Hi everyone,\n\n\n\nI have been doing some research and it looks like my laptop had a 64 bit chip (its an intel core 2 duo T5750). Can anyone confirm if this is actually a 64 bit chip?\n\n\n\nAlso, if it is, I was wondering what my reinstall options are... Will i need to reinstall all of my software or can I preserve it in some way? I only ask this because I thought ahead when i installed my current version of vista and partitioned my drives in an unusual way, as follows:\n\n\n\nI have to local hard disks, each 160gb, which i will refer to as disk A and disk B wen referring to the physical disks. I have the disk A split into two partitions (named C: and E C: is 30 gigs and E: is 120 gigs. The second disk is only one partition and is called Z:\n\n\n\nI installed Vista to C: (30 gigs) and all of my software is on E: I use Z: for an archive of static data like pictures and music etc.\n\n\n\nZ: will be easy to backup and restore if i upgrade but Disk A (C: and E are another story...\n\n\n\nIs there any way to back up the software installed on E: ?? or even better, can i install Vista 64 on C: while leaving E: alone? It seems like it would not work so well since the registry will be erased?
