Exception: no disk founded

[Toktatop]

i have geted answer: (You cant use the VFS on real hardware since its a virtual filesystem) but what can be used besides VFS

why when I run my OS on a real computer via flash drive I get an error: (Exception: disk not found)
here my code:
`using System;
using System.Collections.Generic;
using System.Linq.Expressions;
using System.Text;
using Sys = Cosmos.System;

namespace test.os

string crd = @"0:";
protected override void BeforeRun()
{
fs = new Sys.FileSystem.CosmosVFS();
Sys.FileSystem.VFS.VFSManager.RegisterVFS(fs);
clear();
Console.WriteLine("type 'help' for help");
}

    protected override void Run()
    {
        Console.Write(">> ");
        var input = Console.ReadLine();

        // charge place
        if (input == "shutdown")

You cant use the VFS on real hardware since its a virtual filesystem

[9xbt]

Well you can but it requires very specific specs which are really rare

[9xbt]

Not really a Cosmos issue but its your hardware that doesnt support the VFS

[Toktatop]

what can be used besides VFS

[GoldenretriverYT]

no, this is plain wrong. A VFS is an abstraction layer and does not require some "specific" hardware to be emulated. The only problem is that the Cosmos VFS and the disk drivers are just not that good.

There is no SATA & NVMe Driver, so you are gonna have to connect your drive using IDE. Also, you need to properly format your drive to be recognizable by Cosmos.

[9xbt]

Well if it doesn't support SATA or NVMe then you cant use SATA or NVMe so you need a computer that has IDE, that's what i was trying to say

[9xbt]

I didn't really want to complicate this but whatever
