I installed seabios in toshiba chromebook 2, which allows me to boot from a usb drive, and I booted into lubuntu and installed it on ssd card, but when chromebook boots up does not detect the boot sector or boot drive other than the usb drive. Installation went on without any glitch. Does any body have any idea why I'm unable to boot off the ssd card?
I'm running toshiba chromebook 2 cb35 intel
Thanks

After digging a bit regarding CoreBoot, I found this. Hope it helps

I think that's about the bios.. I already installed the seaBios and can boot from a usb flash drive with ubuntu on it, but I'm having trouble booting from an internal ssd card which has ubuntu installed. the bios seem to recognize usb flash but not ssd card... I think the problem might be something during installation. I could be wrong, I'm just started with this

I'm not sure how you would have installed to the SSD card if it is not recognized in the BIOS. Did you accept the defaults during the installation? Where did you install the bootloader? If you boot the Ubuntu install medium and open a terminal, run the two commands below and post the output of either.

Lower Case Letter L in both commands.

yes you're right. ssd is recognized by the bios, the installation went through without problem. but when I boot into ssd chromebook can't find the boot sector or grub might be corrupted. I get error "can't find boot drive" and then stays at the grub> prmpt

Did you verify *buntu installed on the correct drive? By default if I rememeber correctly (I have several chromebooks, including 2 cb35-B's currently (1 I'm selling)), it wants to install to /dev/sda, but it needs to install to /dev/mmcblk0 which is the ssd. That would explain why grub isn't seeing any bootable drive.

You could download the boot repair software from the link below to the Lubuntu install media and run it. Make sure you select the option to "Create BootInfo summary" and post it or a link to it here. That will give more details about the computer and someone might be able to offer a specific suggestion.

I'm pretty sure I installed to right drive; one is 16 gig and the ssd is 32 gig. During install I selected the 32 gig one. which is listed as
the internal device which is listed as /dev/mmcblk0 is seen by lubuntu as /dev/sda0 and is only 16 gig... other than that fdisk -l outputs a mess of rams devices I have not seen in others laptops...

if you take a look at the disk above has two partition heln and one is marked as the boot partition, that's the root partition, and then there's the swap partition, but when I boot the chromebook is not recognizing it... any help appreciated

Unless you've got a weirdo chromebook2, every cb35 I'm aware of (cb35-a3120,-b3300, -b3330, -b3340,-b3350, -c3300, -c3350) has only a 16 GB ssd, none of them were offered with a 32. What model do you have, if there is one with a 32 I'd love to get that (16 is sufficient, but I'd love to have a 32 model).

yes the internal is 16 G, but I'm installing to the external which I put in a 32 G. But no luck. Even though is listed during boot, so it is recognised by the BIOS. Mine is a CB35-B3330

OH!! You're trying to install on the SD card!! I totally didn't understand that from your earlier post.

Create a 512 MB /boot partition on mmcblk0 (the 16 GB emmc internal SSD), then have your swap, / & /home (or / if you don't use a separate /home) on the SD-CARD. This should work (although I haven't actually tested it). The limitation of this hardware makes the SD-Card not directly bootable.

I created a 200 MB /boot partition on internal SD, and installed / and swap to external SD, and IT WORKED!... thank you very much... does it really matter the size of the /boot partition, I made it 200MB, I think that's enough....

thank you!

No, I just go with 512 because it's a nice .5 GB. smaller makes odd fractions, and that annoys my mind.
