SOLVED! Im dumb!
Cause: inexperience with bios
Thank you sim, again.

This isnt a problem yet, so just asking in general

So i had to enable CSM in order for my bios to find the nvme SSD i recently installed windows 10 on.
Apparently windows 11 doesnt support csm.
Did I do wrong by enabling CSM when i installed win 10 on the ssd?
How would i go about reainstalling windows without csm, and have the ssd show up? It's all new hardware.
Im gonna have to check if its set up as mbr or gpt, tho i think i selected gpt

Mobo: Gigabyte z790 D rev 1.0
i7 14700k
GTX 1070 (soon to be replaced)
Storage: Samsung 990 2tb m.2 ssd & seagate 2000gb hdd, also got a seagate 1000 hdd available

mbr

#

windows 10 can be mbr windows 11 not, you NEED CSM on for mbr

#

sooo only way for th update would be reinstalling with csm on

#

as it then converts the file system to gpt

blazing nacelle sooo only way for th update would be reinstalling with csm on

but win 11 doesn't support csm ThonkSpin

shit i meant csm off god damit

undone estuary Mar 5, 2025, 10:42 AM

lol yeah i guessed that

blazing nacelle Mar 5, 2025, 10:42 AM

#

like 5hrs of sleep with some stress and now being at school is not the best mix

undone estuary Mar 5, 2025, 10:43 AM

#

In any case i'd have to reinstall win10 first, how would i go about doing that?

#

Without CSM

blazing nacelle Mar 5, 2025, 10:44 AM

#

or just usb stick with windows 11 installer on it and installing windows 11

undone estuary Mar 5, 2025, 10:44 AM

blazing nacelle or just usb stick with windows 11 installer on it and installing windows 11

I guess that works too, but how would i get the ssd to show up without CSM enabled?

blazing nacelle Mar 5, 2025, 10:44 AM

#

it will show up

#

in the installer

undone estuary Mar 5, 2025, 10:45 AM

#

it didnt when i first put in it 🤔

#

that's why i enabled csm in the first place, not knowing that it'd cause problems later

blazing nacelle Mar 5, 2025, 10:46 AM

#

what mode is the nvme in, uefi or raid

undone estuary Mar 5, 2025, 10:46 AM

#

Is that a setting in the bios that i probably missed?

blazing nacelle Mar 5, 2025, 10:46 AM

#

yes

undone estuary Mar 5, 2025, 10:47 AM

#

blazing nacelle yes

It's probably at it's default then, im not sure what that is tho. Give me a moment and ill go look

#

Would you know where i'd find the setting? Im guessing i have to be in advanced settings first

yes i think so

blazing nacelle yes i think so

Soo what do i do, set it to uefi and turn off csm, and see if it finds the drive?

blazing nacelle Mar 5, 2025, 11:06 AM

and you booted into the windows 11 installer usb stick?

undone estuary Mar 5, 2025, 11:06 AM

#

No no, i havent gotten that far

#

Im not installing win11 till octobre or something

#

Tho i guess a win 10 reinstall could be in order

#

I got a win10 stick tho

blazing nacelle Mar 5, 2025, 11:09 AM

#

FFS

#

like i have said many times your windows is in MBR it can only work with csm on

#

anyways just install 11

#

if you can

#

its fine

undone estuary Mar 5, 2025, 11:11 AM

#

blazing nacelle like i have said many times your windows is in MBR it can only work with csm on

This brings me back to my original question again, how would i install windows 11 if my bios cant find the ssd without csm??

blazing nacelle Mar 5, 2025, 11:13 AM

#

thats what i just helped you do

#

you need the usb stick with windows 11 installer plug it in while it is using uefi mode then it should with some hope be able to see the drives

undone estuary Mar 5, 2025, 11:14 AM

#

blazing nacelle you need the usb stick with windows 11 installer plug it in while it is using ue...

So even tho the drives doesnt show up in uefi, they might in the installer?

blazing nacelle Mar 5, 2025, 11:15 AM

#

well the drive is in MBR sooooo in uefi and csm off the drive would you know not be bootable since its still mbr but the install usb should be gpt so it can be seen and the installer is made to install windows 11 so ofc it will be able to be booted into

undone estuary Mar 5, 2025, 11:16 AM

#

blazing nacelle well the drive is in MBR sooooo in uefi and csm off the drive would you know not...

So the installer should be able to convert the ssd to gpt or something?

blazing nacelle Mar 5, 2025, 11:16 AM

#

NO

#

your windows install is using a different file architecture

undone estuary Mar 5, 2025, 11:17 AM

#

So win11 would install as mbr?

blazing nacelle Mar 5, 2025, 11:17 AM

#

NOOOOOOOOOOOOOO

undone estuary Mar 5, 2025, 11:17 AM

#

Well how tf is it gonna install tgen

blazing nacelle Mar 5, 2025, 11:17 AM

#

MBR is csm on only

undone estuary Mar 5, 2025, 11:17 AM

#

Yea

#

But i need to off csm if i install wkn 11

blazing nacelle Mar 5, 2025, 11:18 AM

#

do you have the windows 11 installer usb stick plugged into the pc

undone estuary Mar 5, 2025, 11:18 AM

#

No i still dont have it ffs

#

Im trying to get a hold of one so i can get the installation on it

blazing nacelle Mar 5, 2025, 11:19 AM

#

the only way to install a windows version that supports csm off is by having a usb drive with a windows installer on it and then it automatically detects its in csm off to then install windows in gpt

#

gpt= csm can be off

#

to see drives in the installer then i think the installer needs to be in uefi mode for the drive the thing we changed earlier

undone estuary Mar 5, 2025, 11:21 AM

#

blazing nacelle to see drives in the installer then i think the installer needs to be in uefi mo...

Would i need to do anything with the ssd im inatalling it onto? Its partinioned in mbr atm

#

Huh. For some reason the hdd is GPT, but didnt show up in bios

blazing nacelle Mar 5, 2025, 11:22 AM

#

bios is funky

#

no that one will be fully wiped once windows installes itself again since it needs to rebuild everything

undone estuary Mar 5, 2025, 11:23 AM

#

Oh alright, and it would then also make it GPT?

blazing nacelle Mar 5, 2025, 11:24 AM

#

yes

undone estuary Mar 5, 2025, 11:24 AM

#

Okay

#

Lets say i dont wanna install win11 just yet and push on with win10

Just for a little while

blazing nacelle Mar 5, 2025, 11:25 AM

undone estuary Mar 5, 2025, 11:25 AM

Could you help me install that without csm? Im guessing its the same

#

Oh ok

#

In that case i should have a usb stick ready

blazing nacelle Mar 5, 2025, 11:26 AM

Everything i care about is on the pc, though i could move it to the hdd

Hold on. I was wrong, the SSD im running windows 10 on rn is GPT, the hdd with my games n shit is MBR

It still wouldnt show up in bios
