Did installer throw any error during installation?
Press any key at startup. Does GRUB Menu having Windows OS and Ubuntu entries appear?

Boot up from Ubuntu LiveCD, open Terminal and execute this :

sudo grub
find /boot/grub/stage1
find /grub/stage1

Post output here.

in the advanced option in boot loader installation disk there is selected "DISK0 " as default
is this is the problem ????

Ubuntu has been installed in Second disk but GRUB confs are installed in MBR of First Disk. This setup doesn't work in a few machines. Its GRUB/BIOS compatibility problem.
Post the output of this

sudo fdisk -l

* Its small L in fdisk -l.
