Laptop BitLocker encryption failing
4.5
BitLocker refuses to start encrypting the drive.
Symptoms
- Error message
- Process stuck at 0%
- TPM error
Possible Causes
- Disk errors
- TPM not ready
- Insufficient space
Step-by-Step Fix
1
Run chkdsk /f
Ensure the drive has no file system errors.
2
Check TPM Status
Run tpm.msc and ensure it is "Ready for use".
3
Shrink Partition
BitLocker needs a small amount of unallocated space for its metadata.
When to See a Technician
BitLocker will fail if there are any "bad sectors" on the drive; run a full disk check first.
