Therefore, to make things a bit simpler we should know how to make a recovery image to circumvent such scenario. First, we start by creating a folder in any drive except C drive. The best option is creating a separate drive for this whole process. You will only need 3 to 4 gigabyte of storage and that's all.

You can get information about your ESD file using the following command: dism /Get-WimInfo /WimFile:install.esd As you can see, in the install.esd archive there is an image of 4 versions of Windows 10 with the indexes: 1, 2, 3, 4.
