Windows 10: Deleted recovery how to get back or fix

I accidentally deleted my recovery partition my main disk is in bitlocker. I can't figure out how to fix windows without formating and I'm here begging to see if there is a way to recover or fix my drive. I have my bitlocker key. I have accessed it on ubuntu and can transfer it to the cloud and start from scratch I was just hoping I could figure out how to fix it before I did that

:)

 

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.

 

How To: Create recovery partition.

Troubleshooting Guide​

1. Q: So you have broken your boot loader and need to know how to boot into windows?

A: If you are reading this you are probably looking at a black screen with alot of white letters and a stop code saying a file is missing. Good news no need to panic.

• The issue is that easyBCD has probably deleted your boot loader or you were experimenting and F**d up.
• To get this back I'm going to assume you made the recovery partition exactly how it was done in movie
• To fix your PC restart the computer and enter your boot menu (usually F10-F12 depending on pc) select the physical harddrive the recovery partition is on.
• You should now start booting the windows 7 installer. when you arrive at the main menu in the bottom left hand corner click "repair your computer" It will automatically scan and attempt to fix your problem. It should auto detect that the boot drive location is wrong.
• Simply agree with the prompt and press "fix/restart" not cancel. At your next boot you should be happily at your desktop.
• Now open easyBCD and fix the menu so it looks like the videos, or try your experiment again.

Faqs​

• easyBCD (used for modifying the windows 7 and other windows OSs bootloader): Link
• camstudio (free open source desktop recorder): CamStudio - Free Screen Recording Software
• This method can be used with any OS.
• easyBCD has a hard time loading some ISO images on some machines. You may need to change how the ISO is handled or try a different method. Linux Distributions suffer from this the most.

Note: I have broken my system on purpose in multiple ways at your expense to teach you how to repair issues that may arise.​

 

Will deleting the factory partition render the recovery disk useless?

More than likely it is of no use NOW . The recovery disk is nothing more than drivers and some BS . You will not get the OS and recovering from a recovery disk only works if the drive partition is fine and has been untouched by any one .
The best thing to do is delete all the partitions and just install windows on the HDD make your own recovery disk and your done not to mention you get all that drive space back .
