First of all I'm new to Ubuntu. First time i saw Ubuntu on my sis Laptop. I upgraded my sister's Laptop, its not working after upgrading from Ubuntu 14.04 to 16.04.
Now only blank pink colour is showing and caps lock is blinking.
There's an option showing in GURB to restore to 14.04, but it'll wipe all files which i don't want(Yes i able access to GURB by pressing Shift Key).
These are the cmd which i used in terminal.
sudo apt update sudo apt dist-upgrade cat /etc/lsb-release sudo do-release-upgrade -d
While upgrading, 3-4 times a option like this came(xxx= some name was there which i forgot) in which i pressed Y.
Configuration file '/etc/xxx/xxxx.xxx' ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. *** Xxx.xxx (Y/I/N/O/D/Z) [default=N] ?
This option also came, it ask me to put some password.
Your system has UEFI Secure Boot enabled. UEFI Secure Boot is not compatible with the use of third-party drivers. (...) Ubuntu will still be able to boot on your system but these third party drivers will not be available for your hardware. Disable UEFI Secure Boot? (yes | no)
