How to boot Windows 10 with Clover the easy way.

[ipodsky]

The problem.
After installing Clover I couldn't run Windows anymore. Damn..
Since I already got through this pain I’ll tell you how to fix it.
It is turned out to be very, very simple(when you know how) and no additional installations needed. I must say it works a 100% with Win10 and I do not no about other systems.

If you must need to go to windows right now! without changing anything:
Go to Bios -> Boot and just boot(click) from you disk right from there.
However it’s not cool to go every time to you BIOS to load Wins.
You get sick of it quite soon.


If, from very start you install Windows with UEFI partition than Clover would let you run Windows with no problem.
If it doesn’t work - your C drive in MBR mode and you don't have that extra UEFI partition.
It means, or you need to reinstall system in UEFI mode or know the method HOW to change it without distorting! your system.

Fortunately, in Win10 it’s one minute deal and done with built in Win10 !MBR2GPT.exe!.

For somebody at first it may look scary, but it is not and very simple thing to do.
(Before this little surgery I took all other disks out of my machine.)



Lets do it.


1.Click Start
Search for cmd.exe
Right mouth
Run cmd.exe as !Administrator!

First we’re only testing if it will work or not.
CopyPaste next line(validate means test) :

MBR2GPT /validate /allowFullOS

You’ll get:


C:\WINDOWS\system32>MBR2GPT /validate /allowFullOS

MBR2GPT: Attempting to validate disk 0
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
MBR2GPT: Validation completed successfully

This means it’s OK to convert!

2. And now lets really convert.
CopyPaste:

MBR2GPT /convert /allowFullOS

This is what you’ll see:

C:\WINDOWS\system32>MBR2GPT /convert /allowFullOS

MBR2GPT will now attempt to convert the default book disk.
If conversion is successful the disk can only be booted in GPT mode.
These changes cannot be undone!

MBR2GPT: Attempting to convert disk 0
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
MBR2GPT: Trying to shrink the OS partition
MBR2GPT: Creating the EFI system partition
MBR2GPT: Installing the new boot files
MBR2GPT: Performing the layout conversion
MBR2GPT: Migrating default boot entry
MBR2GPT: Adding recovery boot entry
MBR2GPT: Fixing drive letter mapping
MBR2GPT: Conversion completed successfully
MBR2GPT: Before the new system can boot properly you need to switch the firmware to boot to UEFI mode!

C:\WINDOWS\system32>

3. That's it. Your Win10 disk has extra partition and it's UEFI.


4. Now you must go to your !BIOS! and in Boot you need to make boot in !UEFI mode!.
DONE.

The last thing.
Connect your OSX drive, go to BIOS one's more and assign UEFI partition with Clover as your startup. Now when you boot you can see your Clover and boot to OSX and Windows.

Cheers




ps
This is official explanation of it, but he runs from Windows PE disk or something(??…).
And I found/googled the way to do it strait from my fresh Win10 install.

....and of course....mine fails on MBR2GPT /validate /allowFullOS
