[SOLVED] Ubuntu 10.04 wont boot

[BerenErchamion]

Hellow everybody!
I have recently acquired a Toshiba Satellite L500-ST5507:
Intel I5 430 Processor, DDR3 memory, Intel Integrated Graphics, Intel 5 series 4 port SATA AHCI Controller, Realtek RTL 8191SE Wireless LAN, Intel 5 series/3400 series Chipset family USB Enhanced Host controller 3B34.
In this laptop, I have been able to boot ubuntu 9.01, though i couldnt get the wireless to work (among other things).
Now, I wanted to try Ubuntu 10.04, but I find that I can not even boot the computer. Wen I boot from the live cd, I can see the menu screen, but when I choose the "try without installing" option, all I get is a screen full of weird messages, the last two of them are:
[0.600438][<c0104087>] kernel_thread_helper + 0x7/0x10
[0.600375][<c07a3308>] kernel_init + 0x0/0xbf
I tryed wubi installation, but the same screen comes up when rebooting.
I will be thankful if anybody can explain me what is happening here and if there is some way to solve this problems in order to install ubuntu in a dual boot mode in this laptop.

You should boot into the BIOS and look at the settings there. Since these systems are shipped with Windows there may be some issues with how the BIOS is configured, especially regarding to legacy USB or sata->pata translations, etc. In truth, I've had very few problems running Linux on Toshiba laptops and netbooks, although it is possible that there is some problem wtih this one. The other possibility is that your boot disc is corrupted.

Thankyou Rubberman!
What is exactly what I should look at in the BIOS settings? About SATA controllers, I found the following options, * meanscurrently selected item.
SATA interface setting
[Performance]*
[Battery life]
eSATA
[Enabled]*
[Disabled]
Advanced->System Configuration->Sata Controller Mode
[AHCI]*
[Compatibility]

The only option I tried changing is de AHCI mode to Compatibility mode, but the same messages come up during livecd boot.
About the corrupted Disc... Do you refer to the hard disc on the laptop or to the live cd? I have burned the iso images 3 times in differnt discs, the last one is a DVD, though I havent tryed them in other computers I think this is not the problem.
Thankyou for your help!

Do you refer to the hard disc on the laptop or to the live cd?

He is refering to the Live CD. Usually before burning a ISO to a CD or DVD. We md5sum check the Iso.

Then burn the Iso at the slowest speed possible on the burning program you are using. Strange that the same error comes up with a wubi install. But I know nada about using wubi as I don't run Linux inside of Windows.

I would suggest you to try same LiveCD on other machine and check if it boots up fine.

[BerenErchamion]

Thank you all for your responses!
At the moment, I have successfully booted and installed ubuntu 10.04 in a VirtualBox machine, using the same live cd. In Addition, I run md5 as suggested by rokytnji and got:

d044a2a0c8103fc3e5b7e18b0f7de1c8 ubuntu-10.04-desktop-i386.iso

which is in agreement with one of the entries in the Ubuntu Hashes page. I can try it in other computers as soon as I have them available.

I will be thankful with any other ideas on solving this issue.

Well, if it boots a 9.04 disc, but not your validated 10.04 disc, then there is likely some issue with 10.04 on this hardware. If that is the case, then I'm sure the folks at Canonical would like to know. Post this information on their user forums to see if either they have run into the problems or not. Since 10.04 is so newly out of the lab, it is entirely possible that there are problems.

have you tried to disable acpi in bios yet? I have had issues with this on a couple of systems and by disabling it the problem went away. Not the same issue through but worth a shot.

[BerenErchamion]

Tank you all again.
Please forgive my newbe-ness, I cant find an ACPI option in the bios settings. I could not find a sensible tutotial on InsydeH20 Bios, which I read is responsible of many issues in toshiba laptops. This guys at canonical did not answer my question yet. Actually, I found someone else has a very similar problem, but he did not get any answer either. Do you think I should try another distro?

[rokytnji]

Do you think I should try another distro?

That is the beauty of using Linux Live Cds. You can experiment with what works and what does not work. If One distro doesn't support your hardware. Another distro may be able to. You only lose the price of a blank CD. Unless your gear can boot cdrws or usb. Then all that is lost is a little time and effort.
