This question already has an answer here:
I got a new ACER predator AG3620-UR308 which came with windows 8 and I wanted to run ubuntu 12.04.2 on it as a dual boot machine. The box came with 2TB HDD. So I made 4 partitions with a raw partition just after the windows installation partition.
I created a swap area and finished the installation. GRUB was installed on the only drive there which is
After reboot, GRUB doesn't even come up. It always boots Windows 8. I repeated installation process twice and got the same result. I disabled
secure boot from the BIOS and enabled
CSM (don't even know what it means) according to Acer custhelp site . I boot from USB and got this:
$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Can anybody shed some light? thank you in advance
I just did another trial with 13.04 this time and still no luck.
bios: secure-boot: disabled enable CSM : always
- Deleted previous Ubuntu partition and swap area partition.now having free space
- Used usb installer to prepare usb with ubuntu-13.04-desktop-amd64.iso
- rebooted : liveusb didnt detect windows 8, used something else
- created partition ext4 for
- created partition for swap-area
- default grub path is
/dev/sdaand clicked install
Acer always boots into windows.
After following the boot-repair suggestion installed on the liveUSB, I can now see grub but can't log into windows anymore as it's not in the list. The boot-repair also completed with an error, i guess logged on pastin.ubuntu
How my drive is organized
