Ubuntu.. missing after upgrade!!
« on: August 20, 2016, 08:28:42 am »
Hi have been running Ubuntu along side Windows 7 for some time which has been a pleasure to use compared with Windows. Prompted with an upgrade instruction I commenced to download the files and start the upgrade process which seemed to take some time. However when I start ubuntu a long list of instruction code appears showing (ok) ------ accept to the point of 'starting to show plymouth boot screen' statement appears followed by the flashing cursor and then nothing!! i.e. no key board intervention has any effect and my lap top just hangs in this state. I have to shut down completely. Any ideas on this or do I have to reload Ubuntu from scratch?

Does hitting Ctrl+Alt+f2 when you're at the flashing cursor drop you to a text console ?

Hi Mark.. thanks for reply. Ctrl+Alt+F2 asks me to login but doesn't accept login password? just returns login detail incorrect?

It'll likely be that you have a strange key repeat on when typing in a console, I have to be very positive with keystrokes, not stay on the key for too long, and leave a second or so between keystrokes when entering my password in a console.

Try again and let me know.

I feel I have embarassed myself with this problem. I'ts the Login that's not being accepted which has to be correct before entering a password
and that's what I have trouble with! My login is showing incorrect..I have not changed it at any time so can't get passed this first hurdle so can't log in?

try login as an admin. user name is: root
and the password would be the default one whatever your distribution has or whatever you have changed it to.
after that just change what you need or even create the new user and delete the old one ;)

Hi Sneaky Tommy... tried what you suggested but no difference. Still shows login incorrect_basically after entering login and hit return
password request will not allow any characters input. If I then press return the next line shows login incorrect!

Even when you select the "Guest" account ?

Have you got an Ubuntu LiveDVD/LiveUSB ?

If so, boot to it and post the output from
Code: [Select]
sudo fdisk -l
and
Code: [Select]
sudo blkid

Hi Mark   This is the situation. Windows7 dual boot_Ubuntu first boot option all working fine until upgrade message appeared and from then on all went wrong. First option Ubuntu in boot up now results in a blank screen and hangs. Next option advanced settings selecting Ubuntu with Linux (recovery mode) when generic is selected a scrolling screen of data results and terminates with the request to login:
Ubuntu 16.04.1 LTS penndrow-xxxxxx-xxxx tty1
penndrow-xxxxxx- xxxx login: _
