I installed Catalina 10.15.4 on the nvme Drive on Windows 10 with the help of your EFI
1. First I changed windows installation from MBR to GPT
2. Then created Partition 50GB for Catalina
3. Then increased size of Windows EFI created by default of 100 MB to 200 MB for Catalina
4. Then installed...
know about bios version but while installing Mojave I had to adjust date back to July 2019, so I said. Maybe on only newer models Catalina can be installed.
How to update bios btw z 390 m non gaming.
I manually also checked date in terminal at disk utility but the error showed up, now i am tryig the other EFI
Is it possible that catalina 15.4 having problem with 19,1 smbios ?
UPDATE : it didn't work either. I give up. I better start working on Mojave. Thankyou for your help :)
With this EFI i am able to install Mojave 10.14.6 instead of Catalina Thankyou sir.
Now i have put new ssd then removed every other ssd and then Loaded Optimized Defaults then set BIOS again for install and now I am trying to install Catalina from first EFI
