I owned 2 notebooks (1 for work, 1 for personal use), The new vaio z series, which did not come with any disc. It does have the recovery partition, of which I can make a recovery disc. But it fills with all the sony bloatware....hence I want to use the dell (m1330) vista recovery disc to install it on my sony vaio, as I want to do a vista clean install. I can always use the vista key on my vaio to activate my vaio Searching on this forum , I found out that the dell vista installation disc does have slight modification done to the vista dvd. So I am asking whtether I can modify the dell oem vista disc to original vista using vlite..
