Thanks for this. I had a question about this. I sent it to you via PM.
I followed you how-to but I needed to read loads of microsoft tech doku to get on.
I started in windows 7 pro x64 an executed gdisk.exe from sourceforge.net (gpt fdisk o.6.4)
It started to convert MBR to GPT but then suddenly I had a blue screen with "partitionmgr.sys"
I booted my ubuntu live dvd. Started gParted and thank good all Data alive (I made a backup before).
And the System SSD is marked as GPT.
Then I thought I shall boot from the Win7 DVD in UEFI mode (I have an ASUS P8P67 Pro, with UEFI)
I did this.
But after the "windows files are loaded" it did stop at the green progress bar. It just didn't start the Setup, it did run that bar forever.
Then I deleted my 100MB EFI system Partition in NTFS, which was left from the old MBR system. It contained the bootmgr stuff.
I then created a 100MB FAT32 an flagged it "boot" with gParted.
I then resized my 75GB Windows Partition to make space for a 128MB MSR Partition
I then launched a VISTA PE live DVD (because the win7 didn't launch, as mentioned above) and started diskpart.
I created a MSR partition.
And used totalcmd to copy the c:\windows\boot\efi files to the newly created an mounted 100MB fat32 Efi partiton (J:\EFI\Microsoft\Boot\)
Now I hope I can boot the UEFi DVD mode correctly to let the Win7 setup build the BCD.
It booted from UEFi-DVD and repaired the BCD.
I then went to the BIOS/UEFI and selected "run efi shell from file system device" but aber some seconds it did pop up a window with the heading "warning" and in the windows only written "0".
And the I was back in the BIOS/UEFI.
Now I have not only my SSD, HDDs and the DVD as Boot-Device but also "Windows-Bootmanager".
I did boot from the "Windows-Bootmanager" entry.
It now displays "Windows Error Recovery"
I will select "start windows normally", other options are safe mode, safe mode with networking and safe mode with command prompt.
Now it does make a checkdisk on the NTFS Windows partition.
I'm back on my system. What a nice an relaxing feeling. All Data ok.
Thx for your how-to.
I tried doing this, then ended up with nightmares with an autochk not found error and the following error:
THE SESSION MANAGER INITIALIZATION SYSTEM PROCESS TERMINATED UNEXPECTEDLY
WITH A STATUS OF 0XC000003A
THE SYSTEM HAS SHUT DOWN
For anyone else who does this, after a lot of effort I found an easy fix. You need to map the drive letter C to your main partition. You can probably do this with diskpart from the Windows Recovery CD, though I used Disk Director.
