When you first time open that drive with for example with fdisk it complains about incorrect mbr. If you in that situation print the partition table you will see that the device id is null. When you create a partition these errors will be corrected by write. Fdisk creates a new device id from random data. It is then written to the mbr. Just explore the disk with hexedit and you'll find the device id. Just remember endianess. By the same way a UUID is created when you format a new NTFS partition. It is also just random data written to the disk. It can easily edited with hexedit. At least my win7 booted normally when i moved it from a disk to another and fixed the UUID's of the new drive. Windows didn't notice anything. After i switched the motherboard of the machine then windows required a new activation. Actually if you copy the windows partition with dd the uuid of the NTFS partition will not change. If you also copy the beginning of the old disk to a new one it will copy the device id to the new disk. Instead if you make a new partition table the device id will change. There is nothing magical with partitioning and moving data on disk or to another disk. You can completely wipe mbr and partition table and then write a new partition table with partitions pointing to the beginning of your data and all your data will be intact. Just experiment with hexedit. I can give you correct addresses when i'm back at home tomorrow. Or just google your self, if you are unable to find it with hexedit. -- Matti

Like most things MSWindows related you will need patience which in my case
runs short - at some subconscious level I consider spending time on MSWindows
a resentful waste of my life ... but YMMV.
It used to be simple enough, until the Vista-disaster was launched. In any
post Vista OS you will find that the boot system files have changed somewhat.
First of all from Windows 7 onward there is usually a separate boot partition.
Second, you now have to use the bcdedit.exe command to edit the 'boot.ini'
file. Third, the plain text 'boot.ini' file is no longer called boot.ini
and it is no longer a plain text file, but binary. :-(
So, the new boot.ini is called BCD and if you search for it through your
MSWindows partitions you will eventually find the partition with the boot
files. The BCD file is in the hidden (for MSWindows) Boot directory, in a
separate from the OS boot partition:
ls -la /mnt/Win7/Boot/BCD
-rwxrwxrwx 1 root root 36864 Mar 9 08:57 /mnt/iso/Boot/BCD
(here I have mounted the MSWindows boot partition under /mnt/Win7/)
To view its contents, boot into MSWindows and run in a console:
C:\Windows\system32bcdedit /v
(assuming that your OS partition is mapped to C:\ drive).
You will need to change the UUIDs for the MSWindows OS and for the boot
partitions (called GUID in MSWindows) using the bcdedit command, one line at a
time. It is primitive compared to a Linux text editor and painful if you make
a typo, but that's MSWindows for you.
The MSWindows boot partition will have the identifier {bootmgr}, while the
OS would have {current}, or {default}.
To find out what GUIDs your moved MSWindows partitions (Volumes) have, you can
use the diskpart command. Startruncmddiskpartlist disk and diskpartlist
volume. If that doesn't show what you're after, use the GWMI command in
MSWindows powershell:
GWMI -namespace root\cimv2 -class win32_volume | FL -property
Label,DriveLetter,DeviceID,SystemVolume,Capacity,Freespace
For more info have a look here, from when I fought setting up a MSWindows dual
boot system by chainloading grub:
http://thread.gmane.org/gmane.linux.gentoo.user/226452/focus=227265
PS. For bcdedit options see these links:

I have an Ideapad y510p that's dual-booting Win8.x and Gentoo. It
shipped with 8.0 and after I got it dual-booting I upgraded to 8.1.
It's not quite the same model, but I guess it can't hurt to type what I
remember. I didn't take notes, because if I ran into any trouble it
was my plan just to wipe the drive and install only Gentoo. I just
flew by the seat of my pants, so I'm sure this isn't the smartest way
to do things.
My model came with a smallish SSD meant for caching. The SSD is sda and
the HDD is sdb.
Here's the current state of sdb, from gdisk:

1121583872 1562466303 734.8 GiB 0700
sdb1-sdb7 existed on the drive when I got it. sdb5 is where Windows is
installed. To make room for Gentoo, I shrunk sdb5 it and slid it to the
end of its space using the GUI partition tool on System Rescue CD,
which I think is gparted. I also used System Rescue CD to install
Gentoo. It's important to boot System Rescue CD in EFI mode, at least
for installing the bootloader.
sdb8 is meant for an installation of System Rescue CD, but I haven't
gotten around to installing it.
sdb9 is /boot, sdb10 is swap, and sdb 11 is Gentoo /
I emerged grub in the chrooted environment. I mounted sdb2
at /boot/efi, installed grub on sdb9 (/boot), and ran grub-mkconfig to
make a config file for grub. The output indicated that it had found
both Gentoo and Windows. The bios (or whatever it's called now)
setup recognized grub as a new EFI-booting option and let me move it to
first priority, and I got to the grub menu.
grub booted Gentoo just fine, but Windows booting failed, something
about not finding partitions or files. Instead of troubleshooting that,
I disabled os probing for grub (GRUB_DISABLE_OS_PROBER=true
in /etc/default/grub) and added Windows via /etc/grub.d/40_custom ,
like so:
menuentry Windows 8.x {
set root='(hd1,gpt2)'
chainloader /EFI/microsoft/BOOT/bootmgfw.efi
}
Running grub-mkconfig after that got me a grub.cfg which works to boot
Gentoo and Windows, though I don't get any fancy options for Windows,
such as safe mode.
If you moved the MSWindows OS or boot partitions then the UUIDs would have
changed. You'll need to edit the MSWindows boot menu (in the MSWindows boot
partition) and change their entrie(s) accordingly.

Not necessarily. You can make uuid identical. It is just data on disk. Even if
you change the order of partitions windows can be tricked with grub by changing
the bios order of drives through mapping. After that windows boots without
modification. I've tested this up to win7. Grub and dd are only tools you need.
