Welcome to Mint sonics
A couple of questions
Do you have two RAID configurations?
If so which RAID (0 1 5 ...)?
But you write
(i installed it on noe of the 500GB).
I suppose noe is a typo for one and that doesn't indicate RAID.
You could possibly overcome the blue screen by using the "vesa trick" described in the howto:

Not that I understand why the video driver could be a problem in the one but not the other case, but it's worth a try.
It could also be that there is a nasty error on your harddisk and the install is corrupted. If you changed a partition in any way on the disk you installed on the partition table may have gotten screwed up - that happens.
What else do you have on the disk you installed Mint on?
