Wubi

Installing Ubuntu- Stuck Mid Boot-up

Asked by Murphy Spence

Hello all!

My name is Murphy; I am quite the newbie to the Ubuntu/Unix community, but I'm happy to be here. I'm trying to get started by installing Ubuntu 10.10 Desktop Edition on my laptop which already runs Windows7. I run the 64-bit version on a Toshiba Satellite E205; my processor is Intel Core i5CPU, M430 at 2.27Ghz.

I downloaded Ubuntu (Wubi), and followed the onscreen instructions without a hitch until I restarted my computer. When I did restart, I chose Ubuntu and waited for it to load. However, midway through when the code was running down the screen, it suddenly stopped at the following line:

[0.596289] [<c010363e>] kernel_thread_helper+0x6/0x10

I tried the Live CD before on my USB, but that had similar issues with the code stopping. I was wondering if I could get any help, or if I missed something ridiculously obvious. Thank you so much for your time!

Try using the acpi=off kernel boot option. This thread explains how (there's even a special entry for the Wubi install - post #8). Try it first using the live CD.

I'd also check for any available bios updates. The above is just a workaround and will disable certain (perhaps important) functions like battery indicator and cooling fans.

I've searched around for help on this problem and the best I can come up with is something on the E205 under 10.04: http://ubuntuforums.org/showthread.php?t=1415525 (the part that looks useful comes further down in the thread - not the vgaxxx option)

I can't vouch for this and since it is for a different release it's probably not going to help, but it might give you some starting point to search from. In the meantime, if acpi=off is working, you could use that.

Actually, I think you just need to supply the following boot option: acpi=copy_dsdt

Hi! Thank you so much for your help.

I'm a little reluctant to turn acpi=off, since my laptop fan has trouble keeping my computer cooled down enough when it's running in the first place. If it were off, I'm thinking very bad things might happen.

I've also been looking for a BIOS update; I run Insyde 1.2, dated 3/14/2010; however, on the Insyde website, I couldn't find anything who's name looked like that. I could only see H20, DIY, Q2L, and Humanos.

Now, final stupid question: How do I supply a boot option? Sorry, super new at this. ^^; I'm going to go try what the link recommended in the mean time. :)

Thank you for your help!

Hey! I just tried to follow the link's instructions; unfortunately, I couldn't quite figure out how. In the mean time, though, I was messing around and managed to stumble upon the GRUB menu, where the ACPI Workaround option worked. It started and installed, but when it was through (I think) I just went back to the start up screen that appears when I turn on my computer, with the option to run Ubuntu or Windows 7. I selected Ubuntu again, and a new GRUB menu came up, but both of the Ubuntu options resulted in the same error message I listed in my first post. Drat!

That's normal actually. You applied the ACPI workaround to install, so that
supplied acpi=off for you. But that's doesn't persist after the install
(just to boot the Ubuntu environment that runs the installer).

So you just need to supply the override again. Once you see the grub menu,
hit 'e' to edit the first entry. Use the arrow keys to navigate to the bit
where it says "quiet splash" and change it to "quiet splash acpi=copy_dsdt"
 (don't enter any quotes).
Then hit CTRL+x to boot.

Note if that works it should allow you to run normally - fans, battery
working.
If that fails, try acpi=off instead.

This STILL won't make it permanent. Follow the instructions here (
http://ubuntuforums.org/showthread.php?t=1613132 )to make it a permanent
boot option. (Ignore where it says "(not for wubi)". It is the same.
