Okay, all of your posts are very helpful and I now have GRUB installed and
can boot up. Now I need to fix the user ID issue so I can use the home
partition and log in. Which I think I can do once I have a shell with root
privileges.
When booting normally, I can't log into my (new) "jim" account, and the guest
account forbids root privilege. Is there another way, such as booting into
troubleshooting some sort of troubleshooting mode?
If I boot from the flash drive, I now know how to use chroot and drive
mounting to "become" root for my installed system. However, can I also mount
/home and have it be placed correctly? Do I need this? I was able to delete
the user "jim" but haven't been able to create the user "jim" without having
/home mounted. I know the user ID and group ID for user "jim" from the old
OS (10000 and 500, respectively).
I tried the command
adduser --uid 10000 --gid 500 --home /home/jim --no-create-home jim
Also, the group ID 500 apparently doesn't exist in the new system. So I need
to create group "jim" with group ID 500 also?
Getting there...but need a little more info.
Thanks again!
