So a workable process would be to:1. Take full backups of all User DBs and the Master, MSDB, and Model DB
2. Completely uninstall SQL Server
3. Re-install
4. Restore all User DBs
5. Restore Master, then model, then MSDB (does the order matter)
6. Restart and pray everything comes back online
Easier might be to backup the user databases (just in case), backup the system databases, uninstall SQL, reinstall SQL. Restore master, that will recreate all the user DBs that the old instance had (providing you left the files exactly where they were), then restore model and masb.
