Before downvote, please this is not a duplicate I read the related questions and couldn't solve my problem.
I bought a new laptop that originally had Win8 installed, I formatted it, installed Windows 7 and then went to install Ubuntu.
That didn't work because no Ubuntu version whatsoever (10.04, 11.04 or 12.04) were able to even detect partitions on my harddisk.
So I decided to go the other way, install Ubuntu then try installing Windows and fix grup after it gets broken due to Installing Windows.
Using GParted, I created an NTFS partition and then rebooted and tried installing Windows 7.
That failed, the error message was speaking about GPT table.
I am trying to just understand what's going on here, why am I unable to do what I was perfectly doing on my old machine(please in enough detail; let me know if I need to provide more information)? and how can I fix this?
I am trying to avoid using Wubi so if there's any other way, I'd take it.
Currently running on Ubuntu if I need to use some tool to extract more information about my HDD
EDIT:
Thanks, fabricator4.
I indeed used gparted to delete my partioning table and MSDOS table worked just fine(my HDD's size is 500 GBs only).
I did consider installing 12.04, the thing works just fine on live CD and when I ran the installer it recognized Windows partitions and all; I made a partition for it and installed.
Once I reboot and choose at the GRUB screen Ubuntu, the screen goes off(totally off), then on again and kinda blinking; I hear the welcome music of Ubuntu but I cannot see anything, except a very very thin line at the top of my screen where I can see the mouse.
It's weird, it did work on Live CD just fine, why is it crashing when It's installed? could be a graphics card problem? is there a way to fix such a thing?
P.S While the system is booting, I do not see the Ubuntu mark and the dots going to indicate it's loading, I have a blinking screen instead.
