Hi Everyone,

Info:
1. I am new to virtual box
3. The system consists of dual boot (Windows + Ubuntu)
4. Virtual Box is installed on Ubuntu
5. The location of the snapshot is on the NTFS drive which is D: of the windows system.
6. The snapshot was damaged after rebooting with Windows OS and then back to Ubuntu
7. The latest/current Snapshot size is changed to 0 bytes
8. There are multiple snapshots that are taken previously and seem intact Issues:
1. The current image doesn't have preheader info. In fact, it doesn't have anything at all.
2. When trying to restore the old snapshot it says the current snapshot doesn't have header info and cannot restore it. Solutions I tried:
1. Replace the first 72 bytes of the corrupted snapshot with the other snapshot. It didn't work.

Question:
How to delete the current snapshot and restore the previous snapshot?

Let me know if error logs are needed.

Mpack is the present forum virtual disk guru, he'd quite likely know about preheaders and such.

The question I have is, do you ever intend to go back to any of these previous snapshots? If not, you would do a lot better to clone the snapshot chain to a new single drive file, using Mpack's CloneVDI and the instructions therewith.
