I just activated the HP Drive Encryption software pre-installed on the HP ProOne 400 All-in-one desktop after boaut one week of use.
After rebooting, I attempted to log in, but the system did not start. Rather the following message was displayed:
"Unable to unlock media. Please try logging in again after system re-starts."
Same message is displayed when I entered the 3 Spare keys.
Situation remains same after several login attempts.
I confirmed that I entered the correct password and spare keys, because when I entered a wrong password, the message dispalyed is :
"Incorrect password entered. Verify and re-enter. (0xa0)"
or
"Authentication failed. (0x7888)" for wrong pass keys.
Can any one help?
