Windows 10 & Windows 7 Dual Boot - Can it be done

I tried an 8GB USB drive and I got a message about it not being large enough.

Will try what you have suggested. Thanks.

I forgot a command in there. Between clean and format fs=fat32 quick you need to run create part pri. Just a second, I'll post an example for you.

Running in a Command Prompt (Admin), this is what it looks like:

Code:

Microsoft Windows [Version 10.0.15063]
(c) 2017 Microsoft Corporation. All rights reserved.

C:\Windows\system32>diskpart

Microsoft DiskPart version 10.0.15063.0

Copyright (C) Microsoft Corporation.
On computer: JOHN-LAPTOP

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk 0    Online          447 GB      0 B        *
  Disk 1    Online          931 GB  1024 KB        *
  Disk 2    No Media           0 B      0 B
  Disk 3    Online         7496 MB      0 B

DISKPART> select disk 3

Disk 3 is now the selected disk.

DISKPART> clean

DiskPart succeeded in cleaning the disk.

DISKPART> create part pri

DiskPart succeeded in creating the specified partition.

DISKPART> format fs=fat32 quick

  100 percent completed

DiskPart successfully formatted the volume.

DISKPART> active

DiskPart marked the current partition as active.

DISKPART> assign

DiskPart successfully assigned the drive letter or mount point.

DISKPART> exit

Leaving DiskPart...

C:\Windows\system32>exit

Mount the ISO file:



Copy all the files and folders from the mounted ISO file to the USB flash drive:



Delete \sources\ei.cfg from the USB flash drive.

NavyLCDR, I ended up creating what I believe is a bootable USB but did it a different way than your example.
However, I have ended up with hard disk corruption again. Trying to fix that at present.
Let you know how I get on.

NavyLCDR, Have created two USB Drives using your ammended procedure and both give a problem I have seen before. See first attached image.

From what I understand this message is misleading and what is beieng looked for is a SATA Driver. Using the Motherboard DVD, I have attempted to load a SATA Driver but it fails to load.

When I attempt to boot from the USB Drive, I have to tap F8. This gives me a Boot Menu. See second attachment.

There appears to be two choices. If selected, the first choice (UEFI) simply causes a normal boot into Windows 10.
If the second choice is selected, then I get the 'Missing Driver' problem.

Wow! that was before I was even born... PC's must have been quite cool back then... ?

No PC's then but plenty of Electrical & Electronic kit. Started with an Atari in the 80's I believe; that is 1980's:)
My first PC was in the 90's running Windows 95 Used PCs for my role as a Hardware Support Engineer in Digital Equipment Corporation (DEC) in the late 80's. The first one had a whole 100MB Hard Drive

Hi NavyLCDR
The command dism /get-wiminfo /wimfile:G:\sources\insall.wim has a typo. Insall.wim should be install.wim.

The rest of the procedure went without any issues. Upon reboot I chose Windows 7 it stopped at the Windows 7 splash screen without any error message. Left it there for five minutes and it never went any further. I still think that Windows 7 must be installed first and then Windows 10 added later.

I just tried it on my system. Shrunk my Windows 10 partition by 60GB, created a new 60GB NTFS partition. Applied the Windows 7 Home Premium image to the empty NTFS partition. Ran BCDBOOT. It screwed up my boot priorities in UEFI for some reason, but once I reset boot priorities in UEFI I got the Windows 7/Windows 10 black and white text boot menu. I selected Windows 7 and it went right into the setup routine. A few minutes and 1 reboot later and I was in the screens to create a user account and enter a product key.

Did you apply the image from an ISO file with SP1 included?
