Default Dual Boot Windows 10 and Hackintosh on Same SSD Drive

I installed Catalina 10.15.4 on the nvme Drive of Windows 10 Installation:

1. First I changed windows installation from MBR to GPT
2. Then created Partition 50GB or whatever you desire for Catalina
3. Then increased size of Windows EFI created by default of 100 MB to 200 MB for Catalina
4. Then installed Catalina
5. Then Renamed bootmgfw.efi to bootmgfw-orig.efi in EFI/Microsoft/Boot/ so the windows option will showup in clover to boot from Windows EFI
thats it.

Now to change your Windows 10 installation from MBR to GPT use the commands below:

mbr2gpt /validate /allowFullOS
and then
mbr2gpt /convert /allowFullOS

Now to Increase the size of EFI from 100 to 200 MB
I used the information on this page:


Then to make hackintosh and Windows bootable use this information here:

that's all!!!

Now you have Windows 10 and Hackintosh on the same NVME drive
