How to edit contents inside a Virtualbox windows.vdi and make a new vdi from the previous one ?

gistfile1.txt

First of all vdi cant be directly modified in an easy way on Linux
Lets suppose we have all our virtualbox files inside Virtaulbox folder in home directory 
VBoxManage clonehd ~/Virtualbox/windows11/windows11.vdi output.img --format RAW
Above command will make a clone of your current vdi , remeber the output.img will have the fuoll size the windows11.vdi was allocated 
now we have got a clone of windows11.vdi , in form of output.img
sudo losetup -P /dev/loop0 output.img
Above command will mount the output.img as loop device on /dev/loop0
Now , open Dolphin file manager of KDE Plasma , on left sideview it will show an unmounted Partition mount it 
Now you can see the contents of .vdi that was first changed to .img then it was mounted as loop device
Edit replace the files as needed 
Now unmount the partition from dolphin using right click and if you get device busyt error it is because a terminal or some file is opened in the mounted directory
After unmount from dolphin is sucessfull run the command 
sudo losetup -d /dev/loop0
Above command will unmount the output.img from the loo[ device
VBoxManage convertfromraw --format VDI output.img windows11.vdi
This command will make an optimized vdi file from output.img 
After that go in Virtualbox App settings and remove the windows11.vdi and in Filemanger chnage the name of windows11.vdi to windows11.vdi.original.backup
And move the newly created windows11.vdi to Virtualbox appropriate folder and from Virtualbox App reselect the windowds11.vdi as attached hard disk .
Now run the VirtualbMachine the vdi file should work as intended
