So i installed archlinux recently and tried to dual boot it with windows 11. But when i boot i dont see the option to login into windows anymore. My windows was UEFI, i turned off fast startup and secure reboot, and also i cant see the windows option in UEFI firmware settings too.

Boot into arch and open your grub config in your preferred text editor
Whats the location of grub config
Nvm found it
hardy osprey
There’s two
gray moth
did you format the efi partition?
quasi scarab
hardy osprey
One gets regenerated after an update so make sure you’re editing the right one
quasi scarab
One gets regenerated after an update so make sure you’re editing the right one
Should i edit this one /boot/grub/grub.conf
quasi scarab
did you format the efi partition?
What how
gray moth
did you format the efi partition?
if you did, then rip windows
hardy osprey
Should i edit this one ``/boot/grub/grub.conf``
Nah you want /etc/default/grub iirc
gray moth
yep
hardy osprey
In there you just need to find the line to enable os-prober
Enable its, save the run grub-mkconfig or whatever it is
I haven’t used grub in a while
gray moth
the line should look like this
hardy osprey
the line should look like this
^
quasi scarab
Yeah i think ive done it already 
hardy osprey
Then when you regenerate your grub config it will look at that line and go hunting for windows
hardy osprey
Yeah i think ive done it already <:empty:904500974767452192>
Try running grub-mkconfig then
You may need to point it to someone I don’t remember
quasi scarab
Try running grub-mkconfig then
Done didnt detect windows
gray moth
can you "ls /boot"?
hardy osprey
Can you still boot into windows from your uefi/bios boot override?
quasi scarab
can you "ls /boot"?
quasi scarab
Can you still boot into windows from your uefi/bios boot override?
no
gray moth
ls /boot/efi
quasi scarab
ls /boot/efi
Blank
gray moth
uhhhhh
hardy osprey
This is unfortunate
gray moth
it should look like this if you mounted the boot partition to /boot/efi?
hardy osprey
I think you formatted your efi partition
Oh wait
Hold up
Run lsblk
See if your efi partition is mounted
hardy osprey
Ok its not mounted
gray moth
so you got this boot partition, whatever this is? and the linux boot partition?
hardy osprey
Run sudo mount /dev/nvme0n1p1 /boot/efi
Then ls /boot/efi
I’m just guessing which one is your efi partition
Os-prober didn’t find it cause you don’t have your efi partition mounted
If the files are there after you mount it you may want to regenerate your /etc/fstab so it automounts in the future
You probably just forgot to mount it during setup
quasi scarab
I’m just guessing which one is your efi partition
gray moth
ok now ls that EFI folder
gray moth
it should look like this if you mounted the boot partition to /boot/efi?
it should look like the bottom one
quasi scarab
ok now ls that EFI folder
GRUB
gray moth
uhhhhhh
quasi scarab
You’re good to regenerate your fstab then
How
gray moth
isn't it supposed to show a microsoft folder?
hardy osprey
isn't it supposed to show a microsoft folder?
Thats inside the EFI folder
gray moth
isn't it supposed to show a microsoft folder?
since that's where the windows bootloader is
quasi scarab
So /boot/efi/EFI/Microsoft
Maybe thats windows 10 idk
gray moth
yes that is windows 10
hardy osprey
what I meant is that it is there he just ran ls on /boot/efi not /boot/efi/EFI
gray moth
what I meant is that it is there he just ran ls on /boot/efi not /boot/efi/EFI
he did run ls on /boot/efi/EFI
hardy osprey
So we’re good
hardy osprey
Look at the screenshot again
hardy osprey
‘ls /boot/efi’
gray moth
i told him to ls to the "EFI" folder
and he replied with "GRUB" which i assume that it is the only folder there
hardy osprey
Whereas in your screenshot you ran ls /boot/efi/EFI
gray moth
i told him to ls to the "EFI" folder when he did ls to /boot/efi
which i also assume that he did "ls /boot/efi/EFI"
hardy osprey
Right, my bad
gray moth
@quasi scarab can you confirm?
hardy osprey
can you send us a screenshot of ls /boot/efi/EFI
quasi scarab
quasi scarab
<@456226577798135808> can you confirm?
Yuh
gray moth
uhhhhhhh
hardy osprey
Is this your only efi partition or is there another one
gray moth
he has like 3?
p1 which is 512m (probably the windows recovery partition?)
p2, the 100M one
and p12, another 512M one
quasi scarab
Yeah
hardy osprey
This is p1
gray moth
no, this is p2
hardy osprey
Oh
gray moth
quasi scarab
Should i mount p1 too`?
gray moth
also the windows boot partition is 100M
hardy osprey
Try unmounting this and mounting p1
Isn’t it usually 500M?
I don’t remember lol
Actually 100M does sound familiar
gray moth
no, windows does 100M
gray moth
yeah it isn't efi
so this is the windows one
and since it doesn't have winddows data, uhhh
hardy osprey
Yeah
quasi scarab
So i should just install it again?
hardy osprey
You’ve formatted it accidentally
hardy osprey
So i should just install it again?
You can recreate it with a windows install usb
No need to reinstall either os
Although the windows installer might overwrite your grub stuff so make a backup (copy the GRUB folder to your home or something)
Only problem is that its a bit annoying to make a windows install media on something other than windows
:pain:
quasi scarab
I think my flash doesnt work after installation
I have to buy a new one
Cuz i cant fix this shit
hardy osprey
Do you have another windows machine
quasi scarab
Yep
