Install updated drivers

I've found out there's newer drivers for my Studio laptop for webcam, wireless, etc. I updated the BIOS and it went fine. My question is do I have to uninstall current driver before installing new one? On Dell web site, they only give general instructions and don't mention this. If I install new driver over the old one, will I have 2 versions and can go back (in device manager) if the new driver doesn't work as well?

Btw, I can't find any restore DVD. There's a hidden partition and one labelled "recovery". In case Vista crashes and I can't boot into it again, how can I access the recovery partition and restore from that? The DVD they give only have installed software and drivers. My Lenovo has software to burn recovery DVDs. I can't find it on my Dell.

 

I believe you can get the recovery software from Dell's website. Will post the link if I find it again.

 

I've found the link to request restore DVDs here:

You can also access Dell restore program in the hidden partition by hitting F8 and choose Advance Boot Options. But if your HD crashes or you install a new one then the recovery DVDs are more useful.
