Whatever you decide, make sure you've got a backup of any important data before you start making any partition changes. Things go wrong occasionally even when they shouldn't.

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.

Depends on how the partitions are arranged. I'm assuming your Windows is first (going left to right), then probably your boot partition, then your main ext4, and then maybe a swap?
Definitely shrink the windows partition using disk management, but then in Linux you can clone your boot partition to the beginning of the free space, delete the old boot, and then expand the ext4. You don't HAVE to do it from a live environment, but it is the safest.
I didn't google much, but this seems about right: https://www.baeldung.com/linux/resize-partitions
IMO your first plan is best given your setup. Personally I keep Windows in a VM, that way it's entirely controlled and I don't need to reboot.
I see, thanks. I'd love to use Win in a VM but I doubt it's as flawless as on metal. For example, would WebSerial API work as well? Idk, maybe.
Unless you have a dedicated GPU just for the VM(s) it isn't awesome for anything graphical, other than that it works for most things.
I don't think you can shrink an active partition, especially if you're booted from it. Just use gparted live, it's fine. I prefer doing all my resizes offline. The only thing I do online is extending.
I thought so too, but apparently you can. I saw people on youtube do it on their active C partition
Had to do this on Win11, it worked.
I shrunk my Win10 partition from within Windows to make space to dual boot into linux so you definitely can shrink an active partition.
@dysprosium @catloaf GParted takes a lot of time doing tasks. Is this normal?
depends heavily on amount of data and cpu speed. I wouldn't wanna interrupt though
And hdd/ssd speed. Honestly it's more about the drive speed than the cpu.
Yup. If data has to be moved, that's one read and one write, in different parts of the disk. That's going to be slow. (At least they'd be sequential, I think.)
Depends on the task and the hardware. Disk operations can be anywhere between instant and hours.
In some cases, days. When I last retired some drives in my NAS, the task of moving the partitions onto new drives was a 48 hour process.
Like already said, unless you're sure something has gone wrong, don't interrupt. As long as it's still doing its thing, it'll get there.
You will be fine doing your first plan. Defragment your windows drive first (you’re not wearing down your ssd with that operation. Modern ssds have wear leveling tech and are good for like 100k writes so it’s not a big deal to defragment it. Also if it’s getting slower doing a level uhh 2 spinrite scan will fix that by rewriting everything. Ask if you want to know why).
Oh, Gibson finally stopped mucking around with his certainly DOA SQRL project long enough to get Spinrite working on modern systems?
No it’s still only x86 lol.
I’m almost 100% you can get the equivalent of a lvl2 spinrite scan out of badblocks but haven’t tried it yet.
Drat. 6.1 was supposed to add UEFI support. It's kind of useless without that.
I’ve only been able to boot it through “csm” or equivalent methods on uefi systems. Got a stack of slow as molasses soldered storage laptops here that could use it.
Maybe soon I’ll try to replicate it with badblocks. Better buy a bunch of old m1 mbas if it works.
So I finally did it. Results?
First was unable to shrink in windows due to a bunch of reasons, but I overcame them: hibernation file, page(r)file, and other bullcrap.
Finally, I could shrink. Then, a fatal error in the shrinking process. I ignored it. Waited few minutes and the disk seemed to have shrunk after all. Weird.
Then proceeded as planned. GParted the rest. All is working fine now!
Moral of the story? None.
some of file system not support extend from the beginning of the partition. make sure you checked ext4 support it
I'm not sure whether this is equivalent, but the free space was on the left of the root partition, so I first moved the root partition to the left of the free space, then extended it to the right. It probably took twice as long. And maybe the risk is the same, I've no idea
