Hi All....Help! I have been all over the web trying to find some answers and you are the closest I have seen for real help. Have an older Sony which upped from xp to win 7 ultimate over 2 years ago. I don't remember if I did it as an upgrade or formatted the drive and did a fresh install. I think I did a fresh install because I had to go and retrieve all the drivers. No problems until this week. It is my son's computer for school. Since it is old, last year I purchased an IBM Intellistation which I intended to load linux and keep his current drive with his current software and files as a secondary drive. Was going to do it this winter but had some major health issues. I don't want him to loose his current programs under windows, so was intending dual boot. I know it sounds confusing. I have been recovering myself, so was planning on doing the transfer in a month or so. I am not sure what I should do now. So my question is if I go ahead and push to get the IBM going with Linux (and the wine for the windows) and a windows 7 on the primary boot drive as dual boot, will it matter if the windows on the secondary drive is working? I think it would not matter at all. But, I don't want to mess up his stuff. Yes, I intend to clone the current drive to be sure things are safe. The invalidation mess came up early this week so I have less than 25 days to do something. I did this with mine and it worked fine. I loaded a new windows 7 on the primary and put the old drive in as secondary and can run the old programs without reinstalling them on the primary drive. But...my old windows 7 was working fine when I made the move. The keys for all are OEM keys. Any thoughts? Thank you for your help in advance.
