I am a fan of Ubuntu products and not the newest in dealing with its Desktops and servers, but i have come across a huge problem. When Ubuntu 13.04 came out and claimed it supported UEFI, i immediately got it for my laptop, and Asus K55N. I tried to install it by manualy selecting the swap, BIOS, and root partitions so i can keep it organized with Windows 7 Home premium. So after it finished installing, when i rebooted, it said there was no boot-able device installed. I assumed it was because of UEFI so i disabled it and still there was no booting option. I then looked on-line and tried Boot repair on the LiveCD but none of it worked. I am out of ideas and i need help. If anyone can find a way to fix this without deleting Windows 7 or its files, i will be grateful.
Here are my partitions:
/dev/sda1 ntfs 172854MB Windows 7(loader) (my C: drive)
/dev/sda2 ext4 296351MB Ubuntu 13.04 (my D: drive)
/dev/sda3 ntfs 26843MB Windows Recovery Environment (loader)
/dev/sda4 biosgrub 148MB
/dev/sda5 swap 195MB
again any help would be appreciated, thank you.
sudo grub-install /dev/sda4
