1. An information handling system, comprising:

  • a processor;

    a memory communicatively coupled to the processor;

    a storage resource communicatively coupled to the processor; and

    instructions stored in the memory, the instructions, when loaded and executed by the processor, cause the processor to;

    determine an encryption status of a boot volume of the storage resource;

    initiate encryption or decryption of data stored on the boot volume;

    track the encryption status of the boot volume by periodically storing, during an encryption or decryption of data stored on the boot volume, a variable indicating a portion of the boot volume that has been encrypted or decrypted and whether the boot volume is partially encrypted or decrypted;

    in response to an interruption to the encryption or decryption of data stored on the boot volume, determine whether the boot volume is in a partially encrypted or decrypted state; and

    based on the determination that the boot volume is in the partially encrypted or decrypted state, boot from the boot volume in the partially encrypted or decrypted state.
