Windows 7: Dual boot win7 x64 and winXP x86

07 Mar 2011   #11

Windows 7 Ultimate x64 SP1

I skimmed and didn't see this mentioned, but since you have Windows 7 Ultimate, download and use XP Mode. It will be completely free, will accomplish what you want, and won't involve messing with boot loaders. Dual-booting has largely been replaced by virtualization, with one of the main reasons being that the host (primary) OS is left alone.

Windows 7 x64 Ultimate

Thanks for all your help - much appreciated.
All these different methods offered were a bit confusing though.
I've managed to make it work now with a workaround. Its not as I intended, but it will do
What I did was simply to delete the 2nd boot entry with easyBCD. With this I'm now able to just select which HDD to boot from at BIOS startup (pressing F8 gives me a list of all connected devices). So Win7 is now default, and whenever I need to use XP, I just hit F8 and select the XP drive
Surely I still have a mess with all the active partitions and what not, but I'd rather do this than to get myself into more trouble.

Hello again.

Using the BIOS one-time boot menu like you are now using is the preferred method we usually suggest people use, you just said you wanted to use a Windows managed dual boot, I would leave it like it is now.

If there are no other bootable OSs on the other partition(s) marked as active, that can be corrected from an elevated command window using the commands outlined in Option Two #2 of this tutorial.

I;m curious how you were able to get XP on D to boot on its own using BIOS Boot Menu since it has no System Active boot files according to the screenshot. You may need to repair its boot files if you try to boot it without Win7 plugged in.

The risk with stray data partitions marked Active is that during repairs the System Boot files will be derailed to one of those partitions, but it is unlikely since they fall after the two OS partitions and the installer looks for first Active partition to place boot files.

But be sure to unplug the other OS HD if you repair one.

You are correct, you have a horrible mess, let's do this one step at a time.

The flag "Boot" is the OS that is running, that's all it means and "Active" is the flag used to point to where boot files are to be created when running a startup repair and "System" is where the system Windows boot files are stored.

The first thing to do is to remove the drive letter of the "System Reserved" partition on Disk #4.

Then power down the machine and disconnect all Hard Disk Drives except the HDD that is currently the Disk 4 (the W_7 HDD) and connect that to the #1 SATA port on the motherboard, then connect the HDD that is Disk #0 (the XP HDD) to the #2 SATA port of the mobo.

Set the HDD that is now connected to the #1 SATA port (W_7) as the second boot device after the CD/DVD drive in the PC BIOS and do the 3 separate startup repairs, with the restarts discussed in this tutorial at the link below to the Windows 7 OS.

That should get you a Windows managed dual boot with entries for both Windows 7 and XP and be sure to post back with any further questions you may have and to keep us informed.

I read somewhere else that my bootloader might point to a wrong disk/directory - I havn't tried to change it, but this it was it looks like according to "easyBCD":

If you had followed BFK's advice, you would only have two HD's showing in Disk management.
