How to run from VHD Windows XP?

Question

Windows

It failed to start in any way.
XP won't start directly.
The articles write that you need to install 7 on the VHD. But 7 starts, while ignoring its bootloader (installed on VHD). 7 is loaded directly from the main bootloader, but does not use its own.
Running 7 under VHD in the properties of the computer opens the bootloader from an external drive. And when you start the same VHD from VirtualBox, the bootloader uses its own, where XP is also registered and loads XP normally.
Who can give exact instructions on how exactly XP will boot under VHD under real hardware?

Answer 1

No way! It does not support booting from VHD.

And when you start the same VHD from VirtualBox, the bootloader uses its own, where XP is also registered and loads XP normally.

It is the Box that launches, not the HePe itself.
