decrypt system drive without rescue image

[DieselDriver]

Hello,

This worked for me:

If you don't have your rescue disk or the previous option is unattractive to you, you can either remove your hard drive and plug it in as an external disk on another working machine, or boot into a live Linux OS on your non-working machine. Once you've done so, install VeraCrypt on the new OS you're working on, then mount the disk as you would a non-system partition. Be sure to go into advanced options when mounting and select to use pre-boot authentication.

Is it possible now to decrypt the system drive without the rescue image?

Thanks, a lot.

Well, yes, it just sounds like you haven't found that option yet, to decrypt that drive from your working operating system. It's there.
