Dual boot Windows 8.1 + Ubuntu

I have been using my computer with Windows 8.1 for about 2 months. Now I decided to install Ubuntu 13.10 alongside Windows, basically to dual boot. I got myself out of Windows, and booted from my little pendrive, where I had GParted and I shrank the Windows partition. I made it 100 GB smaller to make room for my Ubuntu partition. I made a new partition for Ubuntu with Ext4 filesystem. I also made a little 1GB partition for swap.



So now I basically have like:



sda1 is Windows Reserved



sda2 is Windows



sda3 is Ubuntu




sda4 is a Logical Partition (or extended? hm, anyway:)



sda5 is my swap.



It is all very nice and OK until this point.



When I rebooted, I was not prompted with system selection. Instead, my computer booted straight into Windows. I made a little research, and found EasyBCD to dual boot. I added an entry for Ubuntu on sda3 with GRUB2, and tried to boot again. Now I got a prompt, but when I chose Ubuntu, it gave me error that is couldn't find "AutoNeoGrub2.mbr" or something like that. So I continued searching forums, and decided to install GRUB manually. So I booted my Ubuntu LiveCD, and installed GRUB in terminal using



mount /dev/sda3 /mnt


grub-install --boot-directory=/mnt /dev/sda


After that, I rebooted, and got a GRUB screen. But it wasn't a menu, just a command prompt, and I did not know how to manually boot with it, perhaps I couldn't do it anyway. At that moment I was desperate, because I couldn't get either to my Windows, nor my Ubuntu. I tried many things with my Windows install disk's recovery cmd, and finally got my MBR and bootloader back, and now I could get into Windows as I am writing this. But still cannot get into Ubuntu, and I don't understand what is the problem. Another thing, now for some reaseon System Reserved partition shows up in explorer, what causes that? :O



So that is basically it, could anybody help me get into Ubuntu?



Thanks in advance!
