Hi folks I am a total newbie to Windows having been a Mac user all the time. My company recently purchased a Acer Ferrari 4000 and it came installed with Windows Home, which was loaded onto the C drive. The 100GB HDD is already partitioned into 50/50. Now this is where I need your help please. and would appreciate your patience in talking me through this (the tech support at Acer isn't any help at all and Microsoft..well I haven't contacted them yet). I've bought the Windows X-64bit OS for installing onto the Ferrari. It hasn't been installed with any other programme or antivirus etc. So : 1) do I install it on the C drive and leave the Windows Home edition alone, or 2) Install it on the partitioned D drive? 3) or should I simply do a clean install of it and discard Windows Home Edition (I would personally prefer if it were Windows Pro instead of Home, but since I don't have that luxury to get both Pro and Pro X-64, I've to make do... 4) How do I do a clean install, if that is the recommendation? 5) will it remove the partition and how do I re-create a partition if it is no longer?) 6) How do I do a clean install and maintain the partitions? 7) Should I install x-64 into the C or D drive? 8) will the x-64 recognise the items that are existing in the Ferrari such as the modem, the Lan, ethernet, DVD -burner/player etc etc *Anyone familiar with the Ferrari - are the items 64bit ready? 9) Where do I find drivers for XP-64 bit if some drivers are missing? Ok I think these 9 questions will suffice for now. I know how to troubleshoot my Macs but Windows is just beyond me - which folder the preferences or drivers go etc.. As I mentioned, please have a little patience with me as I only have 1% Windows knowledge. So don't expect me to know or understand for example, what Bios or Ping or etc means. I've heard of those terms but have absolutely no idea what it means. Thanks very much in advance. Cheers all
