I just installed beta1 on my computer and i also enabled dualboot. i overwrited my linux lvm partition with the befs one.
Then i overwrited grub using the Windows installation disc (bootrec /fixmbr at command line)
Then i enabled dualboot with easybcd.
My computer is :
HP dc5850 amd athlon x2 5000
M/B chipset : AMD RS780 and SB700
Graphic card : ATI Radeon HD 3100
The devices application says that my graphic card driver is not supported.
Youtube videos are very slow and the mouse cursor slows down every 5 seconds.
I think it is due to a bad support of MB chipset driver or graphic card drivers.
