This is a bit of a bump, but I'd like to install Windows 7 Professional on my external HDD, so I can boot from Win7 when need be, instead of being stuck with Win10.
I followed the instructions here, but when I boot to my HDD, it starts showing the windows loading screen, but before finishing, it gets this bluescreen.
I have my HDD split into 2 partitions. One has all my data I need to keep saved. The other is for windows 7. I have the other one as my active partition on the HDD. When I run the program, I select the partition for windows 7 as the one to install to, and the one to create the boot partition on. Then when I restart, I boot to the HDD.
I have tried creating a separate partition on the external HDD just for the boot loader, but it hasn't helped.
Someone said that this wouldn't work when installing SP1, so I've tried installing a version without SP1.
I use 7zip to extract the iso and get all the necessary files.
Also, I have multiple versions of bdcdboot, BootSect, and imagex. I initially used them all from my "...\Program Files\Windows AIK\Tools\amd64". Using the one's from the "...\Tools\ia64" folder causes the application found here to not even work. I don't use the one's from the "...\Tools\x86" folder, as I'm using 64bit.
I changed to using the bootsect.exe from the "boot" folder of the windows iso I'm using.
Someone suggested putting this program and the windows files on the other partition of the HDD I'm installing to, which didn't help. Any ideas?
