Windows Boot Manager error, winload.exe

Hello,

MacPro 3,1

Windows 7 & 10.9.5

Mac OS and Windows partition on same disk

I've been reading threads here on the apple board and elsewhere on the net. Tried the easier fixes with no luck. (No USB devices on boot, zapping Pram, CommandS fsck operations, etc)

I've had no hardware or mac os updates in a very long time. Bootcamp was working fine for years, then suddenly not working.

I'm wondering if I do have some corruption going on..

My Windows 7 (64), is a Vista upgrade

DiskUtil list

Diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

Many thanks for any help!

Andre

The command we used does not repair the GPT. To repair it, we need to run GPT FDisk in interactive menu. See https://www.rodsbooks.com/gdisk/gdisk.html for reference. A reboot can re-order disks, so be careful.

You need to run (do not type text like this). Let us try to repair disk0 (your macOS disk). Be careful, in each menu, the one-character command can mean different types of requests.

sudo gdisk /dev/disk0

2 (Choose 2, if prompted)

p (print)

x (Experts menu)

n (New Protective MBR)

o (print Protective MBR)

p (print GPT)

w (write the updated GPT)

y (confirm write)

q (quit, if necessary)

Do not reboot. Now post the output of

diskutil list

before we go further.

Ok, hmmm this next step seems a bit daunting.. hopefully there will be no errors between the Start and End values.

I'm wondering if I should just leave everything where it's at... the Mac OSX is back (and the most important part of this 3,1 computer)

The Bootcamp Windows 7 OS functionality, seems like taking a great risk to restore. Being somewhat risk averse, I'm wondering if I should just let sleeping dogs lie...

The long string of commands in repairing the GPT, trying to resurrect BootCamp... do you feel we are taking great risks to the whole system? If so, maybe I'll just leave everything as is... and move on...

thoughts??

Yes, it's mounted on the desktop, TechToolPro sees it as does Disk Utility.

I can select it in startup disk, and holding down the option key

however, once it's starts the windows booting process...

The Apricorn/Aura combination has quite. Few issues.

You will need to use DVD.

The normal Windows installation uses the SATA connection. If you use teh Apricorn, then you may also need eta drivers or teh card to be able to see the SSD. Apple BC drivers do not include these.

Can I run GDisk in terminal, off the TechTool Pro eDisk Mac environment?

It appears GDisk tools are all windows programs, no?

The command is "-l /dev/disk1". It is a minus sign followed by a lowercase L followed by a space followed by "/dev/disk0" or "/dev/disk1".
