Problem with bootable devices (new made mainboard with win8)

Hello, Just took a new computer: Acer TravelMate P253-E with Windows 8 inside. First of all I want o install win7. Inserted dvd with win7 setup and tried to enter boot menu or BIOS setup at the start of just turned on computer. Tried all combinations from (esc, f1,f2....f12,del) nothing works also tried alt+esc,f1,f2... same with ctrl - all I found was win 8 automatic system restore, without any options. After that i just took the HDD of this computer, putted inside another and deleted all partitions, created new one and installed win 7 without problems.. didn't though that the main problem starts here: inserted HDD with newly installed win7 to my Acer TravelMate and i'm getting "no bootable devices found, press any key to continue" no chances to enter any setup or to boot any setup from usb or dvd.

I tried to mention my problem as accurate as possible, waiting for an answer. Thanks :)

NOTE: Check your manufacturer's uEFI/BIOS firmware manual for settings.

Make sure CSM is ENABLED, & set to UEFI boot.
Technical Note: UEFI BIOS vs. Legacy BIOS - YouTube
