virtual environment by VMware converter, this post shows you how to do a VirtualBox P2V with Microsoft utility disk2vhd. This method gave few errors and issues after the conversion but I managed solve it and boot the virtual disk2vhd io error machine successfully. Let’s see how to solve these possible errors and do VirtualBox P2V disk2vhd error snapshotting volumes with Microsofts's disk2vhd successfully. Unfortunately this method works on Windows Operating Systems only since disk2vhd is from Microsoft.This utility converts the virtualbox a disk read error occurred vhd physical hard disk partitions to VHD (Microsoft Virtual Disk) format which can be used on Oracle VirtualBox. Migrating a working physical Windows computer to VirtualBox platform is very easy by this way. Once it https://social.technet.microsoft.com/Forums/office/en-US/14e4085c-c28e-4076-a4e5-f43f127d5cd4/disk-read-error-occured-vhd-using-disk2vhd?forum=winserverhyperv has been converted to VHD format, it can be used with VirtualBox which runs on any OS like Linux or Mac OS X.In this example, I converted my physical computer which is having two Operating Systems (Windows 7 and Windows XP), but Windows 7 to VirtualBox P2V.Steps for VirtualBox P2V with disk2vhd and Fix Errors.1) Download the latest version of disk2vhd (2.01 version)2) Installation is not required, run the http://www.sysprobs.com/virtualbox-p2v-disk2vhd-errors-fix program directly.3) It will pick up the physical hard disk partitions from host OS.Important Note: My mistakeBefore go to next step, let's understand something clearly!If you want to convert your entire physical disk (for example 500GB with 5 partition) to VHD, then select the all partitions and start the conversion. This will not cause any issues while attaching the VHD to VirtualBox or Virtual PC, except space issue because the converted VHD file will take the same size as 500GB.But, if you want to P2V only specific Operating System and partitions from physical computer, then you must do it properly to avoid problems later.In this example, I like to convert my working Windows 7 host to VirtualBox. So, I must convert the System and boot partitions which are mostly different.Here is my working Windows 7 physical computer.Initially I have converted only Windows 7 boot partition (normally C drive) to save space and time. I know this is not the system partition with boot recorder, but I had the confident to repair and boot virtual machine if it fails to boot later.No matter how many partitions you select and convert, VirtualBox will detect the VHD as the size of full physical disk with correct partitions.

Windows Server 2008 to 2008 R2 was planned anyway. The questions raises what to do with exsiting virtual machines? One of the reason to use virtual environment was to decrease the need of reinstalling OS every time we need to move it to another hardware. The solution was found in form of the vmdk2vhd utility supported by numerous success stories of such migration.This page contains quite extensive explanation how such migration should be done. One of the most important steps is to check whether the existing machine uses IDE or SCSI controller on the boot drive. Hyper-V doesn't boot virtual machines from virtual SCSI controller. I followed the steps described in the article and expected everything to work fine. Even better, some of my VMWare machines already had IDE controllers on a boot drive.So far so good but when all disks have been migrated and I created quite a few new Hyper-V virtual machines, none of those started up. There were two types of errors:For bigger virtual disks I got a message "Disk read error. Press Ctrl+Alt+Del to restart" on a black screen.For the other machines I got Windows booting but crashing in a couple of seconds with the BSOD.After spending hours of reading excessive number of posts in different forums and blogs I managed to resolve both issues. So first I understood the reasons of these issues:"Disk read error" occures after vmdk to vhd migration because MBR or partition table is not valid for the disk size. This might be a bug in vmdk2vhd, I have no idea but this issue is definitely related to the hard drive geometry.The second issue is known as famous "inaccessible boot device" BSOD error. It only occured on those machines that used to have SCSI drives as boot devices, although I followed the instructions to avoid this problem (may be not very carefully).Now we get quickly to the solutions of both problems:Hard drive geometry can be fixed using the teskdisk utility, which also runs on Windows. What needs to be done is simple - use Disk Manager to mount the corrupted virtual disk and run testdisk. Further steps are very well described in the following atricles:Testdisk Step By StepRebuilding NTFS boot sector using TestdiskWhen you are done with testdisk, don't forget to save the new partition table and quit the utility, after that unmount your virtual disk in Disk Manager. Try starting the machine in Hyper-V and it should not give you "Disk read error" anymore.The IDE driver must be injected to the offline Windows machine, in the system registry. Although it sounds quite dangerous, it can be done quite easily since we again are able to access the
