my laptop is HP Pavilion G6-2301AX Laptop (Amd APU Quad Core A8/ 4GB/ 500GB/ Win8/ 2.5GB Graph) while installing ubuntu (multiboot) i am not able to find any partitions that i had on my windows not even the empty space that i left unassigned. the only thing i am seeing is my entire harddisk with out any partitions. previously i used ubuntu on my two other old laptops but never faced such a problem. thanks in advance.
ubuntu@ubuntu:~$ sudo parted print
Error: Could not stat device print - No such file or directory.
when i ran gparted its showing "/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?"
and i am able to see my partitions in the doc on the left side
