I had to uninstall Boot Magic, even although it was not active, before
I could install VISTA from the DVD, regardless of whether I booted from
the DVD to make a dual boot or whether I tried to install from within
Windows.
I got an error message that it could not find either ntdlr or bootmgr
according to which I tried -- forget which way round 8
I haven't tried to see if it will install afterwards ......
Despite the Restore "feature" I find it quite useful to be able to
access the XP Pro files from within VISTA during the testing and
transitional period I'm in.
If it were for general family use I might be concerned because way back
in the old-fashoned days a friend managed to dual boot WIN 95 and
WIN98SE without hiding the inactive drive and he kept on doing things
to files in the wrong partition.
But we experts knopw better, don't we? <g>
