If I do a dual boot of some kind of Ubuntu and Windows, do I get to keep the Windows part as it is now or is it a new installation of Windows? And if I want to make the full switch to Ubuntu, do I then get to keep the installation from the dual boot or do I have to install Ubuntu anew?

Okay, please help me. #TechSupport #Linux I installed pop_OS as a dual boot together with Windows. Now when I go to the file viewer and click "OS" I get an error saying "Error mounting /dev/sdb3 at /media/sagaliciouzzz/OS: wrong fs type, bad option, bad superblock on /dev/sdb3, missing codepage or helper program, or other error"

I'm guessing I should be able to click OS without an error message. Did I make the wrong choices when I partitioned my drive? How do I solve it?

Hah! By fiddling around in the Disks app I managed to get it working :3

Okay, the next addition to "Saga does Linux": yesterday my Bluetooth mouse stopped working. Something about the Bluez daemon not running? After trying to do rfkill and unblock in terminal I read online that it was a known hardware problem with Asus. I did a cold boot and it worked again. Then I got problems with my wifi. Is that because both Bluetooth and my network are on 2.4ghz? My computer was quite far from the router at the time.

@Sagaliciouzzz Nothing will change with your Windows. It will stay the same.

The only thing that will change is that the Linux bootloader (GRUB) will appear when you start your PC. From there, you can choose which operating system you want to boot.

@Sagaliciouzzz För att vara på den säkra sidan skulle jag skafa en till hård disk och installera linux på den, så har jag gjort, windows10/11 på och linux på andra hård diskar, jag har Nobara42, CachyOS, Mx Linux och lobo Linux, så jag gör mer en dual bootar...
@dasra Hm, intressant. Men om jag installerar Linux på samma disk som Windows och sen inte vill ha det så, kan jag avinstallera Linux utan att det påverkar min Windowsinstallation i övrigt?
@Sagaliciouzzz
Då måste du göra en partition som du installerar Linux på, men om du tar bort linux så kommer boot menun ändå visa
linux i menun, bäst ä å köra på separat disk eller usb sticka (installerat dem inte live utan riktig installation), jag kör 2 linux från usb sticka en med Mx linux 128gb och en andra usb sticka med Lobo linux 128gb.
@dasra Okej, så om jag installerar båda på samma disk och sen avinstallerar den ena kommer datorn alltid fråga vilken jag vill starta?
@Sagaliciouzzz
Ja Linux kommer att instalera en boot menu om man bara har windows så kommer den att visa Linux och Windows i i start menyn.
@Sagaliciouzzz
Men bäst är att skaffa en extra hd eller en usb sticka då det finns en risk att om man inte är van att installera ny operativ system att man gör fel vid installationen och råkar installera över windows och då är datan borta.
@dasra Tack för tips! Och om jag installerar Linux på den andra hårddisken så installeras bootmenyn där också? Men om jag sen vill byta från Windows till bara Linux, kommer jag kunna flytta över den gamla installationen an Linux från den externa lagringen till den interna?
@Sagaliciouzzz
Jo en boot meny blir installerat.
Det med att flytta över har jag faktiskt aldrig gjort så det vet jag inte om det går,
Själv så har jag windows 10/11 kvar då det är visa saker jag tyvärr bara kan göra med windows, så Flytta över hm?
@dasra Vad skulle du säga är huvudanledningarna till att du behöver ha kvar Windows?
@Sagaliciouzzz
Då jag inte har BankID i mobilen så
använder jag bankID på fil i Windows då den tyvärr inte fungerar i Linux.
Då visa sidor inte har Freja.
@dasra Jag förstår, tack!
@Sagaliciouzzz You should be able to do both (assuming you have enough free disk space for the first one).
@steven_watt Yeah, otherwise it won't work. But when you say "both", do you mean "have both installed at the same time", or something else?
@Sagaliciouzzz Both = 1) You can keep Windows when you install Linux and 2) You can get rid of Windows without having to reinstall Linux.
@steven_watt Ah, cool! Thanks for clarifying, and for helping me.
@Sagaliciouzzz By the way, if you want to remove the Windows partition at some point but you still need to use certain Windows apps, you can run Windows inside Linux (I use Gnome Boxes for this, but there are several different options).
@steven_watt That is interesting! Do you know if it's hard to remove the Windows partition?
@Sagaliciouzzz Should be very simple to delete the Windows partition and assign the free space to a Linux partition. Getting rid of the Windows option on the bootloader might be a little more complicated.
@steven_watt Cool! Do you mean the menu I can access when I press F2 while the computer is loading? If I boot without pressning F2 it loads pop_OS automatically.
@Sagaliciouzzz OK, it sounds like you're not using a bootloader. Do you have Windows and Linux installed on two separate drives?
@Sagaliciouzzz Anyway that would make getting rid of the separate Windows installation even easier. You could still install it as a "virtual machine" inside Linux and be able to share files, copy and paste, etc with Linux apps.
@steven_watt If I install Windows as a virtual machine Inside Linux, do you think I could use that for the e-id that I've heard does not work with Linux?
Is that some sort of government id that uses a browser extension?
@Sagaliciouzzz Generally speaking, anything that works on a "real" Windows install will work on a Windows VM.
@steven_watt Nope, but on two different partitions on the same drive.
@Sagaliciouzzz See "Installing Ubuntu alongside another operating system" on this page: https://ubuntu.com/tutorials/install-ubuntu-desktop#6-type-of-installation

Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things.

@Sagaliciouzzz If windows was installed first it work out of the box, otherwise it could make troubles. If you don‘t want to use Windows anymore you can delete the windows partition with Gparted to get more disk space. But take care of the boot partiton.
@matking Yeah, I'm running Windows currently but since it refuses to update I'm starting to look at alternatives. Do you mean that I can first partition the drive to have Part 1: Windows and Part 2: Linux, and then get rid of the former but still have the drive in two parts? If so, what are the pros and cons of that?
@Sagaliciouzzz If you run the linux live image and want to install it you can resize the windows partition. I think it will make it all automatic.
But with to separate disk it‘s much easier.
@Sagaliciouzzz if your windows is not full on disk usage, I'll get to keep (probably) the current installation (it was very long time ago I dual booted).
I'm pretty sure, if you like the dual booted Linux (Ubuntu in your case), and you are fully committed, just update GRUB, and extend/move your partition and you removed Windows and you can continue using the already installed Linux.
@blint Thank you, that makes sense!
@Sagaliciouzzz Usually you can keep your old windows installation if you install a dual boot. During the installation process done from a Ubuntu USB stick you are asked how you'd like to proceed.
@Sagaliciouzzz If you consider to have both partitions with an encryption, then you should read this:

How to Dual-Boot Ubuntu 25.04+ and Windows 11 with Encryption

I’ve been writing about how to dual-boot Ubuntu and Windows with encryption for a long time. I first wrote about it back in 2020, where...

@weirdfish That sounds interesting, I'll read up on it before the installation to figure out if I want the encryption or not.
@weirdfish Oh, thank you! So, if I first install Ubuntu on a partioned drive, and then realize I want to remove Windows, should I then run the installation file again and choose to expand the partition to the whole drive?
@Sagaliciouzzz I don't know I never tried it this way. But I think it should be possible to expand the partition with Ubuntu on it from inside of the system.
@weirdfish Sorry, I misread your first response, now I understand. Thank you for your help!
