I need some advice...would this be a good idea:hard drive 1 -- Vista64hard drive 2 -- WinXPhard drive 3 -- FSXNow, I wish too boot in either OS--is this method workable:use BIOS to switch the boot drive.Or, are people using boot menus and the like?I want each OS to not know the other is there. Completely independent operation. That's my goal. What is your advice on the best way to implement this...thanksRhettAMD 3700+ (@2585 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2gb Corsair XMS 3-3-3-8 (1T), WD 150 gig 10000rpm Raptor, WD 250gig 7200rpm SATA2, Seagate 120gb 5400 rpm external HD, CoolerMaster Praetorian

I have 4 OS to boot upon startup1 XP FS20041 XP FSX1 XP Games1 XP Apps etcYou need either more than one harddrive or partitiom the drive you have.What I do then is go into BIOS and change boot device to CD, insert XP and install to whichever drive you wish. Repeat for further installations onto different drives.I have a partition C: of approx 2gig. This contains swap file and boot.ini etc which contains a list of your multiboot OS and the partitions/drives that each OS resides on.Graham

I have 3 hard-drives and a triple boot on a Boot Menu1. Vista2. XP and all my development software3. XP and only FSXhttp://www.syschat.com/dual-boot-vista-xp-...ready-1946.html"Not knowing the other is there??" Well they don't run concurrently, so you can only run the applications that are installed with the current OS, but you can get data from each of the hard-drives no matter which OS you've booted into... which is an advantage. RegardsJim

Even though I have 3 hard drives, I use ONE hard drive with multiple FOLDERS. Each FOLDER with its own full system, XP, XP64, VISTA64.To use any of those systems, I just open that particular folder ONLY. Works great!!! If you only have ONE drive, you still can have multiple bootups.Abe
