I have dual boot Win10 and Linux (manjaro), and I want to shrink my NTFS C:\ partition to free up space in my ext4 root partition on the same physical drive.
I keep reading online that NTFS partitioning is best handled by Windows itself. However, Windows cannot partition ext4, so I thought I’d use a live GParted session for the ext4 extending part only.
So why not shrink my C:\ partition IN WINDOWS, obtain my unallocated space, then boot into live GParted, and use the unallocated space to extend my ext4 root.
This, or do everything from GParted in one go? What has the best chance of success?
I could also install GParted on my running Linux distro, and do the extending from there. But I feel like GParted live would somehow be… better?
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.
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.
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®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
