asus eeepc 1015cx boot stuck

[svrkispm]

Hello,
I have and USB key with Ubuntu 10.04.4 LTS (kernel 3.2.0) on it. Recently I have bought an Asus EEEPC 1015 CX. I am unable to boot this USB key on it.
Moreover, I have older USB key with 10.04 LTS installed (kernel 2.6.33) which also doesn't boot.

I was suspecting this to be a kernel problem, so I have tried other kernel versions, namely 3.5, 3.6, and 3.7 from http://kernel.ubuntu.com/~kernel-ppa/mainline/, but this didn't help.

Symptoms: in recovery mode: boot process prints "Loading initial ramdisk ...", then screen refreshes and it gets stuck with cursor blinking in top left part of the screen.
in normal mode: all I get is a blank screen.

Thank you for any ideas.

The following reply assumes that you have some experience with linux, and that you have at least a live system running on some computer. (Otherwise let us know, and we can help you do the corresponding things from Windows.)

I have booted an eeepc from a USB pendrive with Ubuntu. I do not remember that I had to use some particular boot options. But it might be important how to prepare the USB device.

Usually it works if you

- make a partition, format it to FAT32, and add a boot flag
and an lba flag.

- use Unetbootin to transfer the live system from the iso file to the USB drive.

I suggest that you try with the newest long time support version, 12.04 LTS. And for an eeepc I suggest Lubuntu or Xubuntu instead of vanilla Ubuntu, so download those iso files

Have you tried any boot option?

The first one to try is nomodeset.

See for example
https://help.ubuntu.com/community/BootOptions

This is straight-forward when you boot from a CD or from a USB drive, that you have cloned directly from the USB drive, while it means editing the boot menu in a Unetbootin system.

Hello,
thank You very much for Your swift reply,
"recovery" grub record is using nomodeset by default (so it didn't help). Currently the only nonstandard boot option I am using is "elevator=noop". I have tried boot options "noacpi, noapic, novga", it didnt't help either.

I am using 10.04 and I would very much prefer to continue using it, I want to avoid the upgrade to 12.04 at all costs. 10.04 is LTS and this notebook has some sticker saying "ubuntu certified" on it, so I expected, that with some effort this should work too.

I have few years experience with linux, and I would love to prefer some "nice" solution (imo building my own kernel is NOT a nice solution, but as a last resort I am willing to try this too).

For the start, is there any way to determine WHY it gets stuck after loading ramdisk? I would like to see some very verbose output on what it is doing and where it fails, how can I enable it?

Sorry, maybe I wasn't clear in my previous post: the mission objective is not to make any ubuntu work on this machine, the mission is to make my usb key with my standard ubuntu 10.04 boot on this machine.

The usb key is perfectly fine, it boots fine on maybe 4-5 other machines (namely my older asus and my thinkpad), and it looks like this:

sudo fdisk /dev/sdc
Password or swipe finger:

One new discovery - 32 bit ubuntu 12.04 with kernel 3.2.0-x DOES boot.

I have tried very simillar kernel, but my system is 10.04 and 64 bit, and it DOESN'T boot - may this be the key?
