Windows 10: Windows 10 doesn't have boot option

Today I tried to install Ubuntu through USB and after turning off my windows 10 I clicked multiple times F12 button for opening the boot options and it did. But the problem is there is no any option for choosing the boot option. Please help me.

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

Thanks for your answer, ken!

I deleted all my data. I had have it backed up.

I did a clean installation using the windows media creation tool (usb option).

No, I didn`t. I thought a clean installation would solve the problem.

After posting my previous message, I did it.





After chkdsk, I close cmd and tried to boot and the laptop just turned it off. This morning I`ve restarted it and automatically windows did a repair. Windows has booted and it seems that the repair tool has removed chrome and acrobat pdf reader (the only two programs I had installed after reinstalling windows).

Now Windows is installing updates and restarting my lapop, I`m kind of frightened. I don`t want it to happen again. Anyhow, I want to know what has brought the issue

I`ve been looking for information about the error code at the end of the picture and I didn`t get anywhere.

 

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.
