The problem is that my first partition is Dell Utilities and my other two are for Windows 7, which can't be deleted
yes it can .
get a free copy of the install dvd from Microsoft
wipe out the dell install and reinstall win 7 in a sane manner
that "recovery" partition is just as vulnerable to a virus infection as the rest of windows
as to the arch installer
keep at it .it can be a pain but it is usable
