Update on VHD Booting to Windows Server 2008 R2

If you read my last post, you saw I was going to set up the pre-made Visual Studio 2010 beta VHD to boot on my Windows 7 machine. Well, there is no way to make it happen. Unfortunately, the Microsoft made VHD has Windows Server 2008 and not Windows Server 2008 R2.

I guess this means I have to create my own VHD. I was hoping to avoid this, as it is very time consuming. Yeah, I know. WAH!!!

VHD Booting Windows Server 2008 R2 in Windows 7

There is a new article with particulars on my main machine. You can find it here.

I just found another thing to love about Windows 7. With Windows 7, you can boot from a Virtual Disk. I wish I had known this a few months ago when I opted to completely toast my machine to run Windows Server 2008 R2 so I could play with SharePoint and Team System.

Here are the steps outlined (I will likely edit this, as I am going to redo things tonight now that I have learned some things about this scenario). I am going to boot from the downloadable VHD with Visual Studio 2010 and Team Foundation Server installed.

NOTE: Items in italics and underlined that have brackets, {}, around them are placeholders. You will need to fill in your own information. Example {VHD file location} indicates you have to point to your VHD file. I would normally just use the brackets, but one of the command line tools uses brackets for one of the command parameters.


There are many paths you can take, some of which have no requirements other than Windows 7 (or Windows Server 2008 R2, if you wish to use it as your “host” OS).

Creating the VHD

The tools you need really depend on how you are going to accomplish the install. There are three ways to go about setting up your VHD. The first step is creating a VHD:

  1. Create a Virtual Disk using VirtualPC
  2. Create a Virtual Disk using diskpart

Of the two options, diskpart is the quickest. Here are the steps

  1. Open a Command Prompt (Type Windows Key + R then type cmd and press Enter)
  2. At the command prompt type diskpart and then press Enter
  3. Type the following commands to create the disk and attach it
    1. create vdisk file={file location} type=fixed maximum={max size in MB}
    2. select vdisk file={file location}
    3. attach vdisk
    4. exit

I generally end up with a fairly large disk size, as I need Team Foundation Server, et al, added.

Setting up the VHD

The next step is to set up the disk, unless you are downloading a VHD to boot from or already have one created. Once you have the vdisk attached, you can use diskpart to set it up:

select vdisk file={VHD file location}
   select the disk you wish to work on
list disk
   find the VHD disk
sel {disk name}
   Once you find the disk, this selects it
create part primary
  creates the primary partition
sel part 1
   Selects the partition so you can work on it
    marks the partition as active
format fs=ntfs quick
    quick formatting as NTFS
    assigns a drive letter

If you follow all of these steps, the partition is active, assigned and formatted.


  • You do not have to use a fixed type drive, but I recommend it for demoing, as it is something you have a bit more control over fragmentation
  • You have to format the disk before installing an image. If you are doing a full install from media, you can format then.

Loading Windows Server 2008 R2

This portion can be done a variety of ways as well.

Download Windows Server 2008

UPDATE: Does not work, as the VHD image is Windows Server 2008 and not Windows Server 2008 R2.

Install from Disk

The easy way to do this seems to be just installing to the disk from a Windows Server 2008 R2 disk, as it adds everything to the boot menu for you. It is also the most time consuming, as you are running a full install. Here are the steps:

  1. Insert install disk
  2. Choose VHD drive

Can’t get much simpler, but you will wait for the entire install to complete. if the VHD is not bootable, you will get a warning that it is not bootable. This does not seem to be a big deal,as the disk appears to be set active and the boot entries are added.

NOTE: If you have not attached the disk, you can install the OS with VirtualPC.

Install from .wim file

To do this quickly, you use ImageX, which is part of the Windows Automated Installation Kit (AIK). You will need the install.wim file from either Windows media or from an installation. If you need to create a custom .wim, you can use the this web page. It is necessary (best?) to have the drive attached and assigned to accomplish this.

In order to do this properly, you need to know the Index for the Image. If you already know this, you can use the number. If not, you can get it by running the following command:

imagex /info {.wim file}

The index is contained in the IMAGE tag (bolded below):

    <TOTALBYTES>{size here}</TOTALBYTES>
    <IMAGE INDEX="{index}">

To install, you use the following:

imagex /apply {.wim file} /check {index} {assigned drive number}

This should take a few minutes. On my machine it is less than 10 minutes, but I would imagine it can take longer on a slower machine.

Adding Entries to Boot to VHD

If you have attached the disk image, you need to unattach it now from a command prompt.

DISKPART> sel vdisk {path to VHD}
DISKPART> detach vdisk

If you downloaded an image or created one via another means, you are fine. The next steps work with any VHD with a correct OS on it (ie, Windows 7 or Windows Server 2008 R2 – or greater (future)). If you installed directly to VHD, you don’t have to follow these steps, as your boot is already configured.

Before doing anything, type in bcdedit and hit the enter key. This gives you a look at the boot loader entries. You shoul dhave one for Windows Boot Manager (not important to us in this exercise) and one for Windows Boot Loader.

First, let’s copy the boot load section for the current install of Windows 7. Type in the following:

bcdedit /copy {current} /d "{alias for VHD}"

NOTE: In the above command {current} is part of the command, not a placeholder for your information. The alias is something you have to configure, however.

Now type bcdedit again and you will now have two Windows Boot Loader entries in the file. Find the one with the alias you created in the last step. You will need the GUID (identifier) to do the next steps.

Run the following to set the file to boot from VHD instead of being another normal C drive entry:

bcdedit /set {GUID} device VHD={path to device}
bcdedit /set {GUID} osdevice VHD={path to device}
bcdedit /set {GUID} detecthal on

When you restart your machine, you should see both Windows 7 and your alias as boot choices.

Final Notes

I have used virtual machines for years to beta test. Unfortunately, running in VirtualPC can be very SLOOOWWWW! This option allows you to use a VHD as a bootable disk, which is quite a bit faster than running in VirtualPC. It is still not as fast as running the OS native.

There are a couple of things you should note with these options, as they may affect your demonstrations, if that is your reason for doing this:

  • Hibernate will not work in the VHD boot image. This means you have fewer power options
  • Bit locker does not work on the VHD boot image. This should not be an issue unless you are using this method to set up numerous boots and storing sensitive information. I keep that on my main OS personally. 🙂

I will follow up in this post once I have my image completely set up and running with the VHD for Visual Studio 2010.

Easing Childhood Cancer Treatment Symptoms

  • I have not written on this subject in this blog, although we have detailed much of the information on Miranda’s site:


I wanted to give out this information, as is. It is not scientifically sound, as a study of 1 is not scientifically significant. Perhaps over time we will amass enough cases we can push for a study on some of these items.

What I describe are Complementary treatments, or treatments to be used in conjunction with standard oncology treatments. They are not alternative treatments, meaning in lieu of standard treatments. Here are two things to keep in mind, one against either side of decisions on complementary treatment options:

  • Always talk over any complementary treatment with your doctor, as there are supplements that interfere with chemo (selenium and cisplatin come to mind)
  • Conversely, when you doctor states “there is no evidence that suggests it works” understand that there is generally no evidence it does not either.

    NOTE: It is unlikely, if the current system persists, there will ever be evidence complementary treatments are effective, as complementary treatments are not generally tested in clinical trials (there are currently 63 for antioxidants with cancer, but most are aimed at abating symptoms, none deal with antioxidants at the same time as chemo – on the other hand,, there are 354 trials for actively using trastuzumab (aka, Herceptin) in cancer treatment – 63 for antioxidants and 354 for 1 drug).

We found nothing in what I write about here that goes counter to standard treatment, nor did Miranda’s primary oncologist. We also found great success with each of the items mentioned. But, as I will state over and over again, a study of one is not a scientific study. At best it is anecdotal evidence. If I had to do this over again, I would have started these methods earlier to completely avoid the pain.


In September of 2007, Miranda was diagnosed with Ewings Sarcoma, a rare childhood cancer, at the age of 3. Over the next month, we experienced both the horror of cancer and the horror of the treatments used to fight cancer. once we realized that the doctors main, if not sole, job was to kill the tumor, we felt it necessary to research options to alleviate some of the pain of the treatments.

Miranda’s treatment regimen was 7 cycles of two alternating rounds of chemo:

Round 1 (VinCAid)

  • Vincristine (the Vin in VinCAid)
  • Cyclofosfamide (the C)
  • Doxorubicin (Adriamycin, thus the Aid)

Round 2 (IE)

  • Ifosfamide
  • Etoposide

Many of the chemo agents above can cause severe gastro-intestinal problems. In addition to the above, she was given prophylactic doses of antibiotics to keep infection at bay, killing off much of the gut flora.


First, what is mucositis? Mucositis, in simple terms is swelling and the formation of ulcers in the mucous membranes along the digestive tract. Essentially, it is chemo tearing up the lining of the entire digestive tract. One teen boy described it like “getting a potato chip stuck in your throat”, but the pain being thousands of times worse with no way to wash it down.

During Miranda’s first round, she experienced horrible mucositis. So much so, we could not get her to eat. The two most startling symptoms were:

  • A sore that covered almost her entire tongue (imagine a canker sore this size and you get the idea)
  • Vomiting up what appeared to be giant spiders (from ulceration of the throat and stomach)

The doctors gave us mouth wash and pain meds, neither of which seemed to offer much relief.

After the first round, we determined something had to be done and found L-Glutamine. After putting her on L-Glutamine, most of the symptoms disappeared and we certainly never had a round anywhere near as serious as the above.

Our method of choice was mixing L-Glutamine in with her juice and having her drink it. At the time, there was no way to get her to swallow pills, so it was necessary to find something she could drink. You can buy L-Glutamine in powder form and give a scoop once or twice a day to abate symptoms.

The idea that L-Glutamine works on mucositis was noticed by the NCI, who started a clinical trial, which was later withdrawn due to lack of funding. I am sorry to see the trial cancelled as it would be interesting to see if others had the same success we had.

Clostridium Difficile (or C Diff)

C Diff is a opportunistic bacteria that creates a whole host of problems for the cancer patient. You first notice it by its unique odor, which is unmistakable. It is generally combined with very bad bouts of diarrhea. It can be fatal if not treated. The solution to C Diff, from a medical perspective is to give very high doses of strong antibiotics, like Vancomycin and Gentomycin. In Miranda’s case, these led to some rather severe kidney problems. In my book, that makes C Diff a good thing to try to avoid.

We went through three rounds of C Diff early on in the treatment. We then started researching and found that probiotics showed promise against C Diff. C Diff appears to be a rather weak bacteria, compared to the natural gut flora. But it is also opportunistic and grows like a wild fire when the gut flora is killed off. This is common when you use antibiotics as readily as they are used with a child with cancer.

After starting probiotics, we never saw another C Diff infection. We found out later that the main oncology transplant doctor at the hospital prescribes probiotics for his patients.


I don’t have the details on what we used when Miranda had her kidney problems, so I don’t want to write about it here, as incomplete information is useless. We also used a variety of supplements to combat potential future heart problems, including fish oil (anti-inflammatory) and CoQ10 (antioxidant), although we did not use any antioxidants during the actual chemo drip, as doctors state it will render chemo ineffective (there are animal studies that refute this, but none in humans).

Saving an XML file from an XML Query in SQL Server

This is a short one that was spurred by the following question:

Any idea how to export an xml document from ms sql 2008 using vb.net into a
folder some where? I am running an SP that generates the xml already.

The answer is divided into a bunch of sections.

Streams and EndPoints

We have to go back to my previous entry on streams and endpoints (see Understanding Data in .NET). If you read it, you remember that endpoints are where data is persisted and streams are devices to get data from one endpoint to another. Examples of endpoints in this question:

  1. SQL Server
  2. XML file on the file system

I am not going to reiterate the entire article, so read it if you need more info.

XML in SQL Server

If you want to play along, download Adventure Works. I am simply using the Address table in the Person schema. I am running SQL Server 2005 on this particular machine, although I have SQL 2008 R2 on my home machine. It works on any of these (SQL 2005, SQL 2008, SQL 2008 R2).

To select, I have a couple of choices with the FOR XML clause. If I like attributes, I might do the following:

Code Snippet
  1. select Top 1 *
  2. from Person.Address
  3. FOR XML PATH(‘Person’), ROOT(‘Doc’)

This produces XML in elements:

    <AddressLine1>1970 Napa Ct.</AddressLine1>

Or I could choose to use XML RAW:

Code Snippet
  1. select TOP 1 *
  2. from Person.Address
  3. FOR XML RAW, ROOT(‘Doc’)

This creates attributes, but uses the generic name “row”:

  <row AddressID="1" AddressLine1="1970 Napa Ct." City="Bothell" StateProvinceID="79"
     PostalCode="98011" rowguid="9AADCB0D-36CF-483F-84D8-585C2D4EC6E9"
     ModifiedDate="1998-01-04T00:00:00" />


Code Snippet
  1. select TOP 1 *
  2. from Person.Address
  3. FOR XML AUTO, ROOT(‘Doc’)

This produces the name Person, which it figures from table name

  <Person.Address AddressID="1" AddressLine1="1970 Napa Ct." City="Bothell" StateProvinceID="79"
      PostalCode="98011" rowguid="9AADCB0D-36CF-483F-84D8-585C2D4EC6E9"
      ModifiedDate="1998-01-04T00:00:00" />

There is also FOR XML EXPLICIT for more complex examples, but I end up having to create the “map” of the elements/attributes to use this format. The method is not important to this post. I just show the following to give an idea of what SQL Server does.

NOTE: Each of these examples has a full XML document. If I merely want snippets I drop the ROOT portion of the statement.

Getting the Data

There is no reason to format this data into objects, so we can pull it with a SqlDataReader. Here is a very simple pattern:

Code Snippet
  1. string connectionString =
  2.     "server=(local);database=AdventureWorks;Integrated Security=SSPI;";
  3. string sql =
  4.     "select Top 1 * from Person.Address FOR XML PATH(‘Person’), ROOT(‘Doc’)";
  5. SqlConnection conn = new SqlConnection(connectionString);
  6. SqlCommand cmd = new SqlCommand(sql, conn);
  7. try
  8. {
  9.     conn.Open();
  10.     SqlDataReader reader = cmd.ExecuteReader();
  11. }
  12. finally
  13. {
  14.     conn.Dispose();
  15. }

The reader now contains the data. Of course, the above snippet does nothing other than sets things up.

Outputting XML

If all we want is a file, then we could do this with a StreamWriter. Something like this:

Code Snippet
  1. string connectionString =
  2.     "server=(local);database=AdventureWorks;Integrated Security=SSPI;";
  3. string sql =
  4.     "select Top 1 * from Person.Address FOR XML PATH(‘Person’), ROOT(‘Doc’)";
  5. SqlConnection conn = new SqlConnection(connectionString);
  6. SqlCommand cmd = new SqlCommand(sql, conn);
  7. try
  8. {
  9.     conn.Open();
  10.     SqlDataReader reader = cmd.ExecuteReader();
  11.     StreamWriter writer = new StreamWriter("C:\projects\test.xml");
  12.     while (reader.Read())
  13.     {
  14.         writer.Write(reader[0]);
  15.     }
  16.     writer.Dispose();
  17. }
  18. finally
  19. {
  20.     conn.Dispose();
  21. }

Fairly straightforward. This will not check the validity of the XML, but we are fairly confident it is valid as is. There are enhancements we could make if we needed to validate the XML, etc. We could also move into other readers and writers.

The main takeaway here is that the reader is effectively streaming data from the database and the writer is taking that stream of data and writing it out. I wish I had a bit more time and could play with this some more, but this solves the problem at hand and alleviates having to explain XML.

December NNTP Client Bridge Beta Released to Public

Like using the Microsoft forums, but prefer an NNTP client to interact, the NNTP Client Bridge is now available for everyone. The product is still in beta, but it is essentially a proxy client to connect an NNTP client, like Windows Live Mail, to the Microsoft forums. You can download it from Microsoft Connect.

If you have not used the NNTP Client Bridge yet, read this post. You will have to have the client bridge started prior to attempting to post, as it is a proxy. If it is not running, you will end up with a failure.

Update on Miranda

For those who do not follow Miranda on her site, but have been asking about her, here is an update.

First, a cute picture taken at the Macy’s breakfast for Make-A-Wish. Here is Miranda with Santa:

Full Page: http://www.flickr.com/photos/20449779@N06/4203735100/in/set-72157622918529097/

As you can see, other than the short hair, she looks like any other five year old girl. And since some mothers do cut their girls hair short, there is not much to show here.

She had her last scans the first week of December and she is still NED (No Evidence of Disease). The next scans are in April, if I remember correctly. We have moved out the schedule a bit, which is nice. one and half years down and three and a half to go. She is now at the point when most children relapse, so the tension will be going down after her April scans.

Here is one of all of the girls:
