MP 1,1-5,1 Installing Windows 10 in Legacy/BIOS mode in cMP with Boot Camp Assistant

Try again

I tried several times. Still nothing. It finishes in less than a minute.

The image may not be original and does not match the path - /V*/*/sources/install.*
Although there would be formatting, but your formatting is also missing.

Perhaps the mkntfs utility was unable to format the 1TB partition

The same image works fine for hybrid MBR. Also tried the Windows 7 image with the same result. That one also works fine for hybrid MBR.

Could not open /dev/disk12s1: Resource busy
Windows Install disk12s1 Applying image 4 ("Windows 7 ULTIMATE") from "/Volumes/GSP1RMCULXFRER_EN_DVD/sources/install.wim" to NTFS volume "/dev/disk12s1"
Volume BOOTCAMPMBR on disk12s1 mounted
hivexsh: failed to open hive file: /Volumes/BOOTCAMPMBR/Windows/System32/config/SYSTEM: m

It is failing to apply the image to the MBR partition.

I noticed that even if I mount the image and drag/drop the Install.wim it immediately unmounts the iso and the Wim file of course disappears.

Maybe try dividing the disk into 2 or 3 partitions

Thank you, I will fix this.

This is how the mkntfs utility formats

Yes I had to disable spotlight again, but still it creates an empty drive.

Try changing the name. The mkntfs utility worked, but now Wimlib does not want to work.

Doesn't help. The drive is seen as an external USB disk and I see a lot of unmounts/remounts.

Again formatting did not happen. I'm sure it's a disk problem. Above in my attachment you can see that the installation was successful.

It looks like there is a problem with the external drives. I mounted the SSD as an internal drive below the DVD-ROM and it worked fine.

I install Windows using a program only on an external USB drive, and the first launch of the system with a hybrid partition, or MBR, I do on a SATA connection on my daughter's computer.

I noticed that even if I mount the image and drag/drop the Install.wim it immediately unmounts the iso and the Wim file of course disappears.

Fixed. Updated the program.

I found a very old HDD disk and three times in a row what happened to you happened, on the fourth time the installation started. I don't think there will be such problems with SATA.

7th time in a row. No go. Watch the external drive icons on the right.

Old Toshiba HDD, there is no such problem with SSD. It may also depend on the SATA-USB adapter.
Added pauses - try it.

Yes I saw that. But why? There is no lock there?

Off topic, but when I install Windows onto an external drive using a VM and whole disk mode I notice I have to explicitly unmount the disk for any disk manipulation on the drive as it will try to be remounted (even if it does not reappear on the desktop). This may only apply to VirtualBox, but I wonder if something similar could be happening here?

 

[startergo]

So, if you explicitly unmount, but it keeps remounting there is no cure. How did you go around that? Or are you saying that it unmounts/remounts automatically?

 

[startergo]

@tomsmods @Sergey-Galan
I have attached the external drive to my MacBookPro15,1 running Sonoma.
Disabled indexing sudo mdutil -i off /
Unmounted manually the partition and Installed Window 7 in MBR mode.
Enabled indexing sudo mdutil -i on /

Unfortunately the above procedure does not work for Windows 10 ISO. Go figure.
I can install Windows 10 in UEFI mode, but not in MBR nor in Hybrid on the external disk.

 

[startergo]

So, you have to disable automount to install Windows 10 on an external disk in MBR or Hybrid modes.
Tested. Working.
