I’ve tried just the iso, and also Ventoy. I keep getting a ‘key verification error’. It seems I need to turn off Secure boot?
My plan is to eventually just use Linux, but I do want to boot using the iso from USB and verify everything works.
I did some research and found some posts saying with Ventoy you need to register the key, and it will work in secure boot, but it didn’t work for me.
This is a new PC I purchased so I’m a little concerned. I don’t want to risk the current Windows install.
i hade two option when i installed, make sure you pick vtoyefi. You could also try to disable ‘Secure boot’ in your BIOS settings.
Secure Boot and TPM should ALWAYS be off.
TPM can be enabled.
If I turn secure’ boot off, will Windows still boot?
I understand if you install with it off, things are fine, I’m asking about existing install
Yes, it will
If Windows was installed with Secure Boot no it will not boot now. one wqould either rerun Windows or use the one fix out there to make Windows boot again. The latter is not reccommended.
you are ptr1337 are saying the opposite things here, so I am concerned now.
@ptr1337 info on Windows and secure boot is wrong. On top of that Secure Boot and TPM should be off in your bios. Some board have CSM and you want it off as well.
Hi All!
As of July 31st, I just can’t boot on the live ISO and I don’t know why. CSM, SecureBoot and TMP are all disabled. I used BalenaEtcher to flash the USB drive and verified the integrity of the ISO.
What more can I do?
Thanks in advance.
Try OpenSuse Imagewriter and a different USB stick. This program only has 1 button, write, making it difficult to mess up from any sort of user error.
Like in what case not booting? More info about the hardware would be good.
Hi,
I disabled TPM, SecureBoot, CSM and used ventoy. I checked the integrity of the iso. I got to grub, chose an option, the lights on my keyboard and mouse flickered and then lights off and then nothing happenned, waited for ten minutes in case the nvidia driver took more time to load and black screen and the two devices didn’t lights on again.
I have an i7-10700k, 32gb of RAM and a RTX 3060.
I tried with nomodeset, but to no avail. Really bizarre, never had such a problem with any of the live I used so far : Mint, Nobara, etc.
This sounds really weird. I could try to build a fresh ISO with the latest kernel and we can look if it helps.
Actually, having a 4070S and also other users do have a 30xx series and this is quite well tested.
Is there anyway to get logs/pictures from your side?
I find it quite weird too.
What do you want me to provide to you for logs?
I can make a little video to show you what is happening with my phone if you wish.
Hi @ptr1337,
you can download the video I made of the boot process failing : Unique Download Link | WeTransfer
Looking forward to your fresh ISO for me to try it.
Thanks

Here is a new testing ISO. Feel free to test.
Hi @ptr1337,
Still unable to boot on your new ISO. I guess CachyOS doesn’t want me… 
Do you use DVI or so?
Did you try to boot with the non NVIDIA option? several users just tested the iso with 30xx cards and it appears to work fine.
In the 555 driver, there is currently a regression with DVI, that it does not work. Otherwise I really dont know, without any further logs.
Hi,
It’s been a long time since I used command in Linux, so can you remind me how to do that? I know that I have to hit the e key to edit the command line, but what do I have to add? Furthermore, how can I provide you logs?
