Running a dual boot Win 7 and Osuse 11.2 with opensuse installed on extended
partitions. 

Given the age of my current OS(11.2) I decided to install 13.2, to get updated
software and access to the Tumbleweed repo.

I downloaded the iso, wrote it to a dvd and restarted my current dual boot
laptop. I completed the fresh install in the same partitions used for 11.2, but
the install had an issue at the end with loading Grub into the MBR. Despite
retries or even ignoring the error, the laptop boots and I am left with a blank
screen with the word GRUB on it.

I wait a few minutes for a menu but nothing. Enter does nothing.

I reinstall from the DVD, but now as an upgrade, run through the entire install
process and still get stuck on writing the boot code.

I cannot even get to the Windows OS

I realised te problem might be the btrfs.

I reinstalled as a fresh install into the Linux partitions but changed the file
systems to be formatted from btrfs to ext4.

Install completed and I was presented with a boot menu which included an entry
for Windows and another for opensuse. Selecting the opensuse option took me
into the new OS. :))
