Stop 0x0000007B after converting an existing XP machine to a Virtual Machine (ESXi, Hyper-V, or other)

Posted by jpluimers on 2022/03/22

In 2015, I posted P2V of an existing XP machine to Hyper-V to have an emergency fallback when retiring old XP physical machines and did a short edit on 20210727 promising about a future article on trying to fix the [Waybackstop 0x0000007B blue screen.

This stop can that can happen during boot when the converted Windows XP requires different disk drivers than the physical Windows XP. Windows Vista and up are smarter to figure out the required changes, but Windows XP wasn’t.

The above screenshot is actually from the same physical Windows XP machine after doing the conversion, I wanted to try and run the virtual machine on physical hardware close to the original before moving it to the actual VMware host (yup, the Windows XP machine had been used as a VMware host before, so it had both VMware Workstation 6.5 and VMware Converter 4.01 installed).

The reason I wanted to move my last Windows XP machine to a virtual machine was that it was the only computer that could still print to my old, but nice, Olympus P-400 color dye sublimation printer. I mentioned this in 2015 when Installing the PIXMA mini260 – Canon Europe drivers under Windows 8.1 x64 – trying to say goodbye to Windows XP

I need to find a way to get my [Wayback/Archive.is] Olympus Camedia P-400 Digital Color Photo Printer. That is a lot harder: the latest Windows [Wayback] P-400 Printer > Software Downloads are for Windows XP.

At the end, of the blog post are a few links on the stop 0x0000007B and the Universal Boot CD for Windows workaround.

Always use SCSI for your VM guest disks – Jeroen Wiert Pluimers – Google+

Posted by jpluimers on 2020/01/20

Rephrased from [WayBackJeroen Wiert Pluimers – Google+:

If you install a virtual machine, ensure the disk controller and disks are SCSI based.

This has many advantages, including:

  • speed (usually the SCSI drivers can be paravirtualised)
  • hot addition of new disks

It holds for virtually any virtualization platform including all non-ancient (less than ~10 year old) versions of:

  • VMware (Workstation, Viewer, but I expect this also to work on vSphere, ESXI, Fusion)
  • Hyper-V
  • KVM (and therefore Proxmox)
  • VirtualBox

Based on my notes in the above link and the links below:

Note this isn’t just for Linux guests/hosts: Most guests (including Windows) can do a SCSI bus re-scan and detect new SCSI devices.

The trick here is that the guest must already have a virtual SCSI controller (adding that will require a reboot of the guest).

Then adding a new SCSI disk on that controller from any host (Windows, Mac, ESXi, vSphere) should work fine.

Check If A Linux System Is Physical Or Virtual Machine

One day I am going to try to extend this for a few other virtualisation environments and Linux distributions: [WayBack] Check If A Linux System Is Physical Or Virtual Machine

SysInternals sdelete: zero wipe free space is called -z instead of -c

Posted by jpluimers on 2016/09/20

In the 2009 past, sdelete used the -c parameter to zero wipe clean a hard drive and -z would clean it with a random pattern.

That has changed. Somewhere along the lines, -c and -z has swapped meaning which I didn’t notice.

This resulted in many of my virtual machines image backups were a lot larger than they needed to be.

The reason is that now:

  • -c does a clean free space with a random DoD conformant pattern (which does not compress well)
  • -z writes zeros in the free space

Incidently, -c is a lot slower than -z as well.

TL;DR: use this command

sdelete -z C:

Where C: is the drive to zero clean the free space.
