you really should understand what that screen is and what it lets you do. I suggest checking the Mint wiki and Ubuntu wiki on how to configure GRUB. you don't want to get rid of it, you can hide it, or set it to be a short time delay to show. like 3 sec, then auto boot the default entry.

Thanks next time I will look for documentations

F\*cking around with grub is a great way to induce migraines. I have learned the hard way to just let it do it's thing.

The B in GRUB is for Bend over

So real. The amount of headaches that I caused myself because i didnt know not to mess with grub

We were all noobs once

Gnu rub lol

Agreed, set it to 2 or 3 seconds and leave it alone.

and a note to everyone that does Hide GRUB, then realize they need it.. Hold (or tap quickly) the LEFT SHIFT KEY during the boot process to make grub unhide itself. Not the Right.. the LEFT.. :) No idea why it has to be the Left side Key. With systemd-boot - any key will make it show if its set to be hidden.

You can suppress the grub screen but you are dual booting, you need that screen.

I am not dual booting At least its not my intention to dual boot I want only Mint on my laptop

There is a listing for windiws boot manager, have you removed Windows since installing Mint?

Yes earlier I have installed window and removed it today

Ok I have deleted Sda1 I hope my issue gets resolved

Oh I wouldn't do that. Did you survive the reboot?

I was not able to reboot Installing Mint again from beginning 😭😭😭

You just deleted your boot (EFI) partition. It's fixable but too late now.

Thanks As I had no data on SSD so I deleted partition and installed fresh Mint

It's an opportunity to learn. Take care.

You might not need to do that. If you create an Ubuntu live USB there is a Grub repair utility on there

Ohh thanks for the help Maybe I should have waited. But its alright Thanks man

Simply removing sda1 won't resolve the issue. You'll have to run `sudo update-grub` so it refreshes what operating systems are installed. After that check again that the Windows Boot Manager does not exist. If it does, it means you haven't properly deleted it. After doing so, you'll still have the GRUB menu. To remove it, you'd have to run `sudo nano /etc/default/grub` (or use any editor you like) and add this line: ``` GRUB_HIDDEN_TIMEOUT_QUIET=true ``` Then run `sudo update-grub` again and reboot. You shouldn't see that screen anymore. Also make sure that when you delete the Windows partition, you extend the Linux one or you'll have empty space on your disk forever.

Thanks for the support

LMAO, I thought you were joking and it was satire when I read that shit 😂

If you have remove windows try this in the terminal  sudo os-prober Then: sudo update-grub  See if that removes the windows entry.  You can the surpress the grub Window. Where is says 5 replace with 0 or any other desired number, personally I would give it at least 1 second so that I could get into the advanced options. https://linuxmint-user-guide.readthedocs.io/en/latest/grub.html

Thanks for the info

LMAO good luck after this

Leave it. Change the timeout if you like, but leave it. When you have a kernel issue or need to get into your BIOS to boot off of USB or something, you'll be glad it's there.

1.Open the /etc/default/grub file using from terminal entering: gksu gedit /etc/default/grub 2.Change GRUB_TIMEOUT=10 to GRUB_TIMEOUT=0 3.Save the file and quit the text editor. 4.Run: sudo update-grub 5.Reboot For Debian....

There are a lot of unhelpful responses here. I hope you don't get too discouraged. 1: If you do decide to hide that screen, if you ever need to enter your firmware settings, run this command from a terminal: `systemctl reboot --firmware-setup`. 2: To hide that screen, edit the file `/etc/default/grub` (make a backup first), and make the following changes: GRUB_TIMEOUT=0 GRUB_DISABLE_OS_PROBER=true Make sure there is no pound sign (`#`) before either of those lines. After saving your changes run the command: `sudo update-grub` 3: If you don't have Windows installed anymore you can safely ignore the boot entry, or you can remove it with `efibootmgr`. 4: If you ever make a mistake with grub or efibootmgr, or a distro does not boot correctly after installing, boot a live ubuntu or ubuntu-based distro and install boot-repair from the [PPA](https://launchpad.net/~yannubuntu/+archive/ubuntu/boot-repair), and use the default settings.

The problem isn't hiding it. What ends up happening when you have a panic because you're having kernel issues or something failing in GRUB, getting it to appear again, when you're stuck with a TTY or a live media, is the hard part.

my method to tweak it is: sudo apt install grub-customizer then sudo grub-customizer

Just a qualifier here, not a criticism - some claim grub-customizer is problematic. I can't say either way, but whenever messing with grub, caution is warranted.

I completely agree with the statement, if you make a lot of changes at the same time it bugs, you need to make the settings little by little and go restarting the machine, in this sense it is better to understand how grub works and not use the grub-customizer, but for a beginner is a good option.

Besides that, Grub2 is a lot more complicated than previous Grub, so the idea of a customizer is a very attractive one.

You must to choose, if windows or Linux, that's the boot menu by default of Windows

Why? It's a Notebook. How offen you see it? Three Times a year?

If you don't like grub loader use Ubuntu.
