Are there any arrows to click which will move an item up or down in the boot sequence box?

it's confusing, but on mine, you can click on one of the drives, then click an arrow to move it up or down in the list.

There's no settings in bios for changing the order of devices to try to boot from?

Or, they can't be changed?

Post what bios version you have, maybe that will help.

If I go to boot sequence and press on the select butten it don't do anything and my bios version is a02 07/02/09

No I get kicked out of the menu in a mili second

can you try reset cmos jumper on motherboard so you can reset bios to default setting?

I noticed there are newer bios (A07 I think), maybe worth a try if you can't get it working.

Could you share a copy of the invoice (image or PDF) so that I can validate the information for you?

Do you maybe have a link to that? 

If I look on my motherboard ther is only a jumper with 2 pins is that the richt one? 

To reset CMOs jumper you move the jumper from PSWD to RTCRST on motherboard as shown in the link pic, wait 1-2 min, move the jumper back to PSWD.  (If you left jumper on RTCRST pc would not turn on).
