If you just want to reset the password on the new imaged BBB (this does not explain why you had issue in the first place, but does allow you to access the system) clear the encrypted password as follows, (if you need detailed steps let me know) create a sdcard with a new image (one you download) and boot the BBB with it. then mount the emmc device edit /etc/shadow file in the mounted emmc device (requires sudo) find the user name you want to remove the password on for example, my user name is 'amf' amf:$6$jlBY96dq$V7tFs2xEv.a3kXArkyTEcEbGDX43d6UpzMcy/aplV8khxUFJKPMg0ugGBfWVZMpJRpaMXAATEAb5inu7/G.Iz1:16406:0:99999:7:::
delete the stuff between the first two '::' pi::16406:0:99999:7::: save the shadow file power off the BBB remove sdcard, and power on the BBB log in with the user name that the encrypted password was deleted on, no login password is required, then set new password for the user. Hope this helps. amf On Tuesday, March 30, 2021 at 9:02:25 AM UTC-5 propg...@gmail.com wrote: > I am now attempting to get into GRUB during boot.
