I was trying to setup Ubuntu 18.04 / Windows 10 dual boot with full disk encryption of the Ubuntu partitions by following this guide:
https://help.ubuntu.com/community/Ma...stemEncryption by Paddy Landau (https://ubuntuforums.org/member.php?u=572807).
I am using a Lenvo Thinkpad with pre-installed win 10.
Everything was like it is described in the guide until the point where I was supposed to restart the system and when I was trying
to boot into Ubuntu I ran into the problem described here: https://ubuntuforums.org/showthread.php?t=2398512, i.e.
when I try to startup ubuntu I get an error 'you need to load the kernel first'. As described there this is apparently expected, because I forgot to disable
Secure Boot as it is mentioned at the very beginning of the instructions.
I then went into my BIOS where I was asked for a password. The problem is to the best of my knowledge I have never setup a password in the BIOS/EFI.
The only thing I can do is press enter, but this only opens BIOS in read-only mode (for example I cannot disable secure boot).
I remember in the Ubuntu installer I was supposed to allow 3rd party installation (Step 2.3 here: https://help.ubuntu.com/community/Ma...sInstallUbuntu) and the installer then asked me to enter a (temporary ?) password for secure boot. I did enter a password there and it included
some non-alphabetic characters (a dot '.' to be precise). I was hoping the BIOS would accept the password I entered there, but first of all it does not let me
type dots at all (it only beeps if I press the dot button) and the password is not accepted either if I leave out the dot. I am a bit lost now and my most urgent
questions are:
- could it be that because I followed the manual installation instructions a BIOS (supervisor) password was set ?
- if yes is it supposed to be the password I entered in the dialog where I was asked to install 3rd party software ?
- what is supposed to happen if this password contains special characters and I cannot enter them in BIOS ?
- is there any other mechanism that could have set the BIOS password (except someone opening BIOS and setting up a
supervisor password) ?
- is it possible to find out when the supervisor was set ? I do not own this computer for long and since I haven't used the
BIOS before this I cannot tell if the password was set when I got the computer already
- any other suggestions what I can do ?
Thanks in advance !
