in the left corner. The machine appears to be powered on, however; I cannot get a ping response neither by IP or name and I am unable to make inputs via the console.

Any ideas?

Hi Coemd,

Reinstall GRUB:
Reboot the virtual machine with the Ubuntu 14.04 install image > Rescue a broken system >
Go through the questions that you get shown > menu 'Rescue operations': Reinstall GRUB bootloader.
This usually helps after upgrading from 12.04 to 14.04.

Thank you very much for your assistance. Reinstalling the bootloader was successful and the system was able to boot correctly and enable be to verify my upgrades.
