After installing ubuntu 12.04.2, 64bit to my acer aspire 5560-7414 laptop, on a single 500gb hard drive.
After installation, and manually setting my hard drive partitions in the ubuntu installer as / 20gb, /var 20gb, /swap 8gb, and remaining /home (all under ext4 except the swap), I successfully completed the installation and it asked me to reboot.
I did and even before grub appeared, I received the error:
Error file not found, error you need to load the kernel first
I did some googling, found a suggestion to sudo update-grub did that received the error:
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
so I googled that error and did boot-repair which recreated this log
While running boot-repair, I received a message that
running boot-repair, "the boot of your pc is in EFI mode but there's no EFI partition detected. and retry after creating a EFI partition , FAT32, 100MB-250MB, start of disk, boot flag."
More googling, I tried to remove the UEFI mode
I have not found legacy mode or any other mode that would disable the UEFI in the boot screen (that I obtain by hitting f2) to my bios (or UEFI ) - Phoenix SecureCore Tiano, v1.15
I have found the UEFI Installing Tips http://ubuntuforums.org/showthread.php?t=2147295 , a nice synopsis of some of problems that users have experienced and possible solutions but no clear solution of next steps.
Should I continue to try to disable UEFI (if so, how) or install a EFI partition ? What are my other next steps /
