Would like to get some assistance: Device: Macbook Pro 2010 13"

Previously I was successfully install windows by manually create partition, format partition to hybrid GPT/MBR by following a guide. And windows working fine, everything normal until one day I am thinking about install linux so I can have complete 3 OS on mac. And I just carelessly install it and linux installation failed, microsoft partition got affected and OS gone. So I delete partition and now MacOs own fully the disk and partition.

The issue now, I am trying to install windows again and its all working until EFI boot on flashdisk done. When turn on mac and hold option button and the "EFI BOOT" appear as installing windows. When we click or press enter, thats it. Its freezing for a moment and will reboot again.

Anyone can help to advise on what to do? I have tried to repair disk on MacOs recovery. But nothing seems work. If anyone have solution or advise I will be open. Thank you in advance.

Instruction I followed previously which was successfully installed windows without bootcamp: https://bit.ly/2JiffBl

I wish Mr David Anderson >> https://apple.meta.stackexchange.com/users/107222/david-anderson can have a look as well and advise what to do as previously I followed his instruction and all is well until I am carelessly tried to install linux without further research.

Will clean install High Sierra OS fix the issue??

  • @lx07 Thank you sir for advising and I will try. So may I know what cause the bootloader wont let me access the windows installer? Coz been trying to research online for days and some say if its iMac it have relation with the graphic cards or something. But since this is macbook pro I dont think its the case, right?

  • @lx07 I think after trying to delete partition, reinstall MacOs its back to normal. The issue now no matter what I tried like doing "first aid" in the recovery mode. Will not fix the boot to start windows installation. Its just freeze without processing anything. Will paste the 'p' here. Mar 28, 2020 at 20:25

1 Answer 1


After trying and search solutions for days with getting no answer I finally resolved it myself by:

Backup macOS using CCC to another harddisk

Also need to make sure regarding the format of drive since I was unable to use the exFat format and need another solution to make it readable in my MBP OS High Sierra. So, I decided to continue follow the instruction but with FAT32 format of USB and partition. For now I successfully have macOS, Windows 10 and Linux on my Mac and mission complete.
