no boot option in BIOS

[patrick]

Hi,

i tried installing linux lite 2.2 now, 3 times..
i've formatted the harddisk, created new partitions: /dev/sda ext4 mount option / and /dev/sda5 swap, also there is /dev/sda2 extended.
The installation was succesful, but linux lite isn't in the BIOS. (tried 2 times like this)

So now, in the installation process, i chose the option to delete previous OS (linux lite 2.2) and overwrite it with the same OS.
Again, installation worked fine, but still the linux lite isn't in the BIOS.

linux@linux:~$ sudo fdisk -l

Can someone help to solve this?
