So - recently my system has been having problems where it will reboot straight to the BIOS (UEFI Bios, latest version 1903). When it does this and I look at the boot menu (in EZ mode) and it says "The system cannot find any bootable devices". I used to be able to pull the power off the PC, wait a bit, then it would boot into windows. That booting process would take anywhere from 7-15 minutes even though I have an SSD. Now, however, it is maybe booting to windows every 20th time or so.. There are not a lot of boot messages, so I'm not sure what is going on.

CMS is enabled and all are set to UEFI only. The disk is UEFI boot, I'm sure. Mainly because that is how I had the settings set and it boots fine on occasion. Below is a link to imgur where I have the BIOS images and the post messages from boot

Still working on it :) I wanted to clone the disk so that I didn't make a mistake first. Now I am downloading the Windows 11 ISO. I'm running the original disk through DiskGenius now to see if there are bad sectors. Then, I suppose I'll put the drive back onto the old system and try to run the ISO and repair the MBR. That is my plan anyway. DiskGenius is already an hour into it's verification and it hasn't gotten very far :(

I am now responding on the PC in question after it was successfully recovered. It was a bit of a long process and I went through couple of iterations to be safe. Here is what I did:

  1. Cloned the drive initially with Easus.
  2. Used Windows Media Creation Tool to create a Windows 11 boot disk
  3. Went into Troubleshooting > Command prompt
    1. Ran bootrec /fixmbr (worked)
    2. Ran bootrec /fixboot (got access is denied)
      1. Ran diskpart and set up the UEFI volume as a drive letter (select volume > assign letter, I assigned it to N:
      2. exit diskpart and run: bcdboot c:\windows /s /N: /f UEFI
After this, I just started Windows up normally! Now I am going to have to figure out a good way to back this up properly, I think. I'm sure the old SSD was failing, it did have some bad sectors when I ran it through DiskGenius - so I suspect this was the real issue.
