sebus Posted December 31, 2021 Share Posted December 31, 2021 (edited) OC 0.7.7 Dell Optiplex 3046, Windows installed on internal SSD SATA drive (own EFI default Windows bootloader), Big Sur installed on SATA SSD (own EFI with OC) connected to Marvel based PCIe SATA controller Dell BIOS has to have "Enable Legacy options ROM" for this controller to be bootable No matter what I set in ScanPolicy, I cannot remove Windows only ( I have tried just about every combination) Ofcourse I can boot to Windows directly with F12 (or set it as a default boot option) https://oc-scanpolicy.vercel.app/ If I uncheck ONLY OC_SCAN_ALLOW_FS_NTFS , I get this instead! (which makes NO sense) The only way I can get Big Sur boot option displayed, is to use ScanPolicy=0 Anybody has any ideas?

Avery B Posted December 31, 2021 Share Posted December 31, 2021 The windows EFI is still on a FAT/FAT32 partition, so you'd want to disable ESP file systems I think. 1 Link to comment https://www.insanelymac.com/forum/topic/350207-solved-cannot-remove-windows-from-picker/#findComment-2774419 Share on other sites More sharing options...
sebus Posted December 31, 2021 Author Share Posted December 31, 2021 Ofcourse I have tried each & EVERY combination inc with ESP disabled I get no OS choice at all I do understand how it is supposed to work... but it does not sebus Link to comment https://www.insanelymac.com/forum/topic/350207-solved-cannot-remove-windows-from-picker/#findComment-2774420 Share on other sites More sharing options...
Guest 5T33Z0 Posted January 1, 2022 Share Posted January 1, 2022 @sebus Works for me, even with the ESP Bit disabled. Which drivers do you have enabled?

sebus Posted January 1, 2022 Author Share Posted January 1, 2022 (edited) In the end I was advised to use 257, which indeed hides Windows entry only! (exactly what I needed) sebus edit It is hardware independent, moved this drive to another setup with Asus WS C246M Pro, corrected OC config and the same 257 ScanPolicy is the only option that works as expected Edited June 2, 2022 by sebus Link to comment https://www.insanelymac.com/forum/topic/350207-solved-cannot-remove-windows-from-picker/#findComment-2774433 Share on other sites More sharing options...
