I am using Macrium Reflect 8 on this machine and I had exactly the same issue as this poster here https://www.elevenforum.com/t/pink-boot-menu-after-24h2-upgrade.31230/#post-534720 I did the quick workaround shown here in post 10 https://www.elevenforum.com/t/pink-boot-menu-after-24h2-upgrade.31230/#post-534766 I can confirm this works and size only affects the pre boot screen and desktop is reached normally.
