Hey,

Ok so i followed all the steps in the guide (dual booting xp with vista pre-installed). The xp installation was successful so it worked when it booted the first time when i only had xp. Then I used Vistabootpro and installed a vista bootloader. I restarted my laptop to check if everything was there. I went on vista to make sure nothing went wrong and restarted again. I selected windows xp and it says:

0xc000000f The boot selection failed because a required device is inaccessible

can anyone help me with this?
please help =0

Thanks,

PS: i own a Pavilion dv9205us
