unable to boot lubuntu in chrombook 2 after install (intel)

[miatech]

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 (from a usb boot), but when chromebook boots up does not detect the boot sector (grub) 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
