Windows 7 BootMgr missing (Installation)

In short(long), I have just just upgraded the computer with more RAM (Corsair XMS3 DDR3 1333MHz 16GB KIT CL9), an SSD (Kingston SSD Now 200 V + 120 GB) and a standard SATA disk of 1.5 TB. The idea is of course to install Windows 7 on the SSD, and games and such on the larger disk. The problem is that something causes trouble with the installation of windows 7 (pro).

What I have tried (and what has gone wrong) are as follows:

Booting from the windows disk and installed SSD. Only SSD and DVD plugged in. The installation crashes in an early stage (before the first normal reboot) with the result that the screen goes blank (as if it does not receive the signal, statusLED turns orange, normally green) and nothing happens.

Booting from the windows disk and tried to install Windows on my 1.5 TB drive, it being the only disk connected. The installation crashes in exactly the same way as the previous one.

I started windows installation from my previous (working) Windows installation and installed onto the SSD. The SSD, DVD and SATA disk with the previous installation were connected. The installation proceeds with the restart, then the error message that the boot manager is missing comes up. The BIOS boot-order is DVD, SSD, SATA (win).

In the first two cases, it does not matter if it's an SSD or an old-fashioned HDD, suggesting that there is something wrong with the installation disc, maybe. But in the last case, it seems that the installation is going fine, until it complains about the lack of boot manager. If I manually boot from the installation disc the installation restarts (and crashes just as before a little bit in with the screen turned off, I have tested).

I have also tried to change the RAID mode in BIOS from IDE to AHCI ending up with the same result.

The motherboard is a MSI 770-C45. BIOS is updated to the latest version.

Anyone have any tips on how I should behave in order to successfully install Windows 7 Pro on my SSD?
