Dual Booting

I want to dual boot Linux and Windows 10. Linux for work, Windows for gaymen because I am a manchild. Are there any security risks involved? Can Windows somehow see and/or access what I do/have on the Linux partition? Enlighten me on dual booting.

Yes, it can.

If that was the case, there would be no point in dual booting and using any linux distro for daily browsing/media/learning.
So I hope not.

If u have uefi, grub won't run. So, u can install linux and windows on different partitions and when grub will start, you will have opportunity to choose between win and linux.

I take it uefi is the security risk, associated with using this configuration?

It's not a risk (if i understand the determination of security risk right)

suppose i have dual boot
If i get a virus in one of the OSes, will the other OS be fine?

Yes, assbutt. Especially if they're different operating systems.

It should be fine. Windows can't read ext filesystems. Even if it can secretly, just encrypt your Ubuntu installation at the system level.

>Can Windows somehow see and/or access what I do/have on the Linux partition?
Not if you encrypt the partition and boot with GRUB. You should probably install one OS per physical disk so that Winshit update doesn't write over the partition table and wipe out GRUB. If you encrypt the main Linux partition there's no why that Windows can get into it unless you were to install drivers for EXT3/4, XFS, or whatever file system it's using and unlock it FROM Windows itself, since NT would be then handling the decryption program.. The only time you should be entering your password for the Linux disk is when booting into it, because the Linux kernel handles the decryption in that case.

Of course you are still left vulnerable to the BIOS and Intel ME or AMD PSP. The BIOS, especially certain EFI or UEFI implementations, can interface with the kernel in fucky ways. Pottering is an ass so the UEFI variables on distros with systemd are always left read/write by default. At the very least I have heard that some motherboards from MSI have no way of recovering these if you delete them, so you'll get a bricked board. The other thing too is security co-processors like the Intel Management Engine or AMD Platform Security Processor. The Intel ME can do all sorts of nasty stuff and runs at ring -3 in your system. The firmware for it is located on the same ROM chip as the BIOS firmware so it has full read/write access to that, meaning someone that can exploit the ME can implant a permanent rootkit in your hardware. The ME can hook into OS network stacks in at least Linux and Windows and can set up its own in memory if no OS is present, and it does so through AMT. The PSP on the other hand is poorly documented and has no official uses outside of doing hardware based security functions for UEFI secure boot, which makes me very suspicious of it. I choose Intel for my x86 needs because it's the evil I know. To mitigate the ME cancer you can use ME_Cleaner and Coreboot.

>Are there any security risks involved?
Yes, it is a big security risk. If you don't trust Windows (and you shouldn't), NEVER run it on bare metal with access to every fucking bit of hardware you have connected. Fuck that shit.

>I want to dual boot Linux and Windows 10. Linux for work, Windows for gaymen because I am a manchild.
user, what you actually want to do is run Linux on the bare metal, and contain Windows in a locked-down virtual machine where it belongs. Only run the minimal amount of software in the VM. Games, sure. Chat programs, emails, etc. fuck no. Disable internet access for the VM entirely if you're only playing offline games. Look up GPU passthrough to get near native performance, and look up KVMFR (Looking Glass) to make it virtually seamless.

There is software out there that you can install on Windows to read ext filesystems. And even if Windows doesn't openly offer any feature like that to users, that doesn't mean it can't still read the files behind the scenes. You think the NSA/CIA wouldn't have thought of that already?

If you want to dual boot, the best choice by far is to have two separate hard drives. That way, there is a lot less risk of having either system fuck with the other one's partition.

>Running Windows in bare metal ever
user, if you've ever run Windows on your computer you need to buy an entirely new computer. Running Windows just once is enough to compromise it - or at least you have no way of knowing. Windows could fuck with your motherboard's UEFI, the firmware of your SSDs, the BIOS of your graphics card, or anything else. Who knows what it's done? Even if you wipe Windows off, your hardware could be permanently fucked and set up to spy on you.

How are you supposed to install Gahnoo/Linux on laptops then?

Any operating system has access to the system, so it can do what it wants. In practice, you're not going to find a virus that installs from windows to a linux partition. It's just not financially worth it. I would say the bigger risk is something getting access to your UEFI software from inside windows, as privilege escalation if windows has always been so easy its a fucking joke.

>Using laptops at all
What do you mean how? Same way you install it on a desktop.

>Running Windows just once is enough to compromise it
They do it in the factory to test it. I hope this fact upsets you greatly.

Just run wine user. A little bit on tinkering (or buy the commercial version) and you can keep you money from Microsoft

>software can permanently fuck hardware

>what is bios/uefi/firmware

this
by 's reasoning, we should use no hardware at all

ReiserFS doesn't have this problem.

There's not good raisin to dual boot anymore with virtualization and such being cheap enough. A $10 wifi raspiss can handle anything you'd want to do on lignux

>Overclocking can brick a system
>systems can be overclocked by software
>therefor software can brick a system
QED

I mean computationally cheap. Windows as host, pretend to be 1337 h4x0r in virtual machine.

Just get wine on the linux partition. I'm using it right now, installing CS:GO

>he doesn't build his own laptops

A Windows VM will get you 95-99% of the performance that you'd get running games normally on Windows.

Do you have some credible sources/benchmarks/videos for such claims?

DuckDuckGo "gpu passthrough benchmarks".

There's no good reason to have lignutz as host when you're just dicking around as a skid

Compare "NPT Patch" with "Native".

WTF?

Alright, thanks Anons, I didn't believe it at first, but it seems believable. Will definitely take a deeper look about it.

Exactly. You can literally NEVER have the guarantee that every piece of PC hardware you own has never run Windows.

windows is a virus
so wipe it out and install gentoo
good luck

Take the red pill and be a girl then make three movies in a row that flop even though two of them are really good :3

>Can Windows somehow see and/or access what I do/have on the Linux partition?
Yes, in as much as you can trivially mount a NTFS partition in Linux with the right software. Personally, I use NTFS-3g to do exactly this, so I can share files between the two operating systems easily.

Is this a security risk? No, not at all. Unless Windows or Linux have some particularly nasty functionality that are, as of yet, unknown. Taking this train of thought further is approaching the tinfoil retard zone.

Is this a privacy risk? Almost certainly. I have no doubt whatsoever that Windows "telemetry" is keeping note of whatever it possibly can, whether or not it happens to be on an NTFS drive.

TAKE THE VARGPILL

How is this not a security risk? I understand that it can have some practical use, but if your Windows partition gets somehow attacked, the attacker can access files on the Linux partition as easily as you can.

>Is this a security risk?
It is. You're just stupid.

>How is this not a security risk?
It is. He's just stupid.

Windows is such an affront to freedom that I could not be party to its under any circumstances whatsoever.

Good job, Sup Forums.

>>try to run gayms in vm, it sucks dicks
But it doesn't though.

This is why you put your lignux toy in a VM and not need to shut down all your stuff every time you want to access it.

To help you along, you're going to want to look into these subjects, in order:
1. KVM.
2. VFIO (GPU passthrough).
3. Optional: KVMFR (Looking Glass).
Check the Arch wiki, the /r/vfio subreddit, and Level1Techs.

I want to play games in my windows 10, but I want to give a try to linux for noobies..
But I dont know how to do it, is there any tutorial video to follow?

get VM software, get iso for licknuts bistro you want, make VM and install to it

You'll never learn how to learn about this stuff if you continue to rely on spoonfeeding. Are you female or just neurotypical?

What the fuck is VM and why there is no video tutorial teaching this shit?

Thanks again user.

VM := Virtual Machine.
To put it simply, although probably not accurately, a VM is a software abstraction of computer hardware that enables you to run a whole operating system on top of it. In practice, you could "run" an imaginary PC with Windows or Gahnoo/Linux simply by clicking on a desktop shortcut, just like running a program.
Getting one up and running is much easier than it seems, get some VM software like VirtualBox or VMWare, an ISO of your desired system and you're good to go. All steps are guided, you can't go wrong.

Dual booting kind of old school. Ever consider another machine or VM In one?

Sometimes you want the absolute best performance you can get on both systems.
Virtualization has greatly improved over the years, but it still can't beat running on the bare metal.

Cool I understood
This doble boot will not make shit in my windows and it will start to work bad in the future?
If i want to install notepad++ and code I do it in linux and use windows to playvidrogames?
Watch porn in linux orbwindows?

Lol I read my comment and lol
