Don't install software in a root folder, or from a root folder.

Also, right click and use "Run as administrator" when running the VirtualBox installer.

If your English is not good then don't use English to post. Use whatever language best suits you. We'll use an online translation service to understand it, assuming we don't already. See DeepL Translator.

Throwing in too, that if you installed Virtualbox in the D drive, this will not force your guests onto the D drive. Virtualbox is only 250-ish MB and should go in the default C:\Program Files\Oracle\Virtualbox. You can set new guests to go to a folder in the D drive using the main Virtualbox window's File menu, Preferences, General tab, Default Machine Folder.

Your guest does not have a CD drive in it, so there's no way to install an OS. The drive is 16 terabytes?! Eek. Did you get this guest as an importable OVA appliance?

Try a fresh new guest. Read the manual, section 1. It explains how to set up a Virtualbox guest.

I didn't notice the 16TB thing. No way XP is going to install on a 16TB drive. I don't see how XP can use that drive at all. So, either the YouTube tutorial guy is a complete idiot, or the OP is not doing what the tutorial said. But, I don't intend to parse an outside VLog anyway.

But that is not the immediate error, the immediate error is unchanged from the first post: for some reason it's referencing a root folder, which modern Windows will not like at all. I assume the OP tried to install VirtualBox in the root of drive D.

In your first post you mentioned that your English is not good. That's fine. Use a translating website, like DeepL or Google Translate.

The 'leading double slashes' error means you installed Virtualbox on the root of the host PC's drive instead of the default 'C:\Program Files\Oracle\Virtualbox'. Installing Virtualbox on a different drive does not cause the guest files to be on that drive. The guests will still go on 'C:Users\{you}\Virtualbox VMs'.

You should uninstall Virtualbox and ignore/delete that tutorial you have been watching, it is all wrong.

Reinstall Virtualbox by right-clicking the installer and choosing Run As Administrator even if you already are an administrator. The installer might remember that you installed on the D drive root. If so, manually point the installer's folder location to 'C:\Program Files\Oracle\Virtualbox'. When Virtualbox opens, install the Extension Pack if you want. Close and re-open Virtualbox.

In the main Virtualbox window, File menu, Preferences, General tab, Default Machine Folder, set this folder location to a folder on the D drive. Now all new guests will go in the D drive.

Install the XP guest according to the instructions in section 1 of the manual.
