Hi i have a ASUS N76, recently i upgraded to win 8.1 and i wanted to install LMDE with it, when i boot on the live cd, i get from the very first shell prompting at the start error failed to gest supported dsm function, then i choose to intsall LMDE from the install mint icon on the desktop, i install it but when it shutdown after that, it ejects the cd and the screen gets freezed at the shutdown message has been broadcasted, is that normal ? When i retsart, windows runs directly and i don't have the choice of selecting mint. I have read that the hdd must be MBR to run LMDE, so with a windows utility i have deleted all the partition on the second HDD and i switched it to MBR, i created partitions on it but when i rerun the mint installation it tells me there wasn't any partition found on the sdb (my secondd hdd i switched to MBR), so i let it create table of partitions, it created a swap partition and an ext4 partition, i have divided the ext4 partition into an ext4 one (sdb2) and an ntfs one, then i chose sdb2 as the partition that will host mint with / as mount and i told grub to be installed on it, (should i have choosen sdb instead of sdb2 ?) The installation complete and the same shutdown freezing screen happens, i hit the power button to force the shutdown and at the start it's the same thing, windows boots directly. Btw i don't have the secure boot option in my BIOS. Do you know why this happens and if Mint 15 suffers from the same defaults ? Thanks fellas.
