This may help, different OS's but the same methods can be used: https://support.microsoft.com/en-ca...ou-use-windows-vista,-windows-7?wa=wsignin1.0On dual boot Windows 10 and Windows 7 on separate drives the Windows 10 kills System Restore Points upon restart
Thank you for your help.
Yes, of course I have. When booting into Windows 7 its Restore Points are intact. On the contrary, booting into Windows 10 the Restore Points have been vanished.Have you checked each OS settings that there is sufficient space allocated for them to be created in the first place?
Thanks all the same.Then I have no idea, sorry. Maybe someone else will add their input here.
Following my previous post I quote as attachment the view of Boot Sector of my Windows 10 just in case someone can diagnose something having to do with my problem.Thanks all the same.
