Windows 10: BIOS can't find Windows 11 boot option after wiping another disk.

I boot into the Windows 10 to create a backup Create system image and put it in another disk HDD on my computer.

Wiped Hard Drive Can't Boot Vista

I did try every possible boot order and even with deactivated options, which I don't even know how or if that is helpful. I will try the Vista possibilities. The OS was listed in the BIOS, whatever that means, and it said it was a factory version, which I think is a good thing.

The PXE error messages may have occurred when I activated the network adapter and tried that in the boot order. Obviously, I am in way over my head. Thanks for the suggestions!

 

How does Windows boot to advanced recovery option e.g. command prompt?

- that gives me a 454 'Unexpected error' This tells me that the BCD is partially corrupted.

The commands: shutdown.exe /r /o /f /t 00
or: %SystemRoot%\System32\Cmd.exe /c reagentc /boottore&shutdown /r /f /t 00
should boot into Recovery if everything is configured correctly.
FYI, If Windows is configured correctly:

1. If Reagentc is disabled, you still can get into Recovery but with limited options.
2. If Reagentc is enabled, you'll get all options.
3. If you boot Windows using Recovery USB stick, You'll get into Recovery with couple of options missing.

Here's my suggestion if you want to try:
OPTION 1: Will save the trouble of re-install Windows.

1. Download the image of my first 3 partitions (450MB Recovery, 100 MB EFI partition, and 16MB unformatted primary)
   EFI_Boot-00-00.7z - Google Drive
2. Run Macrium and restore the image from step 1, overwriting your existing 1st three partitions, leaving C alone.
3. Delete the 490MB Recovery partition.
4. From Macrium, run fix boot problems.
5. Reboot. Open Admin command prompt then run Reagentc /info to make sure that it is enabled. If not, enable it.
   if failed to enable, reboot and try again.

OPTION 2: Assuming you've already had Windows backup with Macrium.

1. Wipe out the first 5 parttiions. (450MB, 100MB, 16MB, C Drive, 480MB)
2. Fresh install Windows 10
3. Restore C drive from backup image, run fix boot problems
4. repeat step 5 from OPTION 1 above.

 

Windows 10 Reset (remove files, no disk wipe) fails with Inaccessible Boot Device; Defender Offline fails with 0x8007002

Two identical Dell Inspiron 660 systems (one for each child):

• Win7 --> Win 10 upgrades went uneventfully, normal function afterward.
• 1st system then put through Windows 10 Reset procedure with file removal AND disk wipe, completed successfully, normal function
• 2nd system then put through Windows 10 Reset procedure with file removal WITHOUT disk wipe --> procedure fails:
  • INACCESSIBLE BOOT DEVICE error is thrown, with an endless reboot cycle
• Based on
  this thread reference to
  KB2673509, Windows Defender Offline downloaded and run to create USB installation
• USB device inserted into affected system
• Boot device sequence manually directed to USB during reboot cycle via BIOS <F12> key function
• Windows Defender Offline initiates, but halts throwing error 0x8007002

• This code
  appears to be related to a problem with Windows update, which I can not rationalize given that this is explicitly an
  offline tool.

What are the suggestions for next step(s)?
