Hi I am running Catalina on my Dell Latitude 3400. Now I would like to dual boot to windows 10. Is it possible ?

The systems does not give me an option to choose the installer, it reboots to Catalina. How do i fix the NVRAM, so that my system reboots to the installer ?

Thanks

Hi I have installed Catalina on my Latitude 3400. I've used open core. Now I want to update to BigSur. When I try to update using the system software update, I am caughted in a loop. The system downloads BigSur, and starts the installation. When it says it's going to restart it gets back to Catalina.

@Jake Lo it is a Qualcomm QCA9377/QCA61x4A wi-fi adapter @tanya My Dell 3400 uses the Qualcomm QCA9377/QCA61x4A wi-fi adapter. What about yours ?

Hi @tanya I've used your Davidfrei7as EFI with airport and nothing. No wi-fi.

@Tanya , are you using internal Latitude 3400 wi-fi card or an external one ? Is your airdrop working ? [email protected]

@Tanya i have used with success, the EFI from @davidfrei7as. My 3400 trackpad is working fine under Catalina

Hackintosh my Dell Latitude 3400 I quit BigSur and decided to start from zero with Catalina. I am running BigSur on my mini MAC. Can you please help on this task ?

As you can see the partition map is GUID and the format is Expanded(with journaling), so it must be another problem. now I get this error message the system keeps rebooting in cycle, showing this screen

i select 2 and get : " OCB : load image failed - access denied "

Installation done It did reboot to this screen : As I don't want to fail, please tell me what to do next.

ok Now I got it right it's installing. Thanks

actual disk status before reformatting this is ok ? no option to select GUID

after choosing 3 i get : " OCB : load image failed - access denied "

This is my boot menu from the USB installer disk. Which one is my internal disk ?

no I did not how do I do it? I did do it, only to the USB installation disk

@Hervé @tanya @Jake Lo i have tried you suggestion , using F12, but nothing changes Now when I boot , this is what I get

@tanya please help after the installation of BigSur, the systems reboots but does not boot into Mac OS. i remove the usb disk and this is what I got after rebooting this are my boot settings

@Hervé @Jake Lo @tanya Tanya, can you send me a print screen of your bios boot options ? When I choose to boot with open core it boots directly into the bios

@Jake Lo @tanya @Hervé I finally installed Big Sur. I have removed the USB disk. Now when system reboots it goes to BIOS. What do I need to do now ? Add a boot option in the Bios ?

@tanya As today, what is not working, on your BigSur Latitude 3400 ?

@Jake Lo In which system file , do I have to format my SSD drive to install BigSur from the USB disk ?

I've created the USB Disk. Now, on my Dell Latitude 3440, I can't boot from the USB DISK. It Boots from windows even with the BIOS changes. When I get out of the Mac OS, I have to unmount and eject the USB Disk , right ? Success booting from USB Disk. When selecting disk to install BigSur, I choose the notebook intern SSD disk, and it tells me " This disk is locked". Can't go any further

I have just created a Mac OS Big Sur bootable USB Now I'm trying to mount the EFI partition of my USB disk, but it does not appear on the OpenCore Configurator window. Disk list from terminal
