I recently encountered a problem with my PC where the screen suddenly went black. Upon rebooting, I received a message instructing me to insert a boot device. The BIOS can't detect my SSD, which leads me to believe that the EFI might have gotten corrupted. I attempted to use Windows Diskpart to delete and recreate the EFI, but it wouldn't let me because it said the drive was read-only. I also tried using a system rescue tool, but it said there was no data available on the SSD. I'm really hoping to avoid buying a new SSD if possible. Is there any way to fix this, or is my SSD completely bricked?

It's worth checking something else first, like the CMOS battery. That went bad for me once, and replacing it for just a few bucks solved my boot issue. Give it a shot!
Just to clarify, when you say the BIOS isn't booting from the SSD, can you access the BIOS at all? If you can’t access it, the SSD isn't the issue. Consider checking the RAM. Reseating or trying different slots can sometimes help troubleshoot.
You could try doing a complete re-install to see if it helps. It might fail, but at least you'd know for sure if the SSD is dead or not.
That same situation happened to me recently. I opted to get a new SSD, and I'm hoping to move my files over from the old one since I can still access them in the EZ Flash.
If your SSD has gone into read-only mode, that’s usually a sign it’s toast. It happens when the SSD detects critical issues. Try booting from a rescue USB and checking the S.M.A.R.T. health states of the drive. You might be able to recover some files, but the drive itself might not be salvaged.
Drives can and do fail, so backups are essential. If it's still under warranty, consider an RMA. If not, unfortunately, you might need to get a new SSD.

I faced a similar issue and managed to image my faulty SSD to a new one without losing data. It also let me upgrade to a larger capacity!
