Dual Boot XP and 7 from two HDD.

Short answers: Yes, up to you and your budget, no problems at all.

Slightly longer story: if I dual-boot, I always do it with separate physical hard drives. And I keep all my data on yet another hard drive. It is often recommended to remove the hard drive with another OS while installing the new one, but personally I've never done that and I've never had any problems. My motivation to keep things separated like this is simply that if a hard drive fails, then all partitions are gone, while other hard drives are not affected at all.

As to best hard drives - there are lots of brands, people prefer different ones, as of recent I have Samsung (see my specs), but at the same time nowadays it seems that it's best to put the OS on a SSD, if you can afford it (they are getting cheaper and cheaper though).

As to possible hazards - I don't know any. Of course something may go wrong and you can find lots of questions on this forum about various issues, but issues come up in single-OS systems as well, I don't think that a dual-boot system is more prone to problems.

Good luck!

While we're at it, could you guys comment on why do you insist on unplugging other hard drives while installing new OS and what's wrong with using Windows boot loader as opposed to the BIOS menu? My experience with this is probably limited, since I am only dealing with my own machines, but I've never had any problems by simply installing another OS on another hard drive and then using Windows MBR to choose the OS.

When you recieved your Fujitsu, do you recieve the Windows 7 & Win XP downgrade DVD's.
Two Hd's is the best way.

When you no longer need the two OS's, just unplug one HD, no need for all the hard work going back to one OS.

The prime benefit of having OS's on two separate HD's is their independence including the ability for either HD to come and go as you please.

If you leave both connected during install Win7 will configure a Dual Boot which interlocks the HD's requiring major surgery to remove one, hence defeating the benefit of full independence and instead making them interdependent.

That said, it is up to User preference and we are always here to help extricate one OS from the other if needed, and do so almost daily.

Interesting Win7 tidbit: After release was the busiest time for removing Dual Boots as dozens of users decided to abandon XP or Vista almost immediately after installing Win7. We could hardly keep up with the traffic and it's a big reason we use automated methods here to this day. It is easier for the average user to mark Win7 Active and run 3 Startup Repairs than to use Command Lines and bcedit.

I am trying to install XP on a separate HD, on a computer that has Win7 pre-installed. I disconnected all HD's except the blank Sata HD that I want to install the WinXP on. Problem is that it stops just after it says "Setup is starting windows" then I get a blue screen of death...(see attached pic) I have done a chkdsk /f as the error screen recommended but its still gives me the same problem/error screen.

Why does this happen, and how do I over come it?
