Windows 10 fails to boot after installing reFIT

Hi! Im running Windows 10 on Macbook late 2007 installed via Winclone ( i'm not using Boot Camp at all, disk was partitioned by Disk Utility before install in FAT32 - winclone converted it in NTFS) .

Everything works fine before i'm suggest to install reFIT and repair disk in Disk Utility.

Now i can't see option Windows when mac starts and i'm holding "option".

I'm suppose that i'm try everything from this thread :

1) Hybrid MBR

3) Make a partition in gdisk

2) Make bootable flag in fdisk

I think I made a mistake somewhere because you do not know what else to do.

here is my config:

diskutil list

If you used Winclone, there is not need to rEFIt. rEFIt is old. rEFInd is the newer branch. How were you asked to use rEFIt? What is the source Mac year/model of the Winclone copy of W10?

I don't know for what reason i'm installed reFIT - may be i think it will help me to make a Windows partition primary.

Now reFIT uninstalled.

I don't know what source of it - i'm downloaded it via torrents. It was a 8.1 before - than i'm upgraded it to 10.

It was only images (ISO) of windows 8.1 converted in Winclone

The W8.1 ISO is just an installer. It can be downloaded for free from Microsoft. Winclone will restore an installed Bootcamp/Windows partition. The ISO by itself will not work.

Yes that's right. It's just an winclone image of win 8.1 and after reboot windows perform standard installation.

Winclone was used in tandem with jpkge utility that was asked me in which partition i want to install Windows ( before i'm partitioned HDD in Disk Utility).

I have not working superdrive DVD and this helped me install Windows without any Boot Camp utility and external drive.

I don't know who invented this method. But it works.

UPD:

I'm noticed that Windows partition is not appeared whem i'm locking option key after reboot. But if I do nothing after reboot it tries to boot in windows with message "No bootable media"

I do not see the difference . I have a section 4 is Windows 10. It must be run . What is the problem? I will say more - after some manipulation I had the Windows partition when you press the option . But then I started to do something else , and he was gone . I just need to do the right MBR Hybrid layout i think.

The difference is cloning a VM virtual disk to a physical partition using Winclone and continuing the installation. In your case, you only have the ISO, not a disk/virtual disk which has already started a Windows installation.

Your Fdisk output already shows a standard hybrid MBR. Here is an example from my Mac.

sudo fdisk /dev/disk0

Password:

Disk: /dev/disk0 geometry: 31130/255/63 [500118192 sectors]

Signature: 0xAA55

#: id cyl hd sec - cyl hd sec [ start - size]

------------------------------------------------------------------------

1: EE 1023 254 63 - 1023 254 63 [ 1 - 409639] <Unknown ID>

2: AC 1023 254 63 - 1023 254 63 [ 409640 - 250392096] <Unknown ID>

3: AB 1023 254 63 - 1023 254 63 [ 250801736 - 1269536] Darwin Boot

*4: 0C 1023 254 63 - 1023 254 63 [ 252071936 - 248045568] Win95 FAT32L

If your method is working, the MBR is valid, it should continue or give you an error message.

Not certainly in that way. You do not probably realize - I had fully installed Windows 10 ( not ISO) to partition 4. And it's work for me before i foolishly installed rEFIt and quite unnecessarily I decided to repair the entire disk in Disk Utility. After this Windows partition disappeared when macbook booting.

Why is there no longer boot Windows, I do not know.

Was W10 removed or did rEFIt cause it to disappear? Can you post the output of

sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C

This will show the first block of the partition.

Also, if you had a working W10 installation, what is the purpose of W8.1 ISO?

Hi!I'm tired to find a way to recovery from OS X and decided to install windows again by winclone method.

I'm not sure rEFIt was a cause of disappearing windows partition from boot menu or repairing disk from Disk Utiity, because i'm installed rEFIt and then do repair.

I probably confused you - 8.1 is an image winclone, not ISO that I firstly installed and then later update to 10.

I think that the algorithm of the winclone installer is in partition the drive, make it bootable and then transfer win install files

I am currently working in win- but if you're interested I can send the stat of fdisk and gdisk
