When I buy laptop recently,it already install win7.

I remove D to install ubuntu 12.04 64 bits.

At first I only set partitions like this,and I don't change any other partitions related with win7:

  swap 16GB
  / 150GB

But I got this message:

  The partition table format in use on your disks normally requires you to create a separate partition for boot loader code. This partition should be marked for use as a "Reserved BIOS boot area" and should be at least 1MB in size. Note that this is not the same as a partition mounted on /boot. 

So I try to add one partition:

  biosgrub 1MB

And I can install ubuntu successfully.

But when I boot,it shows:

  Reboot and Select proper Boot device
  or Insert Boot Media in selected Boot device and press a key.

If I change BIOS boot option to Windows Boot Manager(P0: ST9750420AS), it can boot into win7 normally.

Boot option only have 3 options:

  Windows Boot Manager(P0: ST9750420AS)
  P2: HL-DT-ST DVDRAM GT51N
  Disabled

How to boot into ubuntu 12.04 which I just installed?

I also find similar post,but I can't figure out what to do next.

How to solve it?

Thank you~
