I have a PC with 2 HDD:

  • 1 of 120 GB SDD (with Windows 7)
  • 1 of 2 TB (for all my data)

Now, I partitioned the SDD in two, so I could install my Linux distributions.

No problem until here. I write my ISO on CD/DVD, go on with the Live-CD, install all the things and, when I reboot, I see GRUB where I can choose from Windows or the Linux distribution.

The problem comes here: when I try to start ANY of the distributions (Fedora, OpenSUSE, etc.) I get a black or white screen. With Fedora I was getting a flashing thing on my monitor.

I guess the problem comes with my graphics card (an ATI 6800 Series). But why is it that I can use a Live CD without problems?

And how can I solve this thing?

P.S. At some point I managed to install Ubuntu/Kubuntu on my PC, so I am sure 100% that is possible to make it work, the problem is: I don't want to use these distributions.

Could you elaborate ? Do you see any Fedora/OpenSuse loading images or messages, or a blinking cursor on the screen ? –  Praveen Oct 25 '12 at 15:27
    
Nope, as I sad, I only see or a black screen or a white screen. –  Con7e Oct 25 '12 at 15:38

Assuming it's just XServer Failing

Try this first, after a minute of that - hit Ctrl+Alt+F2.

That might drop you to a TTY screen where you can login text-based and do the updates/installs there.

Assuming it is the Graphics

(which would surprise me, normally if that's the case it dumps you into TTY)

Boot into a liveCD (whatever you installed from might be the best). Make a place to mount the partition of your linux device and then you can chroot in and install the graphics you need to test if that is the issue. Chroot should be installed by default on most liveCDs.

1) Boot into the liveCD (should put you in as root).

2) Make a mount point you know of for your local disk

mkdir /mnt/brokenlinux

3) Find the partition of your linux drive (outputs all drives and their partition info)

fdisk -l

4) Mount the linux installed partition to the mount point you created

mount /dev/sda# /mnt/brokenlinux

5) Chroot in and then do the updates and such.

chroot /mnt/brokenlinux

I don't know which linux you're on, so I can't tell you what to update. I know arch is pacman -Syy && pacman -Syu, debian based is apt-get update && apt-get upgrade.

Make sure your graphics card is recognized and then find which drivers you'll need.

lspci | grep VGA

Maybe it's actually GRUB not seeing the right partition

If you know the partition, during boot at grub, hit "e" for edit and check that it's looking at the right partition.

I don't recall 100% (I use syslinux), but I think it looks like (hd0,#). If you try that and it fails, nothing is saved so rebooting will revert to default.

If that is the issue, however, when you get into linux just edit /boot/grub/grub.conf with the correct #.

I tried to get in the shell, but once I press ALT+CTRL+F2 I only get in a black screen with no test and even if I try typing something it doesn't work. –  Con7e Oct 25 '12 at 16:19
    
Did you try confirming that Grub is pointing to the right location? (3rd item in my list) –  nerdwaller Oct 25 '12 at 16:30
    
Yes, GRUB definitely sees my Linux partition. At the moment I have open suse installed and when I try to start it I only get the green screen (as the logo of opensuse). But I just noticed that at the very top of the screen with a width of 1 px I can see my mouse moving, so is definitely a driver problem. I'll try later to install Archlinux, where I can actually install by hand all the drivers. –  Con7e Oct 25 '12 at 16:36
    
Yeah, I haven't liked Suse much at all. I definitely recommend Arch if you are willing - I run it and it's been my favorite OS. The other option for you is to get to TTY, which could be done via the CHROOT method I mentioned and installing the drivers. But really not worth the effort if you're doing Arch. Let me know if I can be of help with Arch. –  nerdwaller Oct 25 '12 at 16:48
    
I will. Thank you nerdwaller. –  Con7e Oct 25 '12 at 17:24
