Hey I got a WD Raptor 36gb Sata harddisk which i've been wanting to install for some time, but never been able to make it work. My Floppy Disk Drive isn't working so i've been looking for other solutions. I came onto nLite about a week ago and started trying out the program. I made a bootable iso which included the Sata drivers and settings so i wouldn't have to do anything when installing windows. Then i plugged in the Sata harddisk (my other harddisk is a normal Pata), And formatted my C:\ drive and made a partition on the Sata harddisk. So the problem is: It says the partition can't be used for installing Windows on, and in the menu all i can do is go back to the partitions menu. Furthermore it says that it needs to copy 190000Mb's (that's 190gb's!) of files to the drive i wanna install Windows on. Which doesn't make any sense whatsoever, since the cd only takes up around 600mb's of space. So where did i go wrong? anybody got a good idea of where it went wrong? I'm sorry if this has already been brought up before, i couldn't find anything on the search menu. Thanks for your help in advance.
