Running Windows 7 from an external HDD?

Question

Windows

The essence of the problem is this. Once upon a time there was a Seven on my home PC, it worked without problems, but then I had to rearrange the hard and eventually save all the data on it. More than six months have passed, my native PC is thousands of kilometers from the screw, and I tried to start Windows from it, installing it in a portable case and turning it into an external USB-HDD. So, if I insert the disk directly into the laptop, then the system boots only in compatibility mode (not AHSPI), otherwise the bsod crashes. In the case of loading from an external box, the system crashes in any case and indicates an error 0x000007b.
How do I restore it to portable run on my laptop?
UPD: After a long and hard tapping on the tambourine and dancing until the neighbors arrived from the bottom, the seven still wound up from my screw, in the usb box.
I did this with the help of a batch file and a standard similar OS, which is installed on the internal hard drive.
Here I will post a detailed manual + video (possibly): link (not advertising)

Answer 1

The problem is that the drivers in Win7 on the hard drive are installed for the old PC, but they are not for the laptop.
