Recently, I'm upset. Everything began with buying a brand new Asus laptop and preparing it according to my requirements. My needs are very simple; I need dual boot windows and linux.

Firstly I've installed windows 7 and burned my favouite linux distro( debian 6 ) in DVD.
Debian 6 has old kernel so my wireless card cannot detected. I've been upset. As you can appreciate, I need new kernel at least linux 3. So I changed my distro to ubuntu. I hate it because of unity. Still I was not happy. I changed it again to Debian wheezy. But it still has been got bugs. And with it, my system cannot response some times with xfce. Then installed Slacware64-current. But... It's package manager really problem. Then fedora... Ah god. "Boot loader installation failed. Your system may not able to boot." Now I don't use any linux distro. But I have to use... At this point what can you do? Suggest me the perfect system.

Hi:

In order to assist you we will need more information.

Is your Asus laptop a i3? and i5? or an i7?
Is it a dual core or quad core?
Is the HDD 500? 650? or 750?
What NIC (network interface card) do you have?

Open the terminal and post the output of this command so members can diagnose for you.

Asus N56VM. i7. Quad. 1 TB of hdd. 8GB of RAM. Geforce GT 630M 2GB gp. Atheros AR9485WB-EG wireless.
I can't give what is result of lspci. I said that I have no linux now.

PS: My disk was gpt. I converted it to mbr with windows's DISKPART

Why don't you try Mint. I use it and it's got both ubuntu based as well as straight Debian based options. If you go with the Debian based option you can change your sources.list and there are tutorials on how you can do this in their debian forums itself. I'm using this for the past year and nothing's gone wrong (although to be fair, my system is much older than yours).

Another option is kde. You can go with kubuntu which is the kde version of ubuntu or go with mint itself which has a kde version. Another option, if you want a rolling distro is to go with the debian version and install the KDE-full package giving you the option of booting from different window managers. With 1 TB of HD, space is not a problem for you.

I'm giving you these options because if ubuntu and debian installed on your system, then most current versions of mint or ubuntu will install. And since it is the Desktop environment that is causing you the mental agony, change it, not necessarily the distro.

You might need a driver for your Atheros NIC-

Did your Asus arrive w/o and OS or did you have to install Windows 7?
