I always separate my Main Drive into at least 2 Partitions C-D— and so on —- Windows Programs on C — Data on D —-

Always yes Always have a Image File available —- even if it’s not current you can use it as a starting point instead of starting over—- Lately after I build a machine I’ve been cloning my entire drive and then use the D partition as my Data Backup drive —- several of my machines let you boot from any drive you have installed

It really SUCKS starting over with nothing
