Ubuntu Won't Boot!!!

Submitted by eimaj on Sat, 2008-05-24 18:38.

Help!!I recently installed Hardy Heron, from a live CD i burned (and checked) myself.I managed to successfully set up my wireless (using ndiswrapper), and install a driver for my Nvidia graphics card.After installing / removing some applications, using the standard 'add / remove software' app, I got told the system needed a reboot.So i rebooted - my laptop turned off, turned on, the bios came up, detected no boot cd, then the ubuntu splash screen came up, with a progress bar (as usual). However, when the progress bar got to the end, the screen simply went blank, and after a second the ubuntu login sound was played.This is as close as i get to logging in - the screen simply stays blank, and my mouse/keyboard dont have any effect. When i push the power button to turn my laptop off, i get a quick flash of a bios screen, and then the standard ubuntu splash screen with a progress bar showing shutdown progress appears.What can i do? What is causing this? Am i being a complete n00b and missing something? Please help!

Because you can hear the sound it looks like it has installed, but it doesn't recognise your video card (=start the xserver). Have a look at "How to get started with no GUI" on http://kubuntuforums.net/forums/index.php?topic=3085112.0

Thankyou, i think that must have been the problem.After running the xserver, ubuntu booted just fine, but had disabled the proprietary driver i had installed previously..Thanks

Two things to try to get Nvidia back. 1) The Albert Milone script called Envy which is available from http://albertomilone.com/nvidia_scripts1.html. It works for most people, but not all people - it has worked for me before, but didn't in Hardy; or 2) Get Nvidia from the Nvidia site. It is not hard to install.

Ubuntu 8.10 won't boot

The base install works like a charm. I just enter through the program, sacrifice my entire (hd0) 500G SATA drive to the "guided partitioning" process, remove the CD, hit enter - and -End of story. The thing won't boot no matter what I do. The machine just stopped dead right after the POST check.So here's what I did: I re-installed Debian, my previous installation, using the same harddrive, and told the installation program to tweak the MBR and /boot partition (why doesn't the ubuntu install livecd have nifty options like that? sure, the installer is easy to use - unless it doesn't work!). Then I re-installed ubuntu, again using (hd0).Now, at boot, at least I got the grub menu. But keying enter got me in the BusyBox. So I rebooted and got myself into a grub commandline, to try some stuff. I couldn't get it to boot no matter what "root (hd#,#); setup (hd#)" I entered. I did discover one thing though:Debian assigns a completely different range of drive numbers to my drives than ubuntu.My machine has 3 SATA drives, and 2 IDE drives on a plugged in PCI IDE card. It also has a combination card reader. It's starting to look like with ubuntu, the cardreader is numbered as the first 4 SCSI devices, while the SATA and IDE drives are given drive designations higher than those. I want to install ubuntu to the same disk Debian was first on: the first sata drive - but apparently my BIOS, Debian and Ubuntu *all* have different ideas as to which drive is which.I still don't know why the ubuntu installer can't figure out how to correctly configure my MBR and grub, but at least I know the direction to look in.If any of you knows anything about this; don't hesitate to lemme know: my system's been offline for 3 days now, and it's starting to hurt :|Thanks!G.
