Dual booting with two different hard drives?

Actually, theres no such thing as Master/Slave in SATA, since each drive is connected to different channels, whereas IDE can have two drives per channel. What you need to do is determine which channel each Operating System|OS is on, via your Device Manager in Microsoft Windows|Windows, and then have your boot config file point to each partition. You can find this setting by right clicking on My Computer and selecting Properties, the Advanced tab, then Startup and Recovery.An easier way, if your motherboard supports it, would be via a boot loader in the BIOS.

I can do this on mine by pressing the F* key when the system starts. Your system may or may not have this feature.

I'd guess you might be able to do this. You'd probably need to have both drives connected, probably the drive with XP as master and the drive with Microsoft Windows 7|Windows 7 as slave. On the XP drive, you would modify the file BOOT.

INI in the root directory so that there's an entry describing the other Operating System|operating system, and also enable the option which shows the boot menu for however many seconds. The entries let you specify the drive as well as partition, so I would think that if the Windows 7 drive is drive #1 (with your XP drive being drive #0), you could possibly place an entry similar to this:boot loadertimeout=30default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWSoperating systemsmulti(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetectmulti(0)disk(1)rdisk(0)partition(1)\WINDOWS="Microsoft Windows 7" /fastdetectBelow I've linked a guide on Microsoft's site specific to the BOOT. INI file.

If you've got one SATA and one IDE drive then they won't both be "masters". I always use IDE drives on "cable select" anyway - much easier! But yes, they can both be in your system and you can boot from any of them.

I have a similar setup - 1 IDE drive (Windows XP) and 2 SATA drives (Microsoft Windows Vista|Vista & Linux). I always boot from the Linux drive first, which then loads the GRUB boot loader and I can opt to boot into any Operating System|OS, or just wait for the default to boot. If you don't want to use a bootloader (there are others, but I think GRUB is the best), then you should also be able to use your BIOS to select which drive boots first.

No you wil have to move on Operating System|OS to the remaining master as you cannot run a Computers|computer with two msters it wil not boot righ.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
