Ways of restoring OS failures:
- Returning to the “last known good” state (revert boot configuration, but no OS data/applications).
- Reverting to a previous “known state” (revert all configurations and operating system files).
- Reverting to a snapshot (most common in VMs; reverts all data on disk).
Note that Windows writes the “last known good” state during the first login after a boot. “Known state” in Windows refers to “system restore points”.
Interesting idea here: Using PXE boot to pull recovery/live images over the network for forensics/troubleshooting.
