@Adam... Thanks for your comment...
Ironically, if you take a look to my first post in forum.mandriva, I had exactly the same problem and your suggestion was to use the DVD(Talking about 2009.0 ONE KDE) ... this time I follow someone's else advice and it booted the 4rth time I tried.. The DVD and the 3 CDs go just fine with no single issue...
The Spring ONE GNOME I had to burn it at the lowest speed and it worked but it does not let me use anything, so for me is useless, and md5sume and sha1sum are just correct... however I still give you the credit that it could be a bad burn (I have already burnt some like 10-12 CDs and all went to the garbage can :(
Going a little bit further I iuse the ONE KDE in my wife's PC and it worked like a charm, but when I installed it.... I could never boot... so I just inserted the FREE DVD and it fixed everything...
IMHO, there must be a bug in ONE KDE and GNOME... but I frankly don't think it is a kernel related bug,... as I said before.. the is the second time with ONE.. first with 2008.0 and now 2008.1.
And just to finish, I had never this problem with RC2.... strange, isnt it?
Kind Regards
Luis
