Well, if you can get to SET/STARTUP then you might consider this:
- Boot into conversational boot
- SET STARTUP_P1 "MIN"
- SET UAFALTERNATE 1
- CONTINUE
This procedure only works if there is no alternate SYSUAF file present
on the system disk.
Next, logon with SYSTEM and VMS will ask twice for a password. Just
enter the same password twice (and keep it simple :-)
= SET DEF SYS$SYSTEM
= DEF/USE SYSUAF SYS$SYSTEM:SYSUAF.DAT
MC AUTHORIZE MOD SYSTEM/password=   eetc.

This works a little better if you know that SYSUAF.DAT is in SYS$SYSTEM

 Conversational boot to get the SYSBOOT> prompt
 SYSBOOT> SET/STARTUP OPA0:
 SYSBOOT> CONT
 $ SET NOON
 $ SPAWN
 $ @SYS$STARTUP:VMS$INITIAL_050_VMS.COM
 $ SET DEFAULT SYS$SYSTEM
 $ MCR AUTHORIZE
 UAF> MODIFY SYSTEM/PASS=mumble
 UAF> EXIT
 $ MCR SYSGEN
 SYSGEN> USE CURRENT
 SYSGEN> SET/STARTUP SYS$SYSTEM:STARTUP.COM
 SYSGEN> WRITE CURRENT
 SYSGEN> EXIT
 $ @SYS$SYSTEM:STARTUP.COM   ! System should now boot normally and you can 
login
