I have a asus s56 with preloaded Windows 8 and I've recently upgraded to Windows 8.1.
During the installation of Xubuntu I've selected custom partitioning (something else):
I've formatted in ext4 a partition and I've there the root, I've selected another empty partition for swap and then I've put the xubuntu bootloader in the first, cause I've read that for some reasons it's better to leave boot operations to windows leaving the system MBR intact, and then to insert an entry in the win boot manager.
After installing Xubuntu, I've managed to insert the entry from Windows with EasyBCD: I've choosen Grub2. Restarting the pc the blue screen to select the os appears: If I choose Windows it starts perfectly, if I choose Xubuntu Windows boot manager reports error and doesn't boot Xubuntu.
What can I do?
