Chromium OS not booting from HDD/SSD

[adam hardwick]

I have an Asus x550c Windows 8 Laptop i would like to replace Windows with Chromium OS on a seperate SSD, i can boot the USB and do everthing like normal, install it and everything, but when i come to boot from the SSD the UEFI BIOS screen does not detect the SSD as a bootable device and thus cannot boot from it, if i plug it in to an external caddy and plug it into the USB port i can boot from it as normal its just the internal SATA port that its not letting me boot from, does anyone know what the problem might be? I have also tried to install on a HDD but to the same result.

 

Thanks

If you disconnect the SSD completely from the mainboard, does it still boot to USB?

I had an issue similar to this and found that where the kernel was (dev/sda3) was not where the bootloader was trying to find it (/dev/sdb3).

Yeah boots off the USB as normal tried doing a dual boot method with Ubuntu but comes up with a grub selection screen with three /dev/sda3 boot options but when I select it comes up with kernel panic

Ah, maybe try and edit the config files and remove the "quiet" boot option. To do that you will actually have to mount partition 12 on your image and there you will find a few config files. Likely you are booting from syslinux, in which case the cfg files are in a subdirectory on the partition /mountpoint/syslinux . There are 3 to worry about A B and USB (cant remember their actual names off the top of my head). Go in and remove the word "quiet" from each and see what happens.

If you are booting via EFI, then the config file is in the root of of your mountpoint I think.

Have just tried what you suggested and I still can not boot internally I might end up getting a nano USB drive as that boots like normal

OK, if you are doing an EDI boot, then the config file is the grub.cfg file. The other thing I forgot to mention is to change the console that it is outputting to. So change console=tty1 and loglevel=7. That should start outputting a bit more data for you to look at.

I mean EFI boot, not EDI....

Right just got it working but i needed to get an optical drive to hdd adapter, seems like it gets detected as a bootable hdd that way
