Hey, I'm relatively new to the whole Lite installation bit, having only recently discovering when I needed a cut-down OS for my Eee PC... I managed to make a great nLite install for it, and had no issues. So let me first say thanks tons for that. Anyway, now that I love this Lite business so much, what I really want to do is strip down my main PC's OS (Vista), and also hopefully allow it to double-boot into XP (where I would use the XP install purely for gaming). Does anyone have any specific recommendations for this, like using a single drive with two partitions, or two entirely separate hard drives? And if I install on separate hdds, should I have them both installed during both OS installations, or should I install nLite say first onto one, then switch the hdd out and put in another, install vLite, then install the 2nd one back in? Also, in either case, is any order preferred? Will vLite load from within XP, as a normal Vista installation would? Based on my own past experiences with the OSes, I think this would be my game plan right now: After creating my nLited and vLited ISOs, I should install nLite onto a fresh hdd, and create a small partition that is only slightly bigger than what is required for the operating system and bare system apps that I would use simultaneously while gaming (xfire, fraps, etc). I would then plan on simply installing my games onto another physical hdd, to increase read speeds while playing. Once I have nLited XP installed, with all required drivers for my PC, I stick in the vLited Vista burned ISO, and install Vista from within XP. This guarantees that Vista sees XP on my hard drive on a separate partitions, and thus would give me the easy 'select OS from this list' bit during boot so I can choose easily whether I am gaming or not, rather than having to go into bios to switch between hdds as my boot device as I would have to do if I install on a separate hard drive. (I'm not sure what to do if my Vista installation decides to be one of the picky ones that doesn't work properly from within XP...) Then from there I do the usual vLite Vista install, install missing drivers, etc, and I'm good to go. How does this sound? Am I missing anything, and if so, what? Lastly - sort of unrelated to anything 'Lite' related, but I have done a dual boot between non-Lited versions of XP and Vista in the past, just to test Vista out. However, when I did this, one time soon after the installation I booted into XP and did a bunch of file organization, including moving 600gb+ of video files into a folder on the same hdd/partition (single partitions on all drives, multiple hdds, OSes installed on different hdds, Vista and XP did not see each other) as the Vista installation, then I later booted into Vista only to see that any sort of files or anything that I had moved onto the same partition as it were entirely gone. Going back into XP they remained gone. Can anyone explain how/why this happened, and how I can avoid it again in the future? Cheerio, thanks for the help anyone/everyone. Sorry for making such a long first post, and for possibly being nooby if I am anywhere.
