Thanks guys for putting my mind at ease.
I found this little tutorial online on how to install VL:https://vector.ecosq.com/ic/HowTos/HowToBook/ChapGetStarted/guiInstallation#secInstall
However, it has a few mistakes and also is a bit lacking in detail. Could I have your advice please on what would be the best choices to make? Things like the partitions (I set 10G for the machine, as you recommended), formats, what packages and bulks to install, etc?
I have a ThinkPad T400s - core duo 2.53GHz and 4G RAM, but I really want the install to be lean and fast.
