I've installed Ubuntu 14.04.2 LTS on the same hard drive as my Windows 8.1 OS, on its own partition. The installation went without any hickups.
After that I used EasyBCD on my windows system to create a new boot entry for Ubuntu (Using GRUB 2).
Again, this worked fine, and starting either system via the boot menu also worked as it should.
I then let the auto-updater for Ubuntu install its updates and ever since that I cannot start Ubuntu anymore. If I try, it leaves me with this message (Right after choosing Ubuntu from the boot menu):
Try (hd0,0): NTFS5: No ang0 Try (hd0,1): NTFS5: No ang0 Try (hd0,2): Extended: Try (hd0,3): invalid or null Try (hd0,4): non-MS: skip Try (hd0,5): Extended: Try (hd0,5): EXT2:
Nothing else happens after that. Starting windows still works fine however.
I've check the partitions with the disk management utility in windows, and everything seems to be in order:
The two unnamed partitions are the /swap and root-partitions for Ubuntu.
What could be causing this sudden change? Everything was fine until I ran the autoupdater.
I've seen a similar question on here, but the problem there was with an UEFI-BIOS (Which I don't have).
