yes, my Bios is up to date.
I have tried external USB mouse (a simple one from Microsoft and a chordless one from Logitech). The notebook doens't have PS2 connectors. Haven't tried an external keyboard, I don't have a USB one.
I got in touch with Dell last Friday...they should call me today, but I am not seeing it.
As I got informed in other places, it could be related to the MBR of the disk.
When you install Ubuntu, it will change the MBR with its bootloader, GRUB.
It is knowed that Vista does not like different MBRs, so it would not install.
Do you know anything about it?
How can I revert the MBR to the original (Windows) one?
