Windows 10: Windows 10 doesn't boot after selecting original boot option in advance boot options

My PC was running normal but then after I selected the original boot option in the advanced boot options then it requested me to restart my PC after which it is unable to boot and goes on in a loop of automatic repairs I have tried troubleshooting but that doesn't work , I also tried to enter the safe mode but i doesn't restart to that point where I could select it so how could I get back into my PC without resetting it . Please help !!

Asus Uefi bios has no boot options?

three failed boots should bring up the boot options from Windows. This isn't a board thing; it's Windows.

you can also select boot menu to pop up on next boot from within the OS.

 

UEFI boot options disappeared from BIOS; now getting reboot and select proper boot device

In short, I need to get the system/BIOS to allow UEFI booting of the SSD.

Computer started up today with default BIOS settings.

• Only SSD 1(Windows boot) and SSD 2 were listed in BIOS; HDD 1 and HDD 2 were not visible
• System would not boot. Gave the 'reboot and select proper boot device' message
• Boot menu has no UEFI/EFI (or Windows Boot Manager) entries anymore

I went into Partition Magic/Gparted and confirmed :

• All drives are still showing
• All drives' data is in tact [EFI volume/partition is still listed (and can be browsed/files accessible)]

Gparted print out (note dev/sda2 apparently that is normal behavior) :

/dev/sda1 (locked) EFI System Partition--Fat32--/media/sda1--100.00mb--46.81MiB--53.19MiB--boot,esp
/dev/sda2 (exclamation mark) Microsoft reserved partition--unknown file system--no mount point--128.00MiB--unused spaced--msftres
/dev/sda3 basic data partition--ntfs--/media/sda3--118.58GiB--70.78GiB--47.80GiB--msftdata
/dev/sda4--ntfs--/media/sda4--450.00MiB--327.71MiB--122.29MiB--hidden,diag



As I am able to boot Windows installation from USB, I tried the standard startup repair. It said it was not able to fix any problems.

Next I tried to repair the EFI with Diskpart in the shell:

• sel vol 1 (note that Diskpart states EFI partition is 'hidden')
• assign letter=z:
• cd /d z:\EFI\Microsoft\Boot\
• bootrec /fixboot
• bcdboot c:\Windows /l en-us /s vz /f ALL

It completed all tasks successfully. Unfortunately that did not work.

Other things I have tried :

• Removing CMOS battery and replacing with a new one - my HDD started showing up again after doing this.
• Using the old MBR commands(in hopes it would force the Windows startup repair to recognize and fix a problem)

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd​

• Loaded BIOS 'optimized'/defaults (the system did this already once before, hence why I am in this situation, though doing it manually seemed like an option worth trying. Note that after doing this and restarting the system, HDD's stopped showing again)
• Removed new CMOS battery and left it out of the system for thirty minutes
• Formatted EFI and msftres partitions, then rebuilt the EFI boot records

In summary, am looking to force the BIOS to see the EFI partition on the SSD boot drive, as it is not an option any longer.

 

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.
