Windows 7: Want to make Win 7 System Partition DualBoot

Still cannot do. Get a message that "this drive is on the same physical disk as your system drive."

Was looking at Bootrec , but none seemed exactly right. Maybe you know better or have thought of something. I fell asleep in the middle of typing this and think I'd better quit for now.

Night Hawk, you are so quick, you posted while I was asleep.

Nothing in the BIOS, in fact it is very, very simple. Can enable virtualization is about it.

This is a second internal hard drive, not an external drive. So good of you to think of all the contengencies, but it doesn't even travel much around my living room. Mostly sits by my recliner while I use fabulous Firefly corded keyboard which shows a light through the character of each key so I can easily type this at night. It can't wake the computer either.

Hope answers helped, migraine is coming on rapidly. Good night for now.

Oops, forgot: Win 7 was booting fine all by itself with the C Vista drive removed after I did the repair install.

Your present boot loader and mbr entries are on the internal C Vista drive there. In order to see the external drive made bootable on it's own you may have to perform an upgrade repair install with the internal unplugged. Once made bootable as a stand alone drive you can install EasyBCD on both Vista and 7 while keeping one as default preferrably Vista being on the internal drive.

Being too late and falling asleep is nothing to rush into here! Get that first and then take a fresh look at things so far on the thread here. That will be the best option for you since that can help in avoiding mistakes along the way.

But, these are two internal hard drives, and I have already taken out the Visa hard drive and done the repair install on the Windows 7 installation as a stand alone. And it booted all by itself just fine. I do have EasyBCD on each.

With the Vista drive added back in with the 7 drive set as default you can now add Vista into the new 7 bcd there for a dual boot while still seeing the 7 drive as a stand alone. The EasyBCD entry will simply point to the Vista boot loader on the other drive.

One thing to note is the drive association option seen in EassyBCD itself. When swapping drives around and drive letters subsequently are changed you can go in and reassign the new drive letter for any OS added into the bcd store in the advanced Settings.

Note the screen presently showing C for the 7 install here. You can see how if a second OS like Vista for example may be on F, G, H, etc where you would simply select the correct drive letter for that installation as set in the 7 Disk Management tool and click the "Save Settings" button to see that set.

(latest build 100 beta in use here)

The WIndows 7 drive is still not marked System, so the Win7 imaging app will always want to include Vista in the image since it still contains the System MBR.

The solutions to this are to:

1)Follow my initial suggestion which is to adopt a BIOS-managed Dual boot, where both HD's/OS's have their own MBR, EasyBCD entries are removed (using Add/Remove tab) and the booting is done via the BIOS boot order and BIOS Boot Menu shortcut key.

You would set Win7 HD to boot first in BIOS setup, recover the MBR into it while Vista HD is unplugged, then when you plug Vista HD back in it would be booted by tapping the key given on first boot screen for one-time Boot Menu, which is ESC for HP's.

2) You can continue with a Windows-managed Dual Boot, but the MBR must be on the Win7 HD, not the Vista one. To achieve this, you mark Vista Inactive using DISKPART or free Partition Wizard bootable CD, make sure Win7 is marked Active and first to boot in BIOS boot order (after DVD), then boot Win7 DVD Repair console, click thru to Recovery Tools list to run Startup Repair up to 3 separate times with reboots until it starts up, then add Vista using EasyBCD 2.0 on Add/Remove tab - you may need to remove it first to add it correctly.

Once again, you currently have the MBR on Vista. To image only Win7 with Win7 imaging, you must either move the MBR to Win7 using Step 2 above, or adopt a BIOS-managed Dual Boot where both HD's have MBR's and are booted via BIOS boot order or ESC Boot Menu key, with no Dual Boot menu given.

If you decide which you want to do, feel free to ask any further questions or for more detailed steps.

I've unplugged and replugged the Vista drive back in when running the betas and RCs without ever needing to mark any partitions. EasyBCD was actually installed on both while both drives had seen stand alone installations already from the existing XP/Vista dual boot at the time.

All you needed to do was set the 7 drive as default in the bios once again after replugging the Vista drive then seen as HD0 back in and add a new entry into the then 7 bcd store. If I were to install Vista now on this case on another drive while the 7 was still plugged in Vista would become D as seen by 7.

Once the 7 host drive was unplugged and Vista saw a repair or full install to make that other drive a stand alone and the 7 host was plugged back in Vista would still load when selected. When EasyBCD was installed on Vista and 7 was added in there then seeing the Vista drive set as default 7 would still load as well when selected. Despite both being separate editions they share the same boot loader.

That is the problem: both share the same bootloader and it is on Vista.

It needs to be moved to Win7 to stop the imaging app from wanting to include Vista in Win7 image. The imaging app wants the MBR included and it is on Vista.

Or: To make both independent, stand-alone drives booted via BIOS means recovering the MBR back into both (while the other is unplugged) until both are marked System and boot via BIOS. Any EasyBCD listings need to be removed or Windows Dual Boot manager will intrude.

When adding Vista into the 7 bcd while having each on separate drives both were stand alone OS where the loading of Vista when selected would then see the choice at the time to boot into XP or Vista having been the previous dual boot seen in the Vista bcd. The 7 RC was also added into the Vista bcd as another option while each drive remained indepently bootable if run by themselves.

Once the 7 drive is made bootable as a stand alone there the addition of the Vista entry is basic once plugged back keeping the 7 drive set as the default. The second trip into the bios however will be needed since the Vista will still be HD0 and automatically be set as the first default drive once replugged unless data cables are reversed for seeing the 7 drive plugged into port #1 on the board.

The image taken of any drive is strictly what is on the drive itself. For a backup of the 7 drive the added entry for Vista would be preserved while nothing on the Vista drive is included in the drive image unless the drive is also checked off to be included.

I have read this last night and tonight and am still confused. However, that is probably due to the distractions going on in my life now. Just letting you two know I am paying attention, not ignoring you.

Maybe if you explained what I did wrong when I removed the drive and did the repair install of Win 7. I would have thought that would have put a stand alone MBR and bootloader (is this correct terms, anyhow whatever was needed) on the Win 7 drive then.

With the repair install the 7 should be booting up normally as you would expect it to. When going to add the Vista drive back in especially if that was plugged into the first sata port on the board it will then become the default boot drive in the bios.

To insure the 7 drive is the first default drive and later add an entry in for Vista you can opt to switch the data cables between the drives seeing the 7 drive then plugged into port #1 which makes any further repairs easy being the first drive or simply go into the bios, integrated peripherals, hard drives clicking enter to bring up the list of hard drives installed and move that to the top of the list. Then simply exit and save the new bios setting made.

Once booting by default into 7 you can add the new entry for Vista into 7's own bcd store on that drive using the EasyBCD tool. You will need to sign up at the neosmart forums however to download the latest beta build 100 now seen until the new 2.0 version is final and made public. The old 1.72 was written for Vista and would see the Vista boot screen replace the newer animated 7 boot logo if that is used.

Once the Vista entry is added and you can even name that what you want to be showin in the boot options screen you simply select it to see Vista load rather then 7. You can leave 7 as the default OS or change it to Vista. The amount of time for the boot options screen to be display can be reduced from 30 down even under 5 seconds to speed things up as well.
