How to run OS from physical partition on current drive in VirtualBox?

Question

linux

We have: a laptop with an SSD, on which two operating systems are installed: Windows 10 and ArchLinux. And between them is a common section with files. GPT markup. Used by UEFI for booting. Everything works well, but I came across an article ( mnorin.com/ispol-zovanie-fizicheskogo-diska-v-virt... ) and a "Wishlist" appeared: boot an existing OS under another, for example, Linux under Windows using VirtualBox.
In general, if anyone has come across, advise how to do it right. Thanks in advance!
Why the article does not solve my question: if you connect stupidly according to the article, then there is no partition table. Because of what we do not boot, and the EFI loader needs to be connected somehow.

Answer 1

You also need to connect the partition with ESP to the guest, having previously disconnected it from the host.
