I was editing my disk and when i wrote the changes and exited cfdisk, no cli command worked. Thats when i realized that im f-ed up.
So is it possible to recover my machine now?

Live boot and, if possible back up everything first. Everything as in the whole disk. So ``` dd if=/dev/nvme0n1 of=backup-disk
I dont think doing back up is possible. Coz i shrinked a 100g partition into 32g which had 84g of data. Is it possible?
What they’re suggesting is to back up the whole disk, rather than any single partition. Anything you do to the partition to try and recover it has the potential to make a rescuable situation hopeless. If you have a copy of the exact state of every single bit on the drive, then you can try and fix it safe in the knowledge that you can always get back to exactly where you are now if you make it worse
Also, it’s probably possible to fix the partition so that it’s as big as it used to be. It’s likely that some of your data is corrupted already, but the repartitioning won’t have erased the old data except here or there where it’s written things like new file tables in space it now considers unused
Yes a back up is possible. Don’t back up partitions, back up the whole device. All 150+g at once.
Whenever you try to mount the device or the filesystems, make sure to mount it read-only so that no changes are written to the device.
Also, shrinking 84g of data into 32g is definitely not possible. Just changing the fdisk partition table doesn’t shrink or relocate the data. You need a filesystem-aware resizing tool to shrink the filesystem before shrinking the partition.
Hopefully you can just change the partition table back to the original values and get a clean fsck.
clonezilla?
does that still exist?
