Partition Disk cloning using dd to KVM with UEFI -> BSOD! or nothing
Hi,
I have read a good documentation
(http://fds-team.de/cms/articles/2013-12/use-a-real-windows-7-partition-in-virtualbox-kvm-vmware-player-u.html)
explaining how to use a physical disk/partition and clone it to KVM image. I am wondering if someone has some how-to with an UEFI partition?
My objective is to clone a partition of Windows 7 from a physical disk. (not the entire disk as it is a 256GB disk and my disk on my host is as well a 256GB so I would not get a byte of free space doing that! only need to clone the root partition of Windows which is around 80GB).
When I plug the disk into my host, I tried a
|dd if=/dev/sda2 of=image.raw bs=512|
(where /dev/sda2 is my 80GB Windows Partition).
If I tried to do a
|qemu-system-x86_64 -enable-kvm -vnc :0 -k fr image.raw|
But my KVM is told me
|Booting from Hard Disk...|
and nothing more!
I have installed OVMF and tried with -L option but I don't succeed. I already know that it is not ideal (because of drivers and lot of other reasons) to do that but the Windows installation is made by my company and I would like to not loose it..
Many thanks for your help!

Don't you have to copy the first few sectors of the hard drive?

Yes, and for UEFI you also need to copy the EFI system partition.
