Linux

Might give it another shot. Having trouble now with even a fresh install of win 7. After running windows update, it kills my fps for even the simplest 3D games, which is ludicrous. I've got dual Geforce 280Ms in SLI mode on a system with 8GB of 1333mhz RAM. I should be getting more than 60fps, yet it'll drop to 7. I've pretty much had it with windows.

I can't even get the bloody service pack to install! It fails every [expletive deleted] time! And then I gotta go to the microsoft site to download some tool or another that's supposed to fix the problem. I run the tool and it hangs and never does anything.

Ok, installed Ubuntu again. It went completely this time, but when it boots, I get a "grub rescue" prompt. Anyone have any ideas?
 
Fresh install, drive partitioned. Installed Ubuntu on my main hard disk (two SSD drives run in a raid as one drive). Not sure about grub, just ran the live CD and told it to install as the primary OS.

(Edit: I'm posting after booting again from the live CD under run ubuntu without install, so I can get to the net to figure this out)
 
Ok... managed to get to a command line and familiarized myself with basic folder movement. It seems my hard disk is under /media/(long alphanumeric string/. There's a dev folder, but no sda folder.
 
I'm not even to that point yet, Captain. Yes, SSD drives, intend on playing games, but cannot yet get a fresh ubuntu install to boot. I'm working off the live CD at the moment. When trying to boot, it takes me right to that recovery prompt. From what I can dig up on the 'net, grub didn't install. Or I think so.
 
Little subnote: Tried to download and install the linux graphics drivers. Got .run files, but can't seem to use them.

grub-install from your Live-CD should do the trick.

And to install the drivers, drop out of X, navigate to the folder you downloaded to (~, most likely) and type

sudo sh NV*.run

That should do the installation for you.
 
Awesome! trying now

#EDIT: Hrm. It's saying I need to specify a location. Not sure where to put it.

Give this a go:

How to Restore the Grub Menu after a Re-Ghosting:

1. Boot from a Live CD, like Ubuntu Live, Knoppix, Mepis, or similar.

2. Open a Terminal. Go SuperUser (that is, type "su"). Enter root passwords as necessary.

3. Type "grub" which makes a GRUB prompt appear.

4. Type "find /boot/grub/stage1". You'll get a response like "(hd0)" or in my case "(hd0,3)". Use whatever your computer spits out for the following lines.

5. Type "root (hd0,3)".

6. Type "setup (hd0,3)". This is key. Other instructions say to use "(hd0)", and that's fine if you want to write GRUB to the MBR. If you want to write it to your linux root partition, then you want the number after the comma, such as "(hd0,3)".

7. Type "quit".

8. Restart the system. Remove the bootable CD.

no idea what the su pass might be. Tried the pass from my original ubuntu install, didn't work. Also tried both Ubuntu and ubuntu. Didn't work either.

You need to have a bunch of tools and "materials" installed. On the tools side there are 'make' and 'gcc' etc and on the "materials" side there are things like kernel-sources.

Next thing is that you probably need to disable the 'nouveau' opensource driver.

(What you precisely need to have installed, and how precisely - if at needed at all - blacklisting of nouveau works on Ubuntu, I don't know. I could point you to some handy articles for openSUSE though.)

And when that is done, simply navigate to the folder that contains the NVIDIA drivers and type: 'sh NV' and then hit TAB to autocomplete and enter to execute.
 
It's telling me grub isn't found.

#EDIT: Ok, navigating around, I found media/(long alphanumeric string)/boot/grub. Sudo grub in there gives me the same error.

Information overload heh. Thanks for the help, guys. I really do appreciate it. Sorry to be such a bother!
 
So I'm guessing sudo grub-install /media/9ce176d0-f6e5-4bd7-ab8b-aeda57a9228e.

#EDIT: Which gives me this:
ubuntu@ubuntu:~$ sudo grub-install /media/9ce176d0-f6e5-4bd7-ab8b-aeda57a9228e
/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?).

grub-install /dev/mapper/nvidia_aiachche1

(/dev/mapper/nvidia_aiachche1 would be your RAID setup)
 
Crud. I think I'm gonna need to divine what the su password is supposed to be. Got this error:

ubuntu@ubuntu:~$ grub-install /dev/mapper/nvidia_aiachche1
rm: cannot remove `/boot/grub/915resolution.mod': Permission denied

#EDIT: Ok, managed to change the pass and login as root. Still got an error...
root@ubuntu:~# grub-install /dev/mapper/nvidia_aiachche1
/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?).
