@Parto Sometimes they even omit .

Parto

@Kulfy omit?

Kulfy

.

They just run chmod -R 777 / with sudo.

Parto

Oh, yeah. Hahah. that's now funny and very dangerous

I am glad to be in the ./ category especially for apache (php) permissions

Kulfy

12:38

@Parto I'm not sure why it reminded me of Rush Hour 3

@Kulfy which will effectively brick your system in terms of administration as sudo and the like wont run properly anymore

alright, not sure if this is the right place to ask this, but I didn't want to make another "ubuntu won't boot" question - I'm installing Ubuntu on a Lenovo c940 alongside Windows and I can't get it to run grub no matter -what- I do

I've tried the liveusb with default settings, I've tried it with funky settings... I have no idea why I don't get a grub, it doesn't even show up in the bios

Ravexina

You should create a new question describing what you already did...

Owen Versteeg

alright! Didn't want to add to the million and one "no grub" questions but I guess that's the best thing to do here

Ravexina

If none of the answers to already posted questions can help you then you are probably facing something different...

jokerdino

@OwenVersteeg does the liveusb actually boot?

Owen Versteeg

yep!

Q: No GRUB after trying to dual-boot Ubuntu and Windows 10

So I've tried to install Ubuntu using the 20.04 liveusb, and I can't seem to get it to boot. I'm pretty sure this is related to some sort of bootloader problem - either installed in the wrong place, or in the wrong way. I've tried: Reinstalling using the liveusb the Boot-Repair software (I didn'...

just posted it as a question

the liveusb is just fine, works great, boots, no errors or anything during the installation process, tells me to reboot, which I do... and then I find zero ubuntu

jokerdino

16:00

so when you start your computer, it boots straight to windows?

Owen Versteeg

yep, exactly

and there's not even an entry in the bios for any grub/ubuntu/anything, just one entry for windows

jokerdino

is it in legacy mode or uefi mode or whatever that is

Owen Versteeg

Well I've turned off uefi

so I... think it'd be in legacy mode?

Zanna

@OwenVersteeg why did you do that?

Owen Versteeg

well, actually, I didn't, my boss did when he started this process

Owen Versteeg

but then I said I could do it, and now I have egg on my face

Zanna

(I don't mean "OMG what a terrible thing to do!", it was a real question)

Owen Versteeg

Hahahah yeah

The funky thing is I can't seem to turn it back on

jokerdino

i also am running on legacy mode

Owen Versteeg

There's a section in the (very modern and weird looking) bios that has an option for Secure Boot. He put it on Disabled, I tried putting it back on Enabled and that ... still didn't turn it on

jokerdino

16:17

disable CSM

Zanna

RAID

I know nothing

Owen Versteeg

what's CSM and where would I disable it? I'm in the bios now and I see nothing

Zanna

your Ubuntu partition is mounted on /tmp/...? or I'm just really bad at reading boot-repair info

Owen Versteeg

uh I think that's just the liveusb mounted on /tmp

Me too, boot-repair is a bit tricky to understand

I thought maybe one thing to do is to chroot and try to muck around with grub-install there?

jokerdino

luckily i am not a boot expert

Zanna

16:26

@OwenVersteeg I'm looking at this line

nvme0n1p5                                                362.2G   1% /tmp/tmp.rvPRnigEaf

Owen Versteeg

Yeah I ran boot repair while I was on the liveusb

so I thiiiink that's it?

but it's very likely I am completely wrong

discussion

Zanna

It's an ext4 partition of ~362 GB size

I think sda is your live USB in this report

anyway I don't know what the significance of it being mounted there would be :(

@OwenVersteeg the option disappeared?

if you turn it back on, you might see a boot option for Ubuntu

Owen Versteeg

oh that's funky, huh

Zanna

whether that option will work or not... :S

Owen Versteeg

16:34

@Zanna I've rebooted a few times now and still no boot option for anything but Windows

Actually I did get a network boot option when I plugged in a USB-C -> ethernet cable

Zanna

I mean in the BIOS/UEFI settings

Owen Versteeg

yeah nothing in the BIOS settings

Zanna

:/

Owen Versteeg

there's a section "boot" and in there there's a heading "EFI" and under that I only see "windows boot manager"

Zanna

are there some other settings to switch between legacy support and UEFI or something?

how did you make the live USB?

but anyway you were able to boot that, so changing it probably won't help

Owen Versteeg

16:38

There is an option to enable or disable secure boot

My boss disabled it, I first left it on disabled, then tried enabling it

but for whatever very weird reason, "secure boot status" (a little bit of text under that) remained "disabled"

Zanna

secure boot only works with UEFI I think

so if you disabled UEFI I don't think you can enable secure boot

Owen Versteeg

Yeah I think so

Zanna

I could be misremembering that though

Owen Versteeg

but I didn't disable UEFI as far as I know

Zanna

oh

I thought that was what you said your boss did

sorry

Owen Versteeg

16:40

Oh, I meant he disabled secure boot

Zanna

yes... usually that helps

I have never had any luck booting Ubuntu with secure boot on. But others have managed it :)

Owen Versteeg

alright, maybe the best thing to do is to just wipe the windows partition, then install windows from scratch at a later date?

jokerdino

@OwenVersteeg eww no

Owen Versteeg

yeah I figured that would be painful as hell

damn

jokerdino

just wipe it and forget about it

Zanna

16:41

well, if Ubuntu doesn't boot now, there's no reason to expect it to do so after you kill Windows

jokerdino

👍

Owen Versteeg

well it does need to have both windows and linux on it somehow

jokerdino

oldfred the expert is there

Zanna

:)

Owen Versteeg

Ooh I like the sound of that

Zanna

16:43

I can sign off haha

Owen Versteeg

Oh, you're being helpful too!

Everyone is, I think this is just a particularly funky case I've gotten myself into

I have a feeling the "optane" is complicating things significantly

Zanna

I'm just happy someone who actually knows installation stuff arrived on the scene

RAID is funky I think :/

Owen Versteeg

I thiiiiink it's not RAID anything?

As far as I can tell the optane thing is just a caching sorta device in front of the ssd that keeps frequently used stuff

so it might be holding the bootloader? perhaps?

or maybe it isn't, but it should be?

Zanna

16:57

you have got RAID stuff in your boot-repair report

oldfred is saying switch to AHCI in BIOS, after installing AHCI drivers in Windows

Owen Versteeg

Ooh nice, I'll try that

Zanna

fingers crossed

Owen Versteeg

alright, so I'm in Windows, where do I get some ahci drivers? This is a Lenovo C940

Zanna

wish I knew :S

Owen Versteeg

do I want the Intel SATA Controller AHCI Driver for Windows 10?

That sounds right-ish

ah just kidding that was for a helix something?

Zanna

17:11

sounds promising

I mean I'm looking up how to do it and some of the procedures I find mention that thing

Owen Versteeg

nah that was for some other hardware

so there's an AHCI option in my bios

Zanna

yes good

Owen Versteeg

without having installed anything

Zanna

but if you enable it, Windows may not boot

Owen Versteeg

but it warns me all existing data on the drives will be erased

so that isn't totally ideal

Zanna

17:11

yeah

that's another thing that could happen

Owen Versteeg

so if I do this I format my entire hard drive?

Zanna

that's why you have to do something in Windows first

@OwenVersteeg ideally no

Owen Versteeg

ah hmm

ah also if I do this I lose the acceleration from optane?

that's not ideal either

Zanna

@OwenVersteeg no idea at all

I think the procedures suggested in this answer do what oldfred is suggesting

but if you have anything you need presumably a backup would be very advisable

and I have no idea whether it would affect that extra drive

looks like quite a complex problem

after you fix it, you can explain it all to your boss and impress them with jargon B)

Owen Versteeg

Well, the bios tells me I lose optane if I switch it to AHCI no matter what I do

Zanna

17:22

oh :/

Owen Versteeg

but there's got to be a way to do it just... normally?

other people appear to have been able to actually install linuxes on this thing

without sorcery

Zanna

I always hear about other people installing stuff and it Just Worked™

Owen Versteeg

17:41

oh no, now I get an error when trying to boot the liveusb

40% of OpenBSD installs lead to shark attacks. It's their only standing security issue.

jokerdino

@OwenVersteeg never been not relevant

Owen Versteeg

how did I even get to this point

where my liveusb doesn't work, my optane is gone and my sanity is lost

jokerdino

at least you still have a job

I guess

Owen Versteeg

Well not after everyone learns it took me a few hours to do something as simple as install ubuntu off a liveusb

jokerdino

did they all install it on a lenovo?

Owen Versteeg

17:49

well everyone here has lenovo something but they're all a bit older and more sane

before intel decided to add ram-ssd-raid-things to everything

jokerdino

@OwenVersteeg that's their fault

Kulfy

@Videonauth YES

Owen Versteeg

19:38

So, for anyone who was curious how my problem ended up: turns out that disabling Optane is the only sane way to do this. Once Optane is disabled, it's fairly straightforward.
