rapid stratus Does it boot straight to windows now?

Yes I guess grub has been erased? I need to reinstall it?

narrow oak Aug 1, 2025, 4:35 AM

#

narrow oak Aug 1, 2025, 5:32 AM

#

I launched windows using grub. I rebooted and grub wasn't here any more

#

I tried to reinstall grub with the help of chatgpt but it didn't work

leaden flume Aug 1, 2025, 5:48 AM

#

narrow oak I launched windows using grub. I rebooted and grub wasn't here any more

boot to Windows directly

#

using the BIOS selections

#

once there, check and make sure this is off #1193345280733622272 message

#

then reboot with LInux Mint live USB, and use the boot repair tool in the desktop

narrow oak Aug 1, 2025, 6:14 AM

#

Oh right i disabled it on my computer but no on the laptop

#

In the desktop i only have "install Linux Mint"

leaden flume Aug 1, 2025, 7:00 AM

#

look in menu

#

in 'all applications' or in 'administration'

rapid stratus Aug 1, 2025, 8:27 AM

#

narrow oak In the desktop i only have "install Linux Mint"

Click the menu and start typing boot repair

narrow oak Aug 1, 2025, 8:35 AM

#

Ok i'll try it when I can thanks

#

I tried earlier with the terminal

rapid stratus Aug 1, 2025, 8:50 AM

#

It's hard to say without knowing what exactly you tried. We'll try easier options first

narrow oak Aug 1, 2025, 10:59 AM

#

I tried with the terminal

rapid stratus Aug 1, 2025, 11:49 AM

#

Well when you'll have time ping me

narrow oak Aug 1, 2025, 7:14 PM

#

rapid stratus Aug 1, 2025, 7:39 PM

#

narrow oak hey <@280434352762912768> if you're available tell me 🙂

Ok, first you boot into mint usb

narrow oak Aug 1, 2025, 7:40 PM

#

rapid stratus Aug 1, 2025, 7:40 PM

#

Then click the menu and start typing boot repair

narrow oak Aug 1, 2025, 7:43 PM

#

rapid stratus Aug 1, 2025, 7:43 PM

#

ok

narrow oak Aug 1, 2025, 7:44 PM

#

#

rapid stratus Aug 1, 2025, 7:45 PM

#

Yes, if it's available

narrow oak Aug 1, 2025, 7:47 PM

rapid stratus Aug 1, 2025, 7:48 PM

#

Interesting, first reboot and see where it goes

narrow oak Aug 1, 2025, 7:49 PM

#

i disconnect the usb key when i reboot ?

rapid stratus Aug 1, 2025, 7:49 PM

#

yes

narrow oak Aug 1, 2025, 7:51 PM

#

it boots on windows

rapid stratus Aug 1, 2025, 7:51 PM

#

While you're in windows, check if fast startup is turned on

narrow oak Aug 1, 2025, 7:52 PM

#

i turned it off before booting on the usb linux mint

rapid stratus Aug 1, 2025, 7:53 PM

#

Alright, then go to uefi and show us the boot order

narrow oak Aug 1, 2025, 7:54 PM

#

This ?

rapid stratus Aug 1, 2025, 7:57 PM

#

narrow oak Aug 1, 2025, 7:59 PM

#

i'm on linux

rapid stratus Aug 1, 2025, 8:01 PM

#

Go to the terminal and type

efibootmgr

narrow oak Aug 1, 2025, 8:01 PM

#

i think i used the compatibility mode when i installed linux mint on this laptop

rapid stratus Aug 1, 2025, 8:01 PM

#

and show the results

narrow oak Aug 1, 2025, 8:02 PM

#

Ok, next is

lsblk -f

rapid stratus Aug 1, 2025, 8:06 PM

#

hmm... you have 2 ext4 partitions?

narrow oak Aug 1, 2025, 8:06 PM

#

what is ext4 partition

rapid stratus Aug 1, 2025, 8:07 PM

#

I see. Ok, next type

sudo mount /dev/sda5 /mnt
ls /mnt

narrow oak Aug 1, 2025, 8:09 PM

#

on the same msg on the terminal or two different msg

rapid stratus Aug 1, 2025, 8:09 PM

#

these are 2 separate commands

narrow oak Aug 1, 2025, 8:10 PM

#

#

If you go to discord site and login there, it will be easier to copy commands and share screenshots

narrow oak Aug 1, 2025, 8:11 PM

#

true

rapid stratus Aug 1, 2025, 8:12 PM

#

Ok, sda5 seems to be your linux data, what's sda7 then? Do this:

sudo umount /mnt
sudo mount /dev/sda7 /mnt
ls /mnt

narrow oak Aug 1, 2025, 8:17 PM

#

rn_image_picker_lib_temp_92eb7a3e-f1af-4594-976a-27a1ed6287e5.jpg

#

and it opened LINUX MINT THunar

rapid stratus Aug 1, 2025, 8:19 PM

#

That's something else.... maybe you setup separate home for some reason, either way sda5 is your system partition

#

Do this next:

sudo umount /mnt
sudo mount /dev/sda5 /mnt
sudo mount /dev/sda2 /mnt/boot/efi
ls /mnt/boot/efi

narrow oak Aug 1, 2025, 8:22 PM

#

ok i've EFI in blue

rapid stratus Aug 1, 2025, 8:22 PM

#

screenshot please

narrow oak Aug 1, 2025, 8:22 PM

#

rapid stratus Aug 1, 2025, 8:23 PM

#

ok, while we're here, show us

cat /mnt/etc/fstab

narrow oak Aug 1, 2025, 8:24 PM

#

rapid stratus Aug 1, 2025, 8:25 PM

#

Ok so sda7 is home folder

#

Alright, next do this

for i in /dev /dev/pts /proc /sys; do sudo mount --bind $i /mnt$i; done

narrow oak Aug 1, 2025, 8:26 PM

#

i think i did a partition for linux and one for the documents

#

rapid stratus Aug 1, 2025, 8:28 PM

#

no errors, good. Next do

sudo chroot /mnt
sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi
sudo update-grub

narrow oak Aug 1, 2025, 8:29 PM

#

rapid stratus Aug 1, 2025, 8:31 PM

#

hmm.

#

Do

ls /boot/efi/EFI/

narrow oak Aug 1, 2025, 8:33 PM

#

leaden flume Aug 1, 2025, 8:33 PM

#

narrow oak

i dont think he meant type it literally here.

#

kek

rapid stratus Aug 1, 2025, 8:36 PM

#

ok, then do

sudo rm /boot/efi/EFI/ubuntu/*
sudo rmdir /boot/efi/EFI/ubuntu
ls /boot/efi/EFI/

leaden flume Aug 1, 2025, 8:36 PM

#

leaden flume i dont think he meant type it literally here.

i dont think this was done properly

narrow oak Aug 1, 2025, 8:37 PM

#

root@mint:/# sudo rm /boot/efi/EFI/ubuntu/*
rm: cannot remove '/boot/efi/EFI/ubuntu/*': Not a directory

rapid stratus Aug 1, 2025, 8:37 PM

#

leaden flume i dont think this was done properly

What exactly?

leaden flume Aug 1, 2025, 8:37 PM

#

look at pic

#

attached

#

for i in /dev /dev/pts /proc /sys; do sudo mount --bind $i /mnt$i; done

#

they typed that in literally

rapid stratus Aug 1, 2025, 8:39 PM

#

I don't see the problem?

leaden flume Aug 1, 2025, 8:39 PM

#

is for an actual command?

narrow oak Aug 1, 2025, 8:40 PM

#

rapid stratus Aug 1, 2025, 8:40 PM

#

Hold on @narrow oak

leaden flume Aug 1, 2025, 8:42 PM

#

I'm surprised boot repair didn't already fix it

rapid stratus Aug 1, 2025, 8:42 PM

#

leaden flume is *for* an actual command?

As I understand that command is supposed to do the same as binding /proc /sys and stuff no?

leaden flume Aug 1, 2025, 8:42 PM

#

it seems it did, as in it made a grub efi and ubuntu folder

#

but it's not showing in BIOS cuz of dumb bios

#

probably have to look in BBS UEFI priorities

#

some are so shit they hide it there

rapid stratus Aug 1, 2025, 8:43 PM

#

Still, I'd like to reinstall grub manually here

leaden flume Aug 1, 2025, 8:44 PM

#

yeah go ahead

rapid stratus Aug 1, 2025, 8:44 PM

#

narrow oak

@leaden flume But it says it can't create ubuntu folder, although it's there?

#

So.... I'm trying to remove it first

#

@narrow oak do

ls /boot/efi/EFI/
ls /boot/efi/EFI/ubuntu/

please

narrow oak Aug 1, 2025, 8:47 PM

#

rapid stratus Aug 1, 2025, 8:48 PM

#

hmm.... try

ls -l /boot/efi/EFI/

narrow oak Aug 1, 2025, 8:49 PM

#

leaden flume Aug 1, 2025, 8:49 PM

#

ubuntu is in green, so ... whatever it is, (probably an executable) it's not a directory

#

no d at the front. definitely not a directory

rapid stratus Aug 1, 2025, 8:50 PM

#

Ok... @narrow oak then do

sudo rm /boot/efi/EFI/ubuntu
ls -l /boot/efi/EFI/

narrow oak Aug 1, 2025, 8:52 PM

#

rapid stratus Aug 1, 2025, 8:52 PM

#

leaden flume ubuntu is in green, so ... whatever it is, (probably an executable) it's not a d...

Could it be that the d flag got removed somehow so mint thinks it's a file now?

#

@narrow oak do

sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi

narrow oak Aug 1, 2025, 8:54 PM

#

rapid stratus Aug 1, 2025, 8:55 PM

#

and do

sudo update-grub

narrow oak Aug 1, 2025, 8:57 PM

#

rapid stratus Aug 1, 2025, 8:57 PM

#

ok, next do

exit
ls /sys/firmware/efi/

narrow oak Aug 1, 2025, 8:58 PM

#

on two commands ?

rapid stratus Aug 1, 2025, 8:58 PM

#

yes 2

narrow oak Aug 1, 2025, 8:58 PM

#

rapid stratus Aug 1, 2025, 8:59 PM

#

Ok.... next is

sudo umount -R /mnt

narrow oak Aug 1, 2025, 8:59 PM

#

tell me this is positive haha

rapid stratus Aug 1, 2025, 9:00 PM

#

If there are no errors after the last command, remove usb and restart

narrow oak Aug 1, 2025, 9:00 PM

#

rapid stratus Aug 1, 2025, 9:01 PM

#

yeah restart

narrow oak Aug 1, 2025, 9:02 PM

#

it boots on windows

#

do you want me to check on the bios if I can start on grub ?

rapid stratus Aug 1, 2025, 9:03 PM

#

Show us uefi settings, not the boot menu

leaden flume Aug 1, 2025, 9:03 PM

#

yep. u gon' have to dig deep in there.

rapid stratus Aug 1, 2025, 9:04 PM

#

narrow oak

@leaden flume This bothers me, although usb booted in uefi mode

narrow oak Aug 1, 2025, 9:05 PM

#

rn_image_picker_lib_temp_80564e29-1eab-4779-9266-3acda1d54693.jpg

#

Ubuntu is back here. It wasn't here earlier

leaden flume Aug 1, 2025, 9:05 PM

#

narrow oak

this may be another way of saying NVRAM locked, same as what boot repair said.

rapid stratus Aug 1, 2025, 9:06 PM

#

narrow oak

place ubuntu first

leaden flume Aug 1, 2025, 9:06 PM

#

yup. move to top, then save/exit

narrow oak Aug 1, 2025, 9:06 PM

#

Ok done.

rapid stratus Aug 1, 2025, 9:07 PM

#

and see if that boots

narrow oak Aug 1, 2025, 9:07 PM

#

hallelujah

rapid stratus Aug 1, 2025, 9:07 PM

#

Finally

narrow oak Aug 1, 2025, 9:08 PM

#

rn_image_picker_lib_temp_22d7661a-625e-43ca-a193-65d1f598417a.jpg

#

But why don't I have windows here ?(Anyway i don't wanna go there any more)

leaden flume Aug 1, 2025, 9:09 PM

#

maybe windows is in legacy

#

in which case, you'd need to boot it straight from BIOS boot menu

#

or maybe not.

narrow oak Aug 1, 2025, 9:10 PM

#

My session is back thanks a lot 🙂

rn_image_picker_lib_temp_cbf6070b-5927-4e20-8d85-e21072025032.jpg

leaden flume Aug 1, 2025, 9:10 PM

#

it did have a Microsoft folder in EFI

#

just run sudo os-prober from here and see if it finds it

narrow oak Aug 1, 2025, 9:12 PM

#

It says
/dev/sda2@/EFI/Microsoft/boot/bootmgfw.efi:Windows Boot Manager: Windows:efi

leaden flume Aug 1, 2025, 9:13 PM

#

then do sudo update-grub and watch it carefully

#

it should add that new-found entry into the grub menu

narrow oak Aug 1, 2025, 9:14 PM

#

yes it says found windows boot manager ...
adding boot menu entry for uefi firmware settings
Done

leaden flume Aug 1, 2025, 9:14 PM

#

that's it then

rapid stratus Aug 1, 2025, 9:14 PM

#

Alright, restart and see

narrow oak Aug 1, 2025, 9:15 PM
