[ubuntu] Installation on UEFI

$

I have been trying for 2 days to install ubuntu 13.04 next to windows 7 on this computer . Im not that tech-savy , and a totaal linux noob . Ive had a huge amount of help on the IRC but there also we seem to got stuck so i thought to ask it here .

This pc is fairly new , specs are:

MOBO: Asrock 880gmh/u3s3
AMD FX8120 -8core 3,1ghz
8gig Ram DDR3
Amd Radeon HD 6800 series graphics card

Important : my dvd drive is broken , so i do everything with bootable USB drives , i used unetbootin to 'burn' the iso. images to USB .

I got one 120gig SSD drive , and a secondary 1TB (sata 2 i think) drive .

So first i clean formatted everything , installed windows (NTFS) on the SSD as i will still be using windows mainly for games , and sometimes for other more heavy applications if i cant find a way to get it working under Ubuntu.

The 1TB drive is partitioned as following :
60gig for Ubuntu (ext4 , mount point / )
675gig for all data (NTFS so i could access it with both OS?)
195gig for what i call 'input' , NTFS , so internet downloads , torrents , everything that comes into the pc (in the idea to reduce infection risk if something goes wrong)

First i had some issues with the graphics card (flashing purple white screens) ,and after some IRC rescue help , i figured out where to put the nomodeset to get that working already.

Went into the install menu of Ubuntu , choose 'something else' .

There i made / it was following setup :
/dev/sda
/dev/sda1 = NTFS 104mb windows 7 (loader)
/dev/sda2 = didn't say anything but i assume here is Windows installed

/dev/sdb
/dev/sdb5 = swap (4gig , i didn't do this at first , but i got the warning when clicking continue . I dont know if its necessary , but i dont mind sacrificing 4gig to be sure)
/dev/sdb6 = ext4 Ubuntu 13.04
/dev/sdb3 = the data disk NTFS
/dev/sdb4 = the input disk , also NTFS

Boot loader was saying /dev/sda , nothing more.

So continued the installation , also entered my wifi password (got a wireless network card in this desktop) , let it run and download some extra packages. Ok.
When it was ready , it asked me to reboot - yes - and then i got these really trip blue vertical lines on a black background , with 4 small redish squares on it .
It seemed to be stuck there so ive done a hard shutdown .

Changed the boot priorities back to my hard drive , and there i noticed the first strange thing , the bios (or UEFI) didn't seem to list my secondary HD in the boot priority menu , but i was visible in another boot priority sub menu (dont know anymore what it was called , can check it after i write this) . There i could switch it with the SSD drive , and then the secondary hard drive would show up in the boot priority menu , but then the SSD wouldn't.. still very confused about this , as in the past it showed up all devices it could boot from.. I can make a photo / video from it with my phone if needed.

Anyway , no matter how i put these settings unless it was the USB drive as first boot option , it would go straight to windows , no asking wich OS i want to start.
On recommendations in the IRC , ive re-done the install process (same way) , again got those strange blue lines at the end , but now they disappeard in 1 second and the pc rebooted . Again changed boot priority to hard drive , nope straight to windows . Also tried putting the 2th hard-drive where ubuntu is installed as first boot option (like i explained in the previous paragraph) , but no choice , straight into windows.

Only at this point i thought about mentioning the UEFI setup bios thingie in the IRC :rolleyes:, and they told me that probably the issue is in there , and they didnt know how to deal with this.

So thats where i end up here . :lol:

What options do i still got ?
I finally , after years of doubting it , decided that i want to give ubuntu a shot , and its probably worth it i believe that , but i have to get it running first ofcourse ](*,)
