Some months back I used wubi to install ubuntu on an hp laptop with vista. After not using it for a month or so, I loaded ubuntu and installed many updates (including kernel update). Windows boot manager loads without any problems, and I can boot to vista without problems. However, if I choose ubuntu, the screen briefly flashes
Try (hd0,0) : NTFS5
and then goes to black. I never get to the kernel image selection screen.
