I'm trying to install BT 4 R2 onto my Sony Viao VGN-NR21J laptop.

It has a 500GB drive, with Win 7 64 bit installed (have tried both 60GB partition and full drive).

When I boot BT from the DVD and try to install via the install.sh it doesnt show my current Win 7 partition.

I've tried numerous ways of trying to format the drive, a 32bit Win 7 install, but BT still not seeing the Win 7.

many thanks in advance
