Hmm.
Okay do you know how to access your PC’s BIOS?
indeed
if i disable csm it doesnt run windows
Hmm
Alright
Send me a photo of your bios
wouldnt that mean i have to put windows on a different drive to disable it
Wut
What should I do
Turn off CSM
Turn secure boot off / to custom
It’s other OS or the current option
I can’t or it doesn’t boot into windows
I know
Turn it off
Go to key management
And restore default keys
Okay
and after that just save?
?
No don't
Don't do any of that
Or ur pc will not boot
Don't save any changes
Just exit out of the bios
@J make sure u keep csm ebabled for now
Bet
Loading back into windows

Nah bro whats up with ur windows
Restart ur pc
Do this command again
nope
same thing
Nah we need this to be a primary partition
Go here
Right click on the C partition once
Show ss
This is gonna be a problem
The disk 2 is a dynamic disk
We need to convert it to a basic disk
But that involves deleting every partition present on the disk
And ur windows partition is on the disk
yeah true
Hm there might be a way to convert it to a basic disk using 3rd party softwares
Lemme check
ok ok
So i see this 1 software that can do it
But apparently u need to buy its license
So fuck that
Ok found something else
Bet
Imma be honest i have never worked with this particular software before
But Microsoft support says it can do it without loss of data
Still i am not a 100% sure
ight
Do u have anything important on the disk 2?
not reallyyyy too much
So basically anything important in the C drive other than windows
passwords
steam
etc
Steam can be redownloaded
fuck this imma just clean it and convert it
💀
😭
Can u just copy ur passwords and other important stuff to ur E or D partition?
U will need to reinstall windows then
yeah
Do u have a usb?
mhm
Cuz u can just make a GPT schemed windows if u r willing to reinstall
So u won't have to go through converting it to GPT and shit
yeah imma do it rq
Use rufus to make a bootable pendrive then
Also disconnect ur other 2 drives so u get 0 issues during the installation
Installing windows rn just converted it to gpt format
Are u using a usb?
Yeah
What did u use to convert it to gpt
is that better
or na
So much better
:))
so now what
That was the quickest windows reinstall i have ever seen
Did u have the usb rdy to go or sum
got it on stand by
😂
Is it gpt or mbr
Check for me rq
oh no
...
I mean yea it was expected
i converted it
Using what
diskpart
Where did it let u convert it
when i was reinstalling windows
i cleaned it and did convert gpt
Huh
so when i was installing windows
What did u convert to gpt if there was no partition made in it yet
U went in the recovery environment and command prompt and converted it
I get it
i selected disk 2
and converted it
to gpt
And what was the result
Anyways
Lets give it another go
yeah
