Well, first the Windows "no hd found" message is, most likely, because M$ is automatically ignoring partitions it doesn't understand. And, of course, M$ doesn't understand Linux. (On several different levels, eh?)

To fix you problem, boot from your Fedora installation medium, and use the "linux rescue" option at the first prompt. (Actually, if you're using the 4 CD set, I think you just boot the fourth CD.)

That should locate your installed system, log you in as "root," and suggest that you use the command chroot /mnt/sysimage to switch to your installed system. Do that.

First, to fix you boot problem, try re-installing GRUB. Just enter the command

Code:

grub-install /dev/hda

Code:

grub-install hd0

(The two commands are equivalent. The second form uses the GRUB device format, the first, the Linux format.) Now you should be able to reboot, but I uspect that the X-windows system will fail to start.

From your problem description, it seems to me that Fedora does not have a good driver for your video card. This is usually because the driver software has not been released under a GPL, and, by policy, Fedora will not distribute anything not under GPL. So, let's first see if we can get the correct video drivers installed. If your card is from nVida (e.g., GForce, etc.) or Raedon(e.g., ATI, FG, etc.), then the correct driver should be found in the livna repository.

Note: The following asumes that you have a live, working, internet access.

To add the linva repository to the YUM repository search, enter the following command:

Code:

rpm -ivh http://rpm.livna.org/livna-release-6.rpm

(Assuming you've installed FC6.)

The most common video drivers are nVidia and Raedon (ATI). If you have an nVidia card, enter the command:

Code:

yum install kmod-nvidia

and, for an ATI card, use

Code:

yum install kmod-fglrx

Now a reboot should get you into GNOME (by default) or, if you installed it, KDE.

Hope this helps.

when i try and do
grub-install /dev/hda it wont work
i tried sda1

both times comes up with /dev/sda1 does not have any corresponding BIOS drive??
i'm guessing that cant be good..

yum install-kmod nvidia worked fine, but startx still presented me with the same screen..which is basically nothing.

any other suggestions for this :newbie: ??

How about #grub-install /dev/sda ??

Ok, so, i managed to get fedora to boot now, but to text mode. so i edited the inittab file to 5 instead of 3.
NOW MORE PROBLEMS
it loads into graphics mode, but all that shows up on scree are vertical lines.
i'm running a nvidia geforce 6800.
anything special i need to do for this card?

NEVERMIND, i guess i just had to wait for a long time ??
its working now.
i'm never going to turn it off haha
