Formatted Win 10's SSD now can't boot into Win 11's SSD

[Cyberspirit]

I messed up, I've had Windows 10 on one SSD and Windows 11 on another and I wanted to get rid of Windows 10, so I just nuked the SSD it was on in BIOS using MSI's Secure erase function.

 

This I guess also got rid of boot manager so now the drive that has Windows 11 cannot be booted into. I thought that it would just have its own but I guess not.

 

Is there any way I can boot into it or am I just screwed and have to reinstall everything?

What happens if you manually boot into your Win11 SSD trough a boot manager in the BIOS?

If you have a bootable windows 11 usb see if it lets you troubleshoot this issue. Otherwise, I had that happen to me once with W10 and I believe I used this guide here.

Doesn't show up at all so I cannot. I've installed Win 11 on the SSD Win 10 was but I still don't have an option to select my old Win 11 SSD.

You probably need to rebuild the ESP and MSR partition for it to work again

Seems like a pretty good guide but my drive didn't really want to cooperate so I ended up just nuking both and reinstalling Win 11. Lesson learned, I suppose.

 

Thanks for the help though!
