Previously we had to set uefi bios to BCDboot however I was able to upgrade successfully without doint this. Do we know if this is still required?</P> Sat, 19 Oct 2019 23:13:42 GMT https://community.checkpoint.com/t5/Endpoint/Upgrade-windows-from-1709-1903-with-81-30/m-p/65389#M1683 Riverascourtesy 2019-10-19T23:13:42Z https://community.checkpoint.com/t5/Endpoint/Upgrade-windows-from-1709-1903-with-81-30/m-p/65826#M1702 I believe you only need to do this one time.<BR />For future upgrades, this shouldn't be required.
