I tried to install ubuntu 13.04 on my new Lenovo G500 which came pre-installed with Windows 8. I shrunk the main OS (Win 8) partition and then disabled fast boot in the power options in Win 8. Then I entered the UEFI and changed the mode to Legacy mode. Then booted from the Live USB drive and installed ubuntu. During installation I created 2 mount points (/ and swap) and when I tried to proceed it warned me of a requirement to have another boot partition of 1MB in size. I did that too. May be this was a mistake (dont know). Then tried to run ubuntu and things were fine. Restarted the laptop to see if Win 8 also worked. It did not and was asking to insert the Win 8 disk. I recalled there was a boot repair utility for ubuntu. I installed that and tried to repair the boot partition so that both OS would boot normally. The boot repair utility changed the mode to UEFI (I saw that happening) and then when I restarted the laptop I got the following message
error: file '/boot/grub/i386-pc/normal.mod' not found grub rescue>
Now the problem is that I am not able to restore my system. I am not able to get into the BIOS. Nor does the laptop recognize a Live USB drive, nor do I have a Windows installer CD. Can anyone help me with this situation?
