From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

New to linux, would like some help setting up dual boot. (self.linux)

Got an old laptop from a friend I'd like to rejuvenate, the plan is to set up a light distro so it wouldn't be as slow as it is right now with windows 10.

Now, I'm aware windows updates can fuck up a dual boot system, so i have a few questions about how to minimize the threat of that happening.

What i think of doing is running a few scans to check the disk, then setting up Linux Mint, because it is beginner friendly, and (relatively) light weight.

What I'd need help with is trusted guides and also tips for setting up dual booting, I'm sure I'll need to do disk partitioning and I've done that before but I'd still want to make sure I'm doing it correctly.

Any help would be welcome.

Make sure to disable Windows hybrid sleep. If your system isn't shutdown properly and you access the Windows partition from another system that can destroy data.

If you just want to keep the data on the Windows partition and usually don't need to run Windows, I'd remove the Windows drive and keep it somewhere safe, and get another SSD for Linux. That way, the two systems are completely separate and can do nothing to each other.

Swap is mostly a crutch for too little RAM, if the system doesn't have enough the best solution would be an upgrade. If that's not possible, consider zram-swap, or if you have to, swap to an SSD (that will reduce its lifespan, though maybe not in a relevant manner). If you swap to an old HDD you won't have much fun using the system.

Hybrid sleep was luckily already disabled, and the laptop has 8GB ram so it should be fine.

The Linux mint installer has an option built-in to create a dualboot. Just follow their guide and be sure to select “install alongside windows 10” at step 5.

[–] BlackRoseAmongThorns 2 points 14 minutes ago

Following the guide as i write this :)

You probably know most of it so just some advice: Don't format the Partition table (MBR to GPT etc.) on the disk whose data you wish to keep.

Shrinking a partition or moving it carries a small risk of data loss and will take significantly longer than creating a new partition (since data needs to be cut and pasted from one area of the disk to another). If your old laptop has an empty slot for another SSD or NVME drive you can plug that in, and still dualboot and having the new drive Linux only.

Also to deal with the occasional Windows cockups, just carry a boot-repair USB, the auto repair has fixed the Windows issue for me 90% of the time (the other times are usually boot order priority or other BIOS setting)

I did that once and it wasn't a nice experience. Windows will always find ways to screw things up and you'll constantly be dealing with their shitfuckery. Outside of gaming there aren't really many reasons to stick with Windows and even gaming works great except on titles where it is explicitly sabotaged by the publishers. If you're dealing with an older laptop, this likely isn't a consideration anyway. If you're unsure whether Linux is for you, my advice would be to install it in a VM first and see if it works for you. Chances are, you won't miss Windows at all.

[–] r00ty@kbin.life 2 points 2 hours ago

These days with UEFI it's much less likely to break things. Worse case though you just boot from a LIVE USB boot, chroot in and rerun grub/your bootloader installer. Often even if windows puts its own bootloader first, you can choose your bootloader from the bios boot menu and just rerun the bootloader installer.

It used to be a lot worse.

[–] BlackRoseAmongThorns 2 points 2 hours ago

Windows is the old OS i have a reason to keep, otherwise it would be all linux.

[–] daisyKutter@lemmy.ml 3 points 2 hours ago (1 children)

A couple of days ago I setted up my pc with dual boot; I recommend to install Windows first and then install the distro you want with a swap partition of at least 16Gb and on the linux install options choose GRUB as bootloader

[–] BlackRoseAmongThorns 3 points 2 hours ago (2 children)

Thanks, a few questions, what is a swap partition, and why is it needed?

Also i have a ton of free storage so the linux install will probably have over 200gb in its partition

[–] neanderthal@lemmy.world 3 points 2 hours ago

A swap partition is akin to the page file on Windows. The kernel will use it to move memory pages it doesn't anticipate using in the near future to it so it can use that RAM for other things. It will also use it in a pinch when there isn't enough RAM on the system. It isn't strictly necessary, but it can prevent programs from crashing at a huge performance penalty. It is necessary if you want to use sleep or hibernate or whatever it's called when it is powered off physically but resumes what you were doing instead of booting when you power it back on. That takes as much swap as you have RAM at minimum. If you want that, a good rule of thumb is 1.5 times physical RAM.

I have servers I administer for my job that have over 100GB of RAM with very little swap, like 4GB. The applications and machine are tuned and sized so the physical RAM is at ~85% and swap is barely used. The swap is mainly for non application stuff like IDS agent, backup agent, monitoring agent, etc.

If swap becomes a problem, you can adjust the kernel vm.swappiness parameter as needed. It might take some trial and error to get it right.

@BlackRoseAmongThorns @daisyKutter Swap is a place on disk that gets used as a slow, temporary place to put memory when your RAM is full. Windows uses a swap file on an existing partition, while Linux generally uses a dedicated partition instead (although you can use a swap file if you really want to).

Appropriate sizes for the swap partition are hotly debated. Twice the size of your RAM if you have a small amount, or the same size as your RAM if you have lots is a good approximation.

I haven’t done this recently enough to guide you on the details, but step zero is to decide whether you are certain you want to dual boot or not. It adds a lot of complexity and brittleness that is best avoided if at all possible.

  • Try to find Linux compatible replacements for the software you need.
  • if that doesn’t exist, see if you can run it on Linux with wine.
  • If that isn’t possible, consider running windows inside a virtual machine on Linux.
  • If you do want honest, bare-metal windows then using two different physical drives will be easier and more reliable. Ideally your laptop has room for two drives, otherwise you can dangle a USB SSD (not a flash drive). Windows won’t install to a USB drive but Linux doesn’t care.

Yeah for anything except some games, wine/lutris or a virtual machine will work wonders. Not having to reboot is much nicer. You can also consider booting windows off a fast usb stick or usb ssd.

[–] Droggelbecher@lemmy.world 3 points 2 hours ago (1 children)

For me personally, having to reboot is part of why I like my dual boot. I have adhd, so it's good to keep gaming entirely separate from anything productive.

[–] unexposedhazard@discuss.tchncs.de 2 points 2 hours ago (1 children)

Thats a good point tbh. Nice brain hack

[–] Droggelbecher@lemmy.world 2 points 22 minutes ago

Now if only it kept me away from the Wikipedia rabbit hole haha

[–] BlackRoseAmongThorns 1 points 2 hours ago (1 children)

I'm going to use it for software development as im studying software engineering in uni, so probably not much else, and windows is the old OS of said device, so i just need to limit the windows partition and make a new linux one

[–] traches@sh.itjust.works 1 points 1 hour ago

Your best option by far is to overwrite windows completely. For most software development Linux is way better anyway.

[–] fredbrooker@witter.cz -3 points 2 hours ago (1 children)

@BlackRoseAmongThorns why? 🤔 😂 fuck dual boot, boot directly into Linux

[–] BlackRoseAmongThorns 2 points 2 hours ago (4 children)

Kinda need the old OS, it's a close friend's computer and it took too long to get just a few files out of it, i want to keep the rest just in case we missed something.

(Also I don't want to just backup the whole ass hard drive)

[–] MyNameIsRichard@lemmy.ml 5 points 2 hours ago

You're messing with partitions which means there is the potential for data loss, be it hardware, human error, or a random cat. You should, if the data is important to you, have a backup.

[–] XTL@sopuli.xyz 2 points 2 hours ago* (last edited 2 hours ago)

I'd get a new drive. Install a sane os and need tool and use that. They should be cheap these days. Put the old one in a safe place in case you need something from it. When you find it years on and notice that there was nothing important there after all, recycle it. That's a much safer approach.

[–] neanderthal@lemmy.world 1 points 2 hours ago

You could leave the Windows installation and not dual boot. Linux can read NTFS volumes. You will probably have to install ntfsprogs or whatever it's called.

[–] fredbrooker@witter.cz 1 points 2 hours ago

@BlackRoseAmongThorns that would be a good option, dd old drive, mount it when needed from cloud
