grub text in black screen

hello to everyone,


I started with openSuse 2 months ago coming with my pavilion dv3 with windows 7. It took my time to realize that
I can not install linux-opensuse if the disc is dynamic, so I use testdisk to convert dynamic disk to basic disk
as seen in Linux Mint Forums • View topic - Warning: Don't install linux on a Windows Dynamic disk. After having plenty of unallocated space in my
hard disk it was no problem to install opensuse 12.3, this time was quite straight forward. I used EasyBCD 2.2 to
deal with Windows bootloader following this page, Dual-Booting Windows and openSUSE.
So everything was all right until I updated opensuse, it was around 70 packed.
Now, all I get it is a grub text in a black screen. To recall that I had to do the installation in safe mode (F5).
I have reinstalled opensuse without making or deleting any partition, just again with the dvd.


I would appreciate any advice to solve this situation.
