Install Win 7 on Second Hard Drive First

January 25, 2010 at 12:15:33
Specs: Windows 7
Hello...
I have XP Pro 32 Bit on one hard drive and
would like to add a
second hard drive, boot up in the original Win
XP on the old
hard drive and insert Win 7 disk and choose
Advanced and
will it allow me to then install "7" on the
second fresh clean
internal hard drive? THEN I would make this
my primary in the
BIOS..... and I would sometime in the near
future move
everything to the new huge hard drive, format
the old and then
use the old drive as a storage/backup. Both
are SATA if that
is a needed tidbit. THANKS

Your plan will not work at all.

You would put the drive you want windows 7 on as the only boot drive in the system. You would set your bios to boot the cd first and install windows 7 from a cdrom bootup.

You can not move drives around in a system and expect the OS to boot or still work.

I think it would work. Windows 7 uses a new boot loader similar in some ways to grub. As with most MS systems the "C" drive is relative to the OS and not a true path. When you boot to Windows 7 it will see it's system drive as C and when you boot XP it will see it's root as C. The programs will all work.

There are many ways to do multiboot.

Not sure exactly why you are saying to install from xp.

After you move the drives around it might be that you have your loader on the xp disk. You'd just have to repair it with the W7 dvd.

Worse comes to worse you always have your backed up files.

Here is a sure way. Remove the original drive, install the new one, format the new drive and install Windows 7. After it is running correctly and you have personalized it and reinstalled your programs, reinstall the original drive (you might need to make it non-bootable in BIOS) and transfer your files over. When everything is to your liking, reformat the original drive and do your back-up ASAP.
I did it this way when I built a new system and moved over the HD from my old one to transfer the files and also formatted it as a back-up drive. (though the old one was EIDE)

This is what I did. I have two hard drives in my system. I have Windows XP on C: and inserted the Windows 7 CD and installed onto my D:. The final product was that, during boot, I'd have 30 seconds to pick between Windows 7 and "Last Operating System" (or something similar). I'm currently running it that way and switch to Windows 7 when I want too by simply restarting my computer and choosing Windows 7. Now, when I do this, the files that are being accessed are from D: and not C: (which is what some people here think that this could be an issue).

I don't think willalbert wanted to move files back and forth to save the applications but simply to use a second hard drive with a second operating system.

Am I right?

**EDIT**

After reading this over..I realized my answer might not answer your question. I failed to understand the part where you wanted to make the Win7 your primary. At that point, I have no clue what can be done and I would follow the advice from the other guy and take out your original hard drive with WinXP and make your new, clean hard drive the primary while installing Windows7.

Can anybody answer what would happen once the WinXP is reinserted as Primary? I think it'll boot fine but to access Win7, you'll have to unplug the hard drive everytime?

Absolutely! Essentially, what you end up with from the above config is a dualboot, which you can preserve & just choose what OS -- between XP & Windows 7 -- you wish to load at boot & trust me, it will come in handy from time-to-time.

"... and I would sometime in the near future move everything to the new huge hard drive, format the old and then use the old drive as a storage/backup. Both are SATA if that is a needed tidbit. THANKS"

If, in fact, you end up doing this later; you would need to run fixboot & fixmbr to rewrite the boot record so you can boot into Windows 7 after you wipe the disk containing XP.

Here is my take.

On a new system that allows a boot order choice.

When bios selects the boot order the installers tend to mark the partition active. Old rule was only one active partition but basically you have drive 0 and drive 1 both active but selected by bios. Each when selected in bios are viewed by OS as the actual boot drive (first in chain with active) and the OS and boot files will be loaded as normal. XP will remain totally correct on Drive 0. W7 will remain totally correct on Drive 1. All works fine as long as Disks stay where they are and bios is used to select boot order.

Now you could bork it all up by letting MS do what it wants. I run a lot of Alt OS's and I have to let bios select work. When I remove the drive or change OS's no other install has changed.

All you folks have great suggestions/advice. I thank the lot of you
and now must FOCUS and re-read and digest and ultimately
decide on the not necessarily best (as they are all best) but
preferred by my future needs method. This "Tom's Guide" Site is
to be applauded and has my unequivocal gratitude as do all my
respondents. Any additional comments are also welcome as I
yet at this moment have a bit of uncertainty choosing the way for
my switch to "7":"Two roads diverged in a yellow wood, And
sorry I could not travel both..."
