I know this question has been asked a lot, but I didn't find an answer here.
Ubuntu 12.04.2 64-bit was installed offline just a few hours ago on one ext4 partition, and a swap partition was also created.
The installation went fine, but now I can't get into Ubuntu.
I want to use the Windows 8 boot manager, to select between the two operating systems, so I downloaded EasyBCD and added an entry for Ubuntu.
The entry shows up in the boot manager menu, but when I click on Ubuntu I get the following message:
NST/AutoNeoGrub0.mbr not found
I tried enabling/disabling Secure Boot and restarting, but it still shows that error message.
Out of desperation I tried to find a solution myself and reset the BCD configuration via EasyBCD. Now Grub boots fine and Ubuntu too, but I can't boot Windows 8 anymore.
Then, for whatever reason after installing all updates for Ubuntu, I restarted the system and now I can't boot into Ubuntu. Only via Live CD and the old Linux entry can I start it.
