HP DV7 amd64 Turin x2 RM-70

HI,

My laptop, HP Pavilion DV7, is an AMD Turion 64 x2 dual core mobile RM-70,
with 4G RAM and 250 G HD. I installed Ubuntu or Lubuntu from 6 till 12.10.
Since the recent Ubuntu/Lubuntu constantly crash, I want to change to
Debian. I installed 32-bit Debian 6.0.6 without any problem on Dell desktop
using net installation. However, AMD 64bit can't boot using amd64
netinst.iso, the install menu never show up, only black screen. I google
and can't find any meaningful info, hopefully the experts here can help me.

Best,

Tiandao
