DISKPART accidentally made my disk non bootable, but files still there

I somehow changed my hard drive type to “basic data” and now I’m stuck at Windows recovery screen.

Nothing works in recovery screen, only command prompt, startup repair doesn’t work and system restore says I need to select Operating system first, seems like doesn’t recognize the operating system.

As i searched online for solution came out with some “bcdedit” like i would need to recreate boot again?

I’m on another hard drive now and can see files in that disk and copy most of them, but i would like the disk working back again without losing any data, i will include photo here if will be possible.

I run Windows 10 64bit on Windows 11 PC build, but was working until i did that with diskpart…

I also tried with CSM and SMT disabled/enabled in bios, various boot priorities, nothing works.

I’m hoping of getting some experienced help here.

Volume J: on problematic disk is empty. I’m now on another disk in this computer and works normally.

I tried a lot, i think i only need to change disk type back to bootable or something to do with the boot… I tried with Windows usb install media but still doesn’t work…

Ok so tried those bcdboot commands and still doesn’t work, anyone had similar problem and fixed it?
