How to switch to other OS without needing to shut down my Linux

So I m running a MSI GF63 laptop, I have a dual boot installed with Windows 11 on other partition . Sometimes when i open my lid after a long period of time (usually first time in the morning), I was using windows before but it boots from the start, meaning I see the boot menu, I can successfully boot into garuda too, can't use the wifi, everything else works. And when i decide to restart the system from linux and then boot into windows, all my stuff from last night is still there.

What i want is to achieve this in linux, meaning a button or command of sorts that will save my current state (in linux), and allow me to reach my boot menu so I can boot into windows (to play some games maybe) without losing all the windows and stuff i had opened on different screens. And when I log off windows, I can just resume the work that I left in linux.

That describes Hibernation. If this isn't in Garuda settings/welcome, look at Archwiki for instructions to enable it properly.
Although it should work fine and not interfere with Windows AFAIK, I have never used it this way. Maybe some other user can add such an experience :person_shrugging:

i thought so too, so i looked into it on arch wiki "Power management/Suspend and hibernate - ArchWiki" but i don't think it will give me a button. Please correct me if i m wrong or if anyone has better documentation.

If you enable/configure Hibernation properly, your DE (Plasma) should show a nice button and some configuration options.

I'll give it a try and get back to you, is there any thing i should avoid or skip?

quick question, can i use my zram partition as swap file?

i tried to do this but i couldn't. I also created a swap partition using kde partition manager but i cant find it in lsbdk (it just comes blank)
i was trying to follow this guide "Arch Linux + Grub | Setup Hibernation - YouTube" but couldn't due to lsbdk, also should i follow this guide because on the arch wiki, i read that btrfs has a different procedure than other file types.

So essentially what you looking at doing is sleeping your linux state to a swap file. I am going to call this out and say its possible but difficult. Also from personal experience hibernation works best if you going to boot straight into the same OS straight away but changing OSs could be interesting.

Systemd, Btrfs and Hibernation can be tricky to get right.

Some links i suggest reading

Garuda installer can do this automatically, if selected during installation (there is a combo box setting related to swap/hibernation)

That's very much true!
That's why Garuda has included this in the (initial) installation, to make it easy.
BTRFS has special requirements concerning swap.
All info is at Archwiki.


so should i maybe give reinstalling garuda a try?
or can i get this without wiping off all my data?

The best way to switch to other OS without shut down is to have one OS on each computer or put up with a 30 second shut down and a 30 second restart.
Problem solved, that was easy. :sweat:

The east way is to reinstall, backing up your current data, if possible for your needs.
Of course it is possible without reinstalling, but complicated and I can't help you with this. Maybe someone else could walk you through with the procedure :person_shrugging:


I have not tried this yet, but the Logitech unifying receiver allows me to switch mouse & keyboard between active computers when a certain button is 'clicked.' Ergo, I only need one mouse & keyboard but two receivers, one being the master.

But it requires Logitech's software, receiver(s) and AFAIK these "advanced" features aren't usually available via the limited Linux/AUR software support. I don't use them in either OS.

Another option to explore is to setup KVM/QEMU emulation and install Windows with GPU passthrough -- which can be a challenge to setup.

Since you're using a dual-graphics (Optimus) laptop, you can use my guide for help

BUT... this solution requires shutting down the session. Unless you're fine with not having the NVidia GPU in Linux. Perhaps you can find a work-around or compromise that suits your needs?

From the Arch Wiki:

Warning: Data loss can occur if Windows hibernates and you dual boot into another OS and make changes to files on a filesystem (such as NTFS) that can be read and written to by Windows and Linux, and that has been mounted by Windows [3]. Similarly, data loss can occur if Linux hibernates, and you dual boot into another OS etc. Windows may hibernate even when you press shutdown, see section


Since hybernation and using the mounted drive from a different OS won't work...

With my KVM/QEMU setup, I can boot into Windows a near-native performance without losing anything BUT without GPU passthrough, which is fine for most tasks except gaming.

Or, I can boot into Windows with GPU passthrough but that requires killing the session (unless you don't need the GPU in Linux at all). Games at near-native performance; sometimes it even feels smoother than native.

I got 2 KVM boot setups pointing to the same storage, so I decide whether I'll kill session and pass the GPU or not each time.

I don't think you'll find a much better option than this, but it does take a while to setup. Took me a full week of debugging.

How about this, in System Settings - Workspace - Startup and Shutdown - When logging in, chose Restore manually saved session. It will restore the applications you haven't turn off when you leave.


This is the closest solution to my situation which can be implemented without much hassle. Thanks
