This one is lovely!

But, ehm.. Lionel, are you ok? They typically don't do this just for fun I think?

Yes, it turns out that my specific laptop is a really poor choice for trying this out. It's got an AMD cpu, AMD iGPU and NVIDIA dGPU.. Which makes Fedora choke on install with an 'unknown error', Ubuntu freezes while booting the installer, and several other options have similar (fatal) issues.

That is super unfortunate then for Linux acceptance (on laptops). If you're a long-time Windows user like me, getting annoyed with MS and slowly edging towards Linux, you *need* dual boot just to make the transition. If that is a pain, I have to stay with Windows. I can't transition overnight.

Hm no there's just one slot. I was planning on giving each OS their own partition, but all the outlined problems were with that setup. Trying Ubuntu now, will add Manjaro to the list. :)

O cool, there is space for a second drive? Didn't know that, I have a couple of spares. :)

I was avoiding it because some sites reported compatibility issues. It seems those are related to audio (working, but muffled) but that hardly seems an issue for my needs so I will give it a shot! Thanks. :)

Thanks, I will check that out! I do realize I have new HW, but on the other hand: The Zen/4070 combo has been available since 2022 and this is just an iteration on that theme (I have 5080). It's not really dual-gpu btw, but it is indeed odd to combine Zen with RTX.

After some responses here I tried Fedora. This is with default options, installing to 500GB unallocated space on an SSD that contains Windows in the allocated space. Sigh.

I'm not just trying it out, I want it to slowly transition from Windows to Linux on my main machine, so that I know I can do my work, while also using my work to slowly get used to the new OS. That isn't too outlandish I think?

Yes I see my mistake now, will go for Fedora!

BIOS setup is not too hard for me. But MS does not require changes there, so why does Linux? Will mint or fedora come with properly signed isos?
My point is that acceptance by the general population requires a smooth, comforting process, otherwise it's power user-only.
Will try Fedora now. :)

How does 'Linux' expect to become mainstream when the install process is this painful? I am not a novice user (I like to believe) yet it is so far impossible for me to do this. Should I pick a more mainstream distro? Or is this a common problem? It's sad, I really want this to work...

6/6

At first the USB containing the ISO wouldn't boot at all. To make it boot in the first place, I had to *go into the BIOS and disbale safe boot*. WHAT. I trusted that ISO with my SSD and it worked, but... REALLY?

TL;DR in final text...

5/6

Luckily a hard cold reboot gets me back to Windows. Second attempt: I disable the screen timeout. It now completes, but: It can't install the bootloader. Reason unknown. By the way, I forgot an important thing:

4/6

Install process: Ouch. The screen is '3K' so the font is tiny. I grab my glasses and continue. It wants to know A LOT before it even begins. Then it starts installing. After 5 mins: Screen blanks (energy saver). And doesn't come back. While my partition table is being molested. I'm scared.

3/6

I picked CachyOS because, well, it sounds catchy, mentiones 'performance' a lot and seems to be a great option for my brand new Asus G14 (thank you #asus for awesome hardware!). Obviously, I want to install next to windows, so I prep a 512GB partition on the SSD.

2/6

I'm in the middle of my yearly attempt to ditch windows and install Linux, for the usual reasons (in this case: welcome screen ads and stock option graphs that I didn't order).

And once again I failed. Short, sad, true story.

1/6

What builder are you using? Can I help you with those bugs?

O wow, that one is particularly beautiful.

I love this experiment.

At SIGGRAPH 2025, Intel, Disney, & Chaos are doing a course on the nitty gritty details of implementing path guiding methods in 3 production renderers: Cycles, Hyperion, and Corona. I helped write the course notes: 80 pages of great stuff! Coming soon.
