tears of the river

Hey guys,
I have tried to dual boot Ubuntu 13.10 (64-bit) to my cousins laptop, acer aspire E1-571G, which already contained the pre-installed windows 8 (upgraded to 8.1). The first of many problems to come was that an error appeared saying:
APAP CDROM: MATSHI TADVD-RAM UJ8C0 has been blocked by current security policy
I was quite confused as this error as upon searching about the error it meant that the secure boot was blocking the cd when it shouldn't because as far as I knew the newer versions of ubuntu didnt go through these problems. Anyway the search results all said to disable secure boot. There were a number of tutorials about how to do that however none of them worked because as can be seen by the attached picture there is an option of secure boot however it can not be selected or altered.

so the forums said to change it from uefi to legacy. So we did that and the installation came up. So we then followed: http://www.everydaylinuxuser.com/2013/09/install-ubuntu-linux-alongside-windows.html we had already 'disabled' secure boot, and fast boot and had a working boot able disk so we went on through the installation we had partitioned 62 GB of free space from windows for Ubuntu and hence we used that. We gave 30 GB to mount point: / , 16 GB to mount point: /home, 16 GB to swap area and 200 MB to Reserved Bios boot area as it said to put some for boot.
We then installed it successfully however when booting up there came no option for changing in between the sytems. As when it was set to legacy it would boot to ubuntu and on uefi it would load into windows 8.1 so the forums said that we should run boot-repair however when it finished it gave this:
249098
We then set it onto uefi and boot it then we got the error
Windows boot manager has been blocked by current security policy
upon pressing ok we get:
HDD: has been blocked by the current security policy
when we which to legacy and try to load up Ubuntu we get:
error: file '/boot/grub/i386-pc/normal.mod' not found
followed by grub rescue prompt.
I have no idea what to do now and am too scared to experiment on it so i decided to post to you guys.
NOTE: as far as we know we cant load to either OS however we can load to live disk through legacy and we used live disk to do boot-repair
