Hi, I'm hoping for some advice here before I go on install Win7 on my MBP by bootcamp and also what I can do after installation if something doesn't work out for me. I have made a thread before concerning this and a few pertaining Win7 on this platform. So I have a retail Win7, and it is installed on my old desktop PC, which is in the basement crawlspace collecting dust. I have been using this Feb 2013 15' rMBP for awhile now and I have finally gotten a time today to maybe install a big game using Win7. I'm still unsure. The Win7 retail copy I have is still installed on my old PC, but I haven't turned it on ever since I got this laptop. The desktop is just waiting to be reformatted -- and the reason is I'm not sure what the proper way is to reformat that because I am planning to sell it (is this unlikely?). Now if I install it here on my MBP, would my OS be voided its function because I violated the law or something? I want to make sure that I don't break my software because of it, and that it will be 100% using it FOR NOW on my MBP without using it on the PC whilst having it installed on there. I hope you can understand. Also, for gamers in here who play with the MBP, how long in terms of hours is too much for the laptop? I have the 1GB GT650M, 2.4GHz i7, and 8GB Mem, and 250 SSD, SanDisk lol. Any other warnings that I should know before bootcamping Win7 or mistakes that I could get or am I just thinking too much? Hopefully I'll have everything covered. Any wisdom is greatly appreciated. Thank you!
