Windows 10: Can’t boot windows 7 from an external hard drive

So I have a external 500gb hdd that I want to run windows 7 from, for the nostalgia, I don’t want to use a VM, I want it to run on an actual hardware, now, I know that installing windows to a external hard drive is not possible normally, so I took out the hdd and plugged it to my older laptop and installed windows 7 on it, and when I try put the hdd back in to the sata to usb case and try to boot it up on my newer laptop that is from 2018, it doesn’t boot, gives me a blue screen either the error code 0x0000007B, I thought the laptop was too new and tried on my older laptop that is from 2006-08

  Administrative Tools. .

Also check in BIOS whether External Hard Drive is listed or not.

For help with the BIOS settings, refer to the computer manual or contact the manufacturer.

If it doesn’t work then, I would suggest you to update BIOS for updating BIOS contact Lenovo Support.
