Is it true that on a dual boot system, any applications must be put on the partition of the operating system that will use them. This is what it says on the Microsoft website
Yes and no. For instance, you can't dual-boot Win98 and WinXP, install a program on the partition that contains WinXP, and then run the program from <i>within</i> Win98, simply because it is visible on the other partition. Operating systems and the programs installed in them must be kept separate. Two operating systems ... two Registrys ... a copy of the program you want to use in each one.
However, this does NOT mean that every program you choose to run MUST be within the system partition.
You can actually have up to four partitions per hard drive when running Windows.
Two examples:
Two hard drives, with two partitions on each.
Hard drive 0 contains Win2K on the primary partition.
Hard drive 1 contains WinXP on the primary partition.
All partitions are NTFS.
I install Norton Anti-Virus in the Win2K system partition.
If I wish to use the program while running WinXP ... I must install the program again in WinXP. I cannot boot into WinXP on hard drive 1, access hard drive 0, find the .exe of the Anti-Virus program in Program Files, and run it. This is because there are no entries for the program in the WinXP Registry.
Trying to access a program in this manner can cause anything from Master Boot Record corruption, to bad sectors in the file system.
Instead, to run the program in WinXP, I'll have to install it again.
And that's how it works. It is a cardinal rule that you do not access programs across platforms when dual or multi-booting operating systems.
Example 2:
Hard drives are set up as mentioned above.
For this example, let's assume my drive letters are:
(C
and (E
-- Hard drive 0.
(D
and (F
-- Hard drive 1.
CD-ROM - (G
Two partitions per drive.
I boot into WinXP, which is on the system partition on the slaved drive (D
. I decide to install Castle Wolfenstein, but I'd prefer to place it on another partition.
I have decided that personal files and extra programs I'd like to use in WinXP will go on the (F
partition, since both partitions are on the same drive. Helps keep things organized.
I create a folder on (F
called Games.
I install Castle Wolfenstein, and during the installation, choose to place it into a subfolder called F:\Games\Return To Castle Wolfenstein.
This game will now run just fine in WinXP, as this was the operating system that was running during the game installation. However ... you should <i>not</i> try to play it in Win2K, such as by creating a shortcut to the .exe on the desktop.
Interestingly enough, you can now boot into Win2K, and have a choice of whether to install the game into the primary partition that contains Win2K, or the second partition on hard drive 0, or install the program again into the very same partition with the Game folder you created in the first place.
However, because some programs cannot be updated with patches twice in a row, the last option is the weakest, and the most likely to cause problems. For instance, if I install Castle Wolfenstein twice in the same Games folder, with the same file path, and then patch the game from within WinXP, the patch won't work from within Win2K, as the game is already updated.
So ... my recommendation is to install a program twice, if you wish to run it in two operating systems, with a different folder or partitions chosen for each program installation ... if you need it for each operating system, or wish the program to be accessible in each operating system.
Does that make sense? LOL!
