Thank You Soo Much…..U saved me
Why does it say: failure when attempting to copy boot files?
Someone please help…
I cannot thank you enough! This worked like a charm… Very clearly explained and to the point. Absolutely amazing! The only additional thing for me was that while formatting i.e. after…
format S: /FS=FAT32
It asked me to enter the current volume label, which was… SYSTEM
After that it went just like the vid.
The issue I was facing was that my system wouldn't recognize windows and would only show me the blue screen with troubleshoot and shutdown options. I must've watched like 10 videos and visited 10 more forum pages, nothing helped. You sir, are a blessing. Thanks again!
Ohh! Thankyouthankyou! I hooked up my old windows drive to my computer and it messed up the uefi. apparently windows 10 and uefi doesn't like two separate windows installations on the same machine… 😀 Lesson learned. 🙂
Oh, man thanks a lot, a sucked for 2 days and your way was the solution for successfuly enter my Windows
should I write legacy if i am using legacy mode??
The description needs to be fixed. It says fs=fat32, but it should be fs:fat32
Hero!!!!
Thank you so much! I increased the partition windows lives on not realising this would invalidate the EFI. You saved the day!
When i do the format it hust says the fike systen is FAT32
Enter current volume for drive S:
Nvm its fine now thanks
This is the only fucking working tutorial out there.
Holyyyy F*ck man!! Thank you so very much. My dumb a** formatted EFI partition while installing fedora. I thought I had lost my windows. I watched so many videos how to fix it. This was the one that worked (and was simple to understand).
You doing God's work
Thank you
I literally don't have enough words to tell you how thankful I'm with you, you are the best. Literalmente no tengo palabras suficientes para decirle lo agradecido que estoy con usted.
Absolute legend! There is quite a bit of documentation out there on doing this, but almost all of them you run into permission issues, even when doing it from a recovery disk in CMD. This worked a charm! My entire EFI folder was missing, so I had to shrink the main windows partition by 200MB then made a 100MB partition from that for the EFI, then basically followed your guide. Thank you man.
Why don't the format work on me?
You're a genius… You just saved me, I've watched many tutorials but zero only yours solved my problem… Much thanks and God bless you 🙏
Doesn’t work. When I select the usb stick to boot from, my PC sends me immediately back to „select disk to boot from“.
I can't do it because next to disk 0, it says 0 B, 0 B. It said that there's are no partitions on this disk to show… What does that mean? But under it where it say disk 1, it has 57 GB, 25 GB
Hi, it did not work for me and when I formatted 500mb system partition and copied files as you described, my computer is even in the worse state, now I can see only the screen "your pc couldn't start properly" without recovery options. How can I reset Windows with keeping personal files? 🙁
Thank you, this is the best tutorial to fix EFI, I cloned a HDD into a SDD using a GPT partition table and was having trouble to make it boot, and by following your tutorial, I was able to make it work in the first try. Thanks 😀
sir, after following this tutorial, windows is booting perfectly but in recovery environment "factory image restore" and all other options are missing. Also, I am getting error 0x80070020 during the windows update. please help me in solving these issues.
thanks.
Big thank you, in my case EFI partition was deleted, had to create and then follow these steps. My System is happily back now 🙂
Good tutorial, man. Unfortunately, efi wasn't the cause of problem, it seems.
Bro YOU SAVED ME!!! I owe you a big time
Spot on !!!!
Hey man, I get this error when trying to copy( bfsvc error: unable to load mui file for bcd strings (2) )
I cannot format my system drive. It says "Cannot format. This volume is write protected." What to do??
Thank you so much. This saved my laptop when the Windows partition didn't boot
👌 Thanks
Thank you!
You are the BOSS!
What if I have an another system as Ubuntu on EFI partition? I don't want to delete it
Fantastic tutorial ! Even was able to reinstall bootloader from recovery partition. Thanks a lot for your job !!!
