View Full Version : [ubuntu] 10.04 won't boot; neither will Live CDs or USBs.

Hi,

I recently upgraded to 10.04, and now it boots until it gets the splash screen, at which point the display goes blank and stays that way until I hard reset.

I tried loading a Linux Mint live USB, and it said "no operating system detected" when I tried to boot from it. When I put in a CD, it reads it for a couple minutes (with a blank screen) then boots from harddrive (which doesn't work, of course). I tried an Arch Linux USB, which behaved the same way as the Linux Mint CD.

Unfortunately I set GRUB to immediately boot to the harddisk, so I can't boot into recovery mode.

What do I do? My laptop has been bricked...

If you can still reboot and get to the Grub menu (hit Shift I believe) then look at this and the post following it:

Regarding this known bug affecting Intel graphics chipsets:

https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes

I have found/stumbled upon by accident a workaround that allows the LiveCD to be booted after people reported the process stalling at a black screen.

This is taken from my reply to another post on the forum where someone, like me, was having issues with even booting the LiveCD.

I hope this helps people with Intel graphics chipsets.

Good luck!
:smile:

I started the thread for this issue and Rubi1200 was kind enough to post his findings and get me going. Once I got the Live CD to boot, it installed just fine and on reboot came up to a fully functioning desktop. I didn't need to use the workaround he linked to, the drivers were already installed correctly. So it appears -- and this is just from my experience I'm basing it on -- that the drivers get installed correctly, but are not active/included on the Live CD.

If interested, all the gory details are here:

Good luck!

You should be able to hit "esc" when grub has loaded to get the boot options. You might try shift as well. If your laptop has a boot logo, then just keep hitting esc after the boot logo. It may take a few times to get the timing right.

On some laptops you can hit f8 or f12 to choose the boot source, you need to push those immediately after starting.

Do you by chance have an intel 8XX or 915 video set? If you search for lucid blank screen, you should see some of the solutions. Also look here:

You could give my Hybrid Image of Ubuntu a try. It is basically the ISO morphed into a combination ISO plus hard drive image. Be sure you have configured or selected the USB device to be booted in the BIOS. If your boot choices are "hard drive" and other things, then there is probably another BIOS selection to choose which hard drive among many. Most USB memory sticks are hard drives.

http://slashusr.net/ubuntu/10.04/ubuntu-10.04-netbook-i386.iso.imgTo use these, you need to download the image onto a computer where you can perform a raw write from a file to a hard drive device (the USB memory stick). You can do this in another Linux system with the "dd" command (example assuming the USB memory stick is /dev/sdc):


dd if=ubuntu-10.04-desktop-i386.iso.img bs=1M of=/dev/sdc oflag=direct

There are a couple raw write programs for Windows. There was a wiki for that on the Ubuntu wikis site for an earlier netbook remix that was distributed in a .img format instead of ISO.
