"after getting nowhere analyzing"
That is a pretty short useless test description!

Read here:
https://www.cgsecurity.org/wiki/TestDisk

The manual, the wiki everything is already there. In addition to that there is a forum where I repetively always give the same advice to the ever repeating same question.

right, sorry about that i have no idea what im doing right now
by getting nowhere i meant analyze - no partition found or selected for discovery - deep search - repeat and also this,
Invalid FAT boot sector
1 P FAT16 >32M 0 32 33 12748 21 9 204795904
1 P FAT16 >32M 0 32 33 12748 21 9 204795904
2 E extended LBA 12748 53 42 25496 139 51 204802048
No partition is bootable
after getting this error i tried advanced - boot - rebuild bs but still no luck

i've already read the test disk step by step section but i still don't know what to do...

i've read most of the threads and yes there already are answers to my problems but the thing is it seems i have multiple issues regrading the fixes itself

for example rebuilding bs didnt worked, and after deep search i have this issue

Disk \\.\PhysicalDrive1 - 500 GB / 465 GiB - CHS 60801 255 63
Partition Start End Size in sectors
1 * HPFS - NTFS 12748 86 11 25496 139 51 204800000
Boot sector
Status: Bad
Backup boot sector
Status: OK
Sectors are not identical.
A valid NTFS Boot sector must be present in order to access
any data; even if the partition is not bootable.

and i dnt even know what to search for unfortunately
