[SOLVED] MSI laptop Dual Boot nightmare

Hi guys

(I have had previous experience dualbooting win7x64 and ubuntu 12.04, also win7x64 and opensuse 13.1)

Laptop: MSI GE70 2pc Apache
Preinstalled windows 8.1
attempted install Mint 17 x64 Cinnamon
Boot-repair log:

So I bought an ssd, used minitool partition wizard to partition it for linux and clone my data and windows drives, and created a GPT for the drive.

I know the drill:
turn of fast boot (in windows and bios)
turn off secure boot
turn off intel speedstep
I HAD TO turn off UEFI into legacy, otherwise the LiveUSB just would not load, even after custom boot params in grub, its just a black screen.
used LiveUSB (made with Rufus) to install Mint to the ssd which was attached using an external hdd case.
It worked.
then used boot-repair to make Mint EFI. But it bombs out.

put the drive into the laptop, taking out the original,
didn't boot for nothing, regardless of how much a i played with the settings.

So I'm all out of ideas, definitely kicking myself for not waiting for the HP I wanted to come into stock. (You hear that MSI)

P.S. my windows is stuffed, I don't think it survived the clone. gonna try a recovery disk, see if I can get that atleast booting.
It's related to not finding an efi file, which I think boot-repair is to blame for

You might be able to rescue your boot process with rEFInd

Thanks for that, looks promising. Will definitely give it a go. I've been looking for something like that for my desktop for a while.

Ok so have refind installed. It works very well, can get into Mint 17 without issues, with UEFI on.
I still have some screwy boot entries from boot-repair that I will fix later.

The problem now is my windows is still screwed. I think I know why.
Its because I cloned it from another drive so the GUID is different.
so when it boots up, it gives me error 255 that it can't find winload.efi which is on my "C" drive, in windows/system32/boot

So what I need to do is tell the the EFI entry in the boot partition that it needs to look for windows at a different GUID.

(THis is all speculation, but it makes sense)

I have NO idea how to do that.

Like I said, I have Mint, but I also don't have a recovery disc for windows. and EasyRE doesn't work because the bootloader for UEFI is VEEEEERYYY screwy on the MSI. literally the only thing that has successfully booted in UEFI off of a USB was refind made by rufus.
