Need linux distribution to boot in UEFI enabled pc's?
I installed a linux distribution with the UEFI enabled pc, but in the first boot to login to the os get this bios error message:
Code:
Manjaro secure boot error: operating system had no valid singnature, incompatible with secure boot.
and only option was to shutdown the pc, is there any linux distribution to boot to UEFI enabled pc's.

Majaro is, as well as most other Linux distros. Manjaro even has a UEFI installation guide on their website:

Every distro currently being actively developed supports UEFI. secure boot =/= UEFI. Secure boot RELIES on UEFI, but is NOT the same as it.

Is there any reason why you can't disable secure boot in your UEFI BIOS settings? As I can't seem to find anything that says Windows actually requires secure boot to boot, if that's what you're worried about.
You may also be able to backup the keys to a USB stick from your UEFI BIOS settings to restore them later on if you want/need to.

So does Windows still boot if you disabled secure boot (I don't have Windows to verify for myself - being the reason I'm asking the question)? Like I said before, I can't find anything that explicitly says something to the effect of "Windows needs secure boot enabled to boot".
The way I see it, you have two options:
1. Disable secure boot in your BIOS settings
2. Install a Linux distro that fully supports secure boot - they do exist. Ubuntu comes to mind.

I am using linux and windows 10 in the legacy mode since years, but some one told me the UEFI is good to be enabled, so i get the idea to do so,
I read the arch wiki about UEFI and did some steps now manjaro boot in secrue boot and taking me to the MOK manager window, now i am stuck here and trying to read further how to manage this MOK manager window.

You seem to be confusing UEFI and Secure Boot. They are two different things. See also the third answer to your question.
Linux has no problem with UEFI, but often with secure boot. This is why you have been asked several times to disable secure boot.
You ask about distros that support UEFI. You should ask about distros that support Secure Boot, for example Ubuntu. I am sure the other enterprise distros Centos, Debian and OpenSUSE do as well.

Is windows and manjaro already installed in legacy mode? If this is on a system with windows and manjaro already install in legacy mode, leave in legacy mode. Don't try to convert.

reFind? Is this a Mac you're installing on? If so, would have been good to mention that at the start...install procedures are different for Macs.

Having to disable secure boot is NOT the same as not supporting UEFI. That's like saying "I'm not running linux, I'm running Ubuntu". It's still Linux, and by the same token, almost every active distro STILL supports UEFI. Just not all distro's have worked with MS to get their kernels signed to support secure boot.
