No bootable drives showing while installation of windows;

I have a windows laptop which had windows eleven.

I was using it today and for some reason all of my apps stopped responding and then my pc shut down. When it tried to turn it on; it showed a message : No bootable device found.

I figured out my OS drive got corrupted;
So I decided to clear it and again install a new os instead ; so using a bootable windows 11 drive, i tried installation but I cannot find my drive in the “select your
installation drive” menu!!!! I had two drives in my laptop one corrupted and the other uncorrupted and BOTH ARE MISSING!!.

Now this is a very emergency situation for me. Can anyone tell how can I make the computer accept my drives or how to install the OS on the pen drive itself??

I have a Very Very important presentation Tommorow..
