Windows failed to start. A recent hardware or software chanve

I uninstalled Ubuntu by deleting the drive allotted for it from windows Disk Management. But I guess I didn’t delete the grub. I have tried several videos. But none of them works for me. Because the BCD file of mine is “file: \BCD” (not file: \boot\BCD) Error code: 0xc0000098 Now I get Ubuntu and windows option when I press F9 at starting but choosing windows will will give the above error message and choosing ubuntu will take me to grub command window. Please help me with this.
