Windows 10 and RHEL 9 Dual Boot help.

Re: Windows 10 and RHEL 8 Dual Boot help.
Hi Everyone,
May you kindly help with the following boot issue. I had Windows 10 on an Lenovo Ideapad 3. I then added RHEL 9 in order to have a dual boot setup. I used the RHEL installation for a few hours then rebooted to Windows 10. Now I want to reboot to RHEL but RHEL is not listed on the available operating system options. Only Windows 10 is appearing. What can I do to make RHEL available?

Was this starting from a boot? Is it possible that you hadn't installed yet and were just running live?

My thought as well.

@scottalanmiller I started from boot. While in Windows 10 I can see the partition containing RHEL. Its marked as primary

@Pete-S When i rebooted from Linux, I actually selected Windows 10 from the list of available operating systems

Sorry, I can't help you. I stopped trying to get Windows and Linux to coexist on the same drive with dual boot because Windows would often cause some problem even when it's suppose to work.
So when I need windows and linux on the same machine I do one of three things:
- run the secondary OS in a VM and then both OSes can run at the same time
- install each OS on it's own drive and swap drives as needed
- have windows installed but boot linux from a USB drive without actually installing it

Agreed, running a VM on either Windows or Linux is such an easy thing to do now that dual booting really doesn't make sense any more.

@DustinB3403 & @Pete-S Thank you so much. I have installed VMWare on Windows 10 and all seems well so far.

Agreed, this is what I'd do too.

I prefer the other way, Linux on the metal, use KVM built in, and Windows on top. Faster, more stable, and then it's Linux that's "faster" and always there. But I use Linux as my main operator and Windows purely for testing things so.... makes more sense for me.

A lot of PCs come with OEM Windows license keys in the BIOS. I don't think you can use that license when you run the OS in a VM. At least not automatically.
So that favors Windows as the base OS.

Can use, but not automatic, in all cases. I've had cases, I'm pretty sure, where it worked automatically.

@Pete-S Any Windows 10 licence will technically work in VM, from my experience.
But you need special licences to run W10 in VM if you want to respect MS licensing (W10 Pro or W10 Home license does not give you right to run in VM)
Old Windows 7 licenses were eligible to be run in VM.
Here is description of Win10 virtualization licenses:

Yeah, but we're talking about the embedded license key that sits in the BIOS of the computer (when it comes with Windows OEM).
In a VM the guest can't access the BIOS of the host so it shouldn't be able to retrieve the embedded Microsoft licensing key. Unless the hypervisor makes it available to the guest.
The embedded licensing key is used automatically by the Windows installer and it will install Windows without asking the user for a key.
Back in the day there would be sticker on the bottom of the computer with the licensing key. But now it's stored in the BIOS somewhere and the sticker only has a windows logo on it.
