I have tried to install Ubuntu alongside my windows 8 but when I run the installer, in my bootable flash the installer does not recognize my windows partitions. It shows my hard drive as one unallocated 500GB. I researched and someone had a similar problem and he was instructed to run the following command
sudo fdisk -lu inside the Ubuntu installer. From his output he was told that some of drives are overlapping. I have run the same command in my installer and this is my output:
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

I have used this same Ubuntu installer on my friends machine and it works well. I have even tried to install mint from a DVD and i get the same problem.
When I run the command above in both installers I get the same output.
When I run another command
sudo gparted -l i get the following output.
Warning: /dev/sda contains GPT signatures
indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No?
