Imagine your computer is a toy box. Every time you want to play, you open the box. Now, what if the lid got stuck?
You couldn’t open it, right? That’s what happens when your computer shows this error. It can’t open the part where
it keeps the Windows system files. This part is called the boot volume.

|---|---|
| Unmountable | Can’t be opened or used |
| Boot | Starting up the computer |
| Volume | A storage space like a hard drive |
So, this error means “The computer can’t open the storage space it needs to start.”
