 **If you're mounting the Windows partition read/write from Linux, Windows should have Fast Startup/hibernation disabled. A hibernated/dirty NTFS filesystem can prevent Linux from mounting it safely; the kernel ntfs3 driver can refuse a dirty volume.**
 
+Run Command Prompt as Administrator:
+```powershell
+powercfg /h off
+```
+
+This disables hibernation and also disables Fast Startup, since Fast Startup uses the hibernation file.
+
+To verify:
+```powershell
+powercfg /a
+```
+You should see hibernation unavailable, and Fast Startup will no longer be available.
+
+To re-enable both later:
+```powershell
+powercfg /h on
+```
