linux is great, but let’s face it: i still need windows. i messed up my dual boot long ago, and what’s the point of switching between the os anyway. so, here’s the no-compromise solution: run windows inside of ubuntu. how nice
here’s how:

first, install some dependencies:
apt-get install build-essential
uname -r
apt-get install linux-headers-’you kernel version’
apt-get install gcc-3.4
apt-get install g -3.4

then install the vmwareplayer:
download the player
tar xvzf VMware-player-1.0.0-16981.tar.gz
cd vmware-player-distrib
export CC=/usr/bin/gcc-3.4
./vmware-install.pl

finally, create your virtual machine at http://www.easyvmx.com/, save it on your disk.
insert your windows cd, lauch the vmplayer (/usr/bin/vmplayer) and point it to your virtual machine. enjoy.
