Type "dmesg" to see the last few kernel messages. But that "Terminating selection process. No boot device found" says it all. Your root disk is failing. Make sure you have a good backup.
10.20 is a very old OS and it is not supported anymore. .
F**F = os is running
FA*F = load is 10 or above
F*1F = only one cpu
Boxes with displays like that are pretty old. A 9000/E240 or something like that is my guess. That is not supported anymore either.

NAME
dmesg - print or control the kernel ring buffer
SYNOPSIS
dmesg [options]
dmesg --clear
dmesg --read-clear [options]
dmesg --console-level level
dmesg --console-on
dmesg --console-off
DESCRIPTION
dmesg is used to examine or control the kernel ring buffer.
The default action is to read all messages from kernel ring buffer.
OPTIONS
The --clear, --read-clear, --console-on, --console-off and --console-level options are mutually exclusive.
-C, --clear
Clear the ring buffer.
-c, --read-clear
Clear the ring buffer contents after printing.
-D, --console-off
Disable printing messages to the console.
-d, --show-delta
Display the timestamp and time delta spent between messages. If used together with --notime then only the time delta without the
timestamp is printed.
-E, --console-on
Enable printing messages to the console.
-f, --facility list
Restrict output to defined (comma separated) list of facilities. For example
dmesg --facility=daemon
will print messages from system daemons only. For all supported facilities see dmesg --help output.
-h, --help
Print a help text and exit.
-k, --kernel
Print kernel messages.
-l, --level list
Restrict output to defined (comma separated) list of levels. For example
dmesg --level=err,warn
will print error and warning messages only. For all supported levels see dmesg --help output.
-n, --console-level level
Set the level at which logging of messages is done to the console. The level is a level number or abbreviation of the level name.
For all supported levels see dmesg --help output.
For example, -n 1 or -n alert prevents all messages, except emergency (panic) messages, from appearing on the console. All levels
of messages are still written to /proc/kmsg, so syslogd(8) can still be used to control exactly where kernel messages appear. When
the -n option is used, dmesg will not print or clear the kernel ring buffer.
-r, --raw
Print the raw message buffer, i.e., don't strip the log level prefixes.
-s, --buffer-size size
Use a buffer of size to query the kernel ring buffer. This is 16392 by default. (The default kernel syslog buffer size was 4096 at
first, 8192 since 1.3.54, 16384 since 2.1.113.) If you have set the kernel buffer to be larger than the default then this option
can be used to view the entire buffer.
-T, --ctime
Print human readable timestamps. The timestamp could be inaccurate!
The time source used for the logs is not updated after system SUSPEND/RESUME.
-t, --notime
Don't print kernel's timestampts.
-u, --userspace
Print userspace messages.
-V, --version
Output version information and exit.
-x, --decode
Decode facility and level (priority) number to human readable prefixes.
