Windows 11 Dual Boot Possible?

Hello, I'm new to the forum and Zorin , but have been a Linux user for 10 + years dual booting with Windows since the beginning. I recently built a system with two drives and have Zorin and Windows 10 on different drives both using TPM 2.0, UEFI, and Secure Boot.

I verified with system info in Win 10 on Linux drive with the command line.
~$ mokutil --sb-state
SecureBoot enabled

~$ ls /sys/firmware/efi
config_table  esrt              fw_vendor      runtime      systab
efivars       fw_platform_size  mok-variables  runtime-map  vars

~$ dmesg | grep -i tpm
[    0.000000] efi: ACPI 2.0=0x9eb4f000 ACPI=0x9eb4f000 TPMFinalLog=0x9ebb9000 SMBIOS=0x9f539000 MEMATTR=0x996f2018 ESRT=0x9b535818 MOKvar=0x9a6a8000 RNG=0x9f551e18 TPMEventLog=0x93a89018

Right now the prospect of dual booting the final release of Win 11 is looking pretty good based on the known hardware and security requirements and I will have an answer to my question soon enough. For anyone following a similar path do some research on secure boot . UEFI, and MOK as it relates to Debian/Ubuntu based distros.

You need to disable secure boot to install Zorin OS. If not there is a high chance you cannot install.

You don't have to, Zorin Os actually supports Secure Boot and UEFI, it is recommended that you disable it if you're having problems.

Point me out if I'm wrong :grin:

@Kedric , you are correct . Secure boot causes problems for some users, but will be a requirement for Win 11. AFIK most Ubuntu/Debian based distos support secure boot.

If your system has a supported processor, you should have no trouble upgrading to Windows 11.

You can check your system from Windows 10 with whynotwin11 or wait a few days until Microsoft releases the updated version of PC Health Check (it is currently available to Windows Insiders but release to the public is imminent), and use that to check your system. Since you are running Windows 10, you will (soon, I hope) be able to use Windows Update to check compatibility.

As others have pointed out, Zorin works with Secure Boot, so if you are having no problems now with Secure Boot enabled, you should not have any problems with Secure Boot after upgrading to Windows 11.

Not necessary so.
I have installed both Win 10 and 11 on a Gigabyte m/b with secureboot disabled.

It is true that you can work in zorin with secure boot enabled. During the first configuration and updates to the kernel/drivers, it is recommended you disable secure boot so it doesn't cause issues. Most Linux drivers are not signed and until installed/updated, it may cause failures if enabled.

Be aware that if you perform a bios update this will most likely reenable secure boot.

The requirement is "UEFI, Secure Boot capable", that is, UEFI enabled, Secure Boot capable but not necessarily enabled.

Yeah, well ... this is a failure on the part of OEM's and community driver developers.

OEM drivers are almost always signed. The issue arises when (and for the most part, only when) an OEM doesn't bother to make a Linux driver, forcing the task of reverse engineering to develop drivers onto community members.

My response has been to refuse to use any peripherals for which the OEM neglects to make a Linux driver. As @FrenchPress pointed out in another thread, such OEM's are not reputable. Why support OEM's who don't support Linux?

I understand your perception, but all of Linux is based on community contributions anymore. To say that because a developer is not part of an oem company they are not reputable is to say Linux isn't reputable. It then begs the question, why are you using it? Just saying.

I didn't say that community developers are not reputable. Quite the opposite.

This is the exchange that I was referencing:

Tom: "The major OEM's (e.g. Intel) keep kernel drivers up to date for the most part. Many others don't."

FrenchPress: "Good reason to stick to a reputable brands :slight_smile:"

I misunderstood, my apologies.

No problem. I'm often not as clear as I should be.

I also tend to skim through posts, not reading as i should, making my understanding flawed.


Found something that might help you:

It wasn't lack of support but an Ubuntu update that broke this. Follow the recommendations in the above thread to resolve your issue.

The system was built around a supported CPU. PC health check was giving mixed results with no explanation as to why some systems were not supported and pulled by MS. I'm waiting for the final release of Win 11 before proceeding due to possible changes and also, I don't want to be part the Windows insider program.

I had to use MOK for enrollment of a Nvidia driver, the rest were included with the kernel.

You should be good to go then when Windows 11 releases on October 5. Although it might not happen as quick as you would like, Microsoft will probably notify you that you can upgrade at some point (Windows 11 will be a phased upgrade, starting on October 5 but not likely to be completed until sometime in 2022). If you want to push things, do a "Check for Updates" every once in a while after October 5, and the Windows 11 update will show up eventually.

I get that. I devoted one computer to testing Windows 11 Beta in the Insider program, but I prefer Stable. I threw the "Unenroll this device when Windows 11 releases ..." switch this morning. I'll get Insider updates until Windows 11 releases, and then I'll be cut over to the release version automatically. I'll upgrade my production computers through the normal process at some point, but I'm not going to push it.

For what it is worth, Windows 11 looks like a solid product from what I can see after several months of daily use.

I'm in no hurry and if I get impatient the Windows update assistant will provide the latest build updates.

Exactly. I imagine Microsoft's servers will be ground into dust for a week or so after release, anyway. I hope you are enjoying your new computer.

Do you really think that ? Microsoft Give support to 8th gen intel and up ... i think more then 50% of the users can't even upgrade. I expect that many users will swap to linux duo their "new standards".
