HOW TO INSTALL DUAL BOOT 10/7 SYSTEM ON NVMe DRIVE WITH 10 FIRST?

topgundcp said:

Setting 10 to be default will not do the job, it only shows which Windows is displayed on Boot Menu first, but rather depending on which Windows you run the "bcdboot" command from.
While running Windows 10, assuming the drive letter of Windows 7 is assigned to D: then from Admin command, you'd run:
bcdboot D:\Windows
In this case, the BCD is created in Windows 7 hence you'll get the ugly non graphical dual boot menu.

To get the Blue graphical dual boot menu. You must boot into Windows 7. Assuming while in Windows 7, Windows 10 is assigned to letter X:
then run: bcdboot X:\Windows which will create the BCD in Windows 10.

hello top...i tried your suggestion but heres what happened

i was wrong by stating: "you must boot into windows 7". Actually, it does not matter which windows you boot from. To get the graphical dual boot menu:

1. while in windows 7, use: bcdboot x:\windows where x is the drive letter of windows 10. But for some reason, you get an error.
2. while in windows 10, use: bcdboot c:\windows

either 1 or 2 should give the same result.

thank you :)

That might indicate there is corruption of the image.

You could check by using dism++ to apply the image to the partition ( it is on the menu ).
[If the target partition has got gecrappen on it - format it first with bootice or diskpart]

Then you need to add a boot menu entry - nt6repair is also on the menu.

Put a tick in the box for efi.
You can click ??? to check you have selected the correct windows partition before clicking Apply.

hello again SIW2 i tried the dism but it wouldnt let me apply the image to D; root...rather i had to create a directory to extract into which created other problems so i wiped the mess clean again to try to install from the flash drive....but here are the errors i got... AGAIN it said i cant install into a GPT partition even tho my bios is set to UEFI

i tried the dism but it wouldnt let me apply the image

I presume you mean dism++ ( which is not the same as dism)

What do you mean by

it wouldnt let me

?

Did it give a message?

it said i cant install into a GPT partition even tho my bios is set to UEFI

You need to boot the usb stick in efi mode.

Press F12 for the one time boot menu and there should be two entries for the usb stick.

it said i couldnt install into the D: root directory rather into a sub folder which gave me an undesired result especially when i wanted to move everything into the root...

i tried again the run the installer from inside win10...i encountered no disk partition errors this this but when it got to 18 % of the files being expanded, i got this error again

It might be useful if you fill in your system specs.

when you run dism++ in the booted media , what does it say at the top left of the main window?



What you have posted seems to indicate 2 different issues:

1. the media is not booting in efi

2. the image is corrupted.

i tried the dism but it wouldnt let me apply the image

Possibly because the media is not booted in efi mode

it said i couldnt install into the D: root directory rather into a sub folder which gave me an undesired result especially when i wanted to move everything into the root...

Extracting the image with dism++ to see if it completes the extraction.

If it gives an extraction error, that would confirm a corrupt image.

OK...heres what i did...

heres my present drive set up as shown in my disk manager


so i performed a dism command thru an admin command prompt from the desktop...everything went fine in about 45 seconds it was finished...afterwards i checked the properties of the windows directories as it was written to the SSD
& it was about 17.7 GB of goodies.

i even configured the boot menu as i wanted to be in the win 10 style with 10 as the default & 7 as the optional...

my problem now is when i choose to boot into win 7 i see the 4 swirling colors just fine...but then it stops booting, win 7 doesnt finish loading & the computer restarts into the recovery options mode
is there an option inside the program you wrote that would repair or fix this to allow win7 to be properly loaded?
i saw the nt6 repair windows you posted but i dont know how to use that utility & i dont know what all the settings mean...im willing to learn but as of now ii hesitate to create more problems

As your M.2 MVMe drive is already UEFI - GPT, you MUST install Win 7 64 as UEFI. Don't change the BIOS, leave it as UEFI.
ON BIOS just check if Secure boot is disabled.

hello this is the bios i have...i dunno if i have any option to boot usb in efi mode IM TRYING TO ATTACH A SCREENSHOT but the file attachment manager isnt working...its retaining files from a year ago without deleting them & wont let me upload any new ones...has anyone checked this to fix it?

Been a long time since 2009 I last used Acronis. However, I believe it should allow to clone partition like any other backup software. Most people use : Macrium Reflect free for this.

But.... Here's what I would do to install Windows 7 on the partition that you've already reserved on the SSD.

1. From Windows 10, copy the install.wim under sources folder of the Windows 7 disk to Windows 10 desktop
2. Open Admin command prompt then navigate to desktop: cd %USERPROFILE%\desktop
3. Type: dism /Apply-Image /ImageFile:install.wim /Index:1 /ApplyDir:X:\
   NOTE: replace X with the drive letter of the partition you intend to install Windows 7
4. then type: bcdboot X:\Windows
5. Reboot the PC, you should have a menu for dual boot, select Windows 7

Hi, i registered just to thank this man.
I was struggling with a Windows 7 installation on an Industrial Notebook which was uncompatible with 7 and also has NVMe.
Following this method worked as charm, we have a dual boot now.

Thanks.
