data recovery after filesystem change ntfs->ext4

so here's my story:

i wanted to instal arch on a friend's machine and it was a success. BUT i accidentaly used a wrong partition and changed the filesystem from ntfs to ext4.
normally i would use something to recover my data but the filesystem change bothers me.
is it even possible to recover anything from it?

i have heard that test disk would be able to do this task, but there's a probability of damaging other partitions.

what do i do?

any help is appreciated

What exactly did you do? As far as I know, there is no way to 'change filesystems'.
Did you run a mkfs.ext4 on said partition?

It sounds like it was formatted, but even so it may be possible to recover some data. If it is only the partition table that was fouled the it may be easier. Either way I would recommend System Rescue CD in particular as you mentioned testdisk and photorec.

the partition has beed formated from ntfs to ext4 while instalation. so it has arch on it at the moment

As tesjo said, testdisk and photorec are the tools you are looking for.

Check PhotoRec wiki, and the step-by-step guide in it.-
