I wonder. I was poking around in bcdedit's help today trying to figure out a way
to boot to an app, and ran across the following. There's apparently a way to
/set a vhd as a boot device?




E:\>bcdedit /? formats

The following describes the formats of the data that are required for
<datatypes> used with the /set command. The format that is required depends on
the <datatypes> that you specify with the /set command. For more information
about the formats associated with each <datatype>, run "bcdedit /? TYPES".

bool A boolean value. The following values correspond to TRUE:

1, ON, YES, TRUE

The following values correspond to FALSE:

0, OFF, NO, FALSE

device A device can be one of the following types:

BOOT
PARTITION=<drive>
HD_PARTITION=<drive>
FILE=[<parent>]<path>
RAMDISK=[<parent>]<path>,<optionsid>
VHD=[<parent>]<path>,<locatecustom>

The options for these types are:

<drive> A drive letter with a colon and no trailing
backslashes.
<parent> (Required) Can be either BOOT, LOCATE, or a drive
letter with colon. The square brackets do not
indicate that this is optional, but are a literal
part of the syntax.
<path> A path to the file (or .wim file) from the root of
the parent device.
<optionsid> The identifier to the device options entry that
contains the system deployment image (SDI) options
for the RAM disk. This is usually
{ramdisksdioptions}.
<locatecustom> Supplies an optional element used to locate a device
within a VHD. The default locate element for a
device is its application path (systemroot for an
osdevice). Custom values must be specified using
custom element sytax (see -help types customtypes),
for example: locate=custom:22000002.

id An entry identifier, which refers to an entry in the boot configuration
data store. Run "bcdedit /? ID" for more information about identifiers.

integer A 64-bit integer type. Some integer types can be set using enumerated
values.

integerlist A list of one or more 64-bit integers, separated by spaces.
This list should not be enclosed in quotation marks.

list An entry identifier list. It contains one or more entry identifiers
separated by spaces. The list should not be enclosed in quotation
marks.

string A literal string. If it contains spaces, it should be surrounded by
quotation marks ("").

That is a rather different thing. That is to allow you to boot the host
machine from a vhd file rather than from its HDD. There are pretty strict
conditions on what OS you can use.

Thanks, so is it possible to create a system image using the backup applet, and
then boot from the resulting vhd? Not to hijack this thread,, do you know of any
good references that describe this?

No, you can't make a bootable system image from the backup VHD.
Please start a new thread instead.

Thanks. I've since done some research and better understand the mechanics and
conditions that you and Mr Grant refer to.
