I dual boot windows 7 and 8 and I accidently converted my windows 8 disk to dynamic while I was in 7.



I used AOMEI Dynamic Disk Manager to turn it back to basic, but it removed my EFI partition. Now windows 8 won't boot.



Is there any way I can install the non-EFI bootloader on the windows 8 partition and use legacy mode?



Or recover the EFI partition?



Or create an EFI File on a usb - anything so I can boot back into my windows 8!!



Using the windows recovery CD or reinstalling isn't an option.



I need help fast to get the windows 8 booting again!

  • Can you switch to a non-EFI installation at this point, no, you cannot.

  • As I understand EasyBCD can help you. And maybe this is possible duplicate of this?

Easy fix.



Firstly, change the disk to MBR rather than GPT, make sure Windows 8 partition is primary.



Get a copy of bootsect.exe and bcdboot.exe from Windows Automated Installation Kit



Run bootsect /nt60 E: /s E: (change E: to Windows 8 Partition)



Run bcdboot E: /s E: (change E: to Windows 8 Partition)



What this does is changes the disk to MBR to allow BIOS booting, installs the bootloader and created a BCD store on the Windows 8 partition, allowing it to boot without the plague called UEFI. You will need to ensure legacy boot mode is enabled on your computer.
