Hello
I'm New to Mac and apple products ,, i just bought a macbook air 13 inch 2014 and i tried to install windows 10 on it ..
No matter how any times i do the procedure of installation using bootcamp and setting all details,i always get this screen after i boot my mac to install windows 10 !
I used several iso files of windows but nothing changed ! i always get this error !
Can somebody help please !

This usually indicates BCD corruption. Can you check your EFI partition for any Microsoft-related files?
Thank you for replying 🙂
Honestly i didn't understand what you said,, how can i acces EFI partition ? when i reboot my PC i get 4 choices,, mac partition and recovery for mac partition and windows partition and EFI partition,
when i choose EFI partition it gives me the icone of windows and after 10 seconds it gives me the error screen ! the same thing happens with the windows partition 😟
The Mac's EFI partition can also contain your Windows Boot Manager. For example, see Re: Can't resize Macintosh HD partition . This will give you the steps to mount your Mac's EFI partition and look at the contents. Please do not modify any contents.
thank's but i don't see the point here !
i want to install windows 10 and it gives me the recovery error screen ! is that gonna fix my problem ,?
You have a partial installation which is why you see two additional selections, Windows and EFI Boot. Are you using Alt/Option key after the Mac reboots and before the installation for W10 shows?
yes i click on alt after the PC reboot,, but before that when i do the partition of windows using bootcamp the PC reboots automaticaly and it starts the installation of windows 10,, the windows icone shows for 10 seconds and then the recovery error screen shows !! thr same problems occurs when istalling windows 8.1 !
Do not use Alt/Option to interrupt the Reboot-Installation sequence. You will need to clean up the failed installation. Can you use BC Assistant to remove the partition and restore the Mac to a single partition and start the process again?
i did that operation about 8 times ! i remove the partition and i create a new one using bc assistant and it starts the installation of windows 10 automaticaly and oops the blue screen again ! 😟
Can you mount the EFI Partition using the link I posted earlier and post the directory of the EFI partition? There are two ways to fix it.
1. Mount EFI and delete the Microsoft and all sub-directories as mentioned in the link, or,
2. Backup OSX via Time Machine, boot into Internet Recovery, erase your internal disk and restore from the Time Machine back up.
i mounted the EFI :
here is the outcome :
MacBook-Air-de-MacBook:~ macbookair$ sudo mkdir -p /Volumes/EFI
MacBook-Air-de-MacBook:~ macbookair$ sudo mount -t msdos /dev/disk0s1 /Volumes/EFI
mount_msdos: /dev/disk0s1: Resource busy
MacBook-Air-de-MacBook:~ macbookair$ ls -lR /Volumes/EFI
