Possible to load local win7 from bootmgr(not in hd)?

I found that many people have encountered some booting errors that bootmgr is missing. I guess some of them are set C: as active while there's a 100M big Hide Partition before C:, or the other may really have lost the file bootmgr.

I study the win7 for several days to learn that it boots may as: bootmgr ->bcd ->winlogon.exe, then load win7.

I'm making my multiboot DVD, so I now have an idea may solve that problem:
file bootmgr and boot folder on DVD, just add an menu to the file bcd pointing to the "winlogon.exe" which is on local C:.

So when I boot my DVD and choose that menu, it can load the win7 on hard disk C:, regardless of the file bootmgr or bcd on harddisk.

My bcd:


But the menu "Start Windows 7 on local C:\" didn't work as I wish.

Wish someone can clarify if my solution is possible, if so pls give me the right menu or other.
Many thanks!

Help! grub4dos perform an unattended windows installation.

Based on the ISO of Windows XP professional SP3 VOL edition, I've made an Unattended Windows XP SP3 Installation CD(ISO), integrated with office 2003,common applications and some optimizations etc. The ISO tested perfect in Vmware 6.5 .

I decided to make a multi-boot DVD, so the DVD can not only install windows but also boot to DOS/WinPE/LiveCD Linux, ghost for backup and some other usefull functions.
I in all used three method to boot while failed one by one.
I chose grub4dos to do such DVD. Can anyone help to solve this problem? With many thanks!
To make a multi-boot medium, there may be many boot-manager, but I'm only familiar with grub4dos and trust it's so strong and easy to get started.

Method 1.

The easiest way called to mind is just to do an ISO mapping with grub4dos. So add the unattended windows installation ISO file to the grub4dos-boot ISO, then add a menu:


Setup launched but several seconds later after "Setup is loading files" it breaks with a blue screen:


------------------------

Method 2.

I found somewhere that said the file "setupldr.bin" is the loader of the WINDOWS installation CD.

I extract the ISO files to the root of the grub4dos boot ISO, so the catalog structure of the original windows installation ISO and the grub4dos-boot ISO are the same. the grub4dos menu is:

At last I boot the ISO in Vmware, I'm so happy that the installation successfully launches. But unfortunately that's not unattended, it needs user's interaction by every step.

The file "/i386/winnt.sif", to make installation unattended, needn't to be specify anywhere, the installation will automatically load it and perform an unattended install.
But how it doesn't automatically load it when i use grub4dos to load setupldr.bin?

------------------------
Method 3.

I have no idea for a long time. These days I tried another way, use grub4dos to boot into a DOS image, and then launch the windows installation by winnt.exe, because I can specify the answer file by /u: switches to the winnt.exe

First I should add NTFS and CD-ROM support to MSDOS 7.1b, with NTFSDOS PRO 5 and ref. CD-ROM drivers.But when start the installation it immediately breaks displaying "Setup is out of memory and cannot continue. Setup cannot continue, press ENTER to exit."



Then I found resolution in this page:http://www.bootix.de/support/problems_solutions_en.html So I edit the two commandlines but still not work.

The AUTOEXEC.BAT:

The config.sys:


I press "ENTER" to exit, and check the mem info:


I'm a newbie to DOS, so I have no idea yet.

I like method 2, it's easy and can install windows ,but only cannot unattended install.
Can anyone help me solve the problems? It's OK if you have another method, but I'll be glad if using grub4dos as the multi-boot DVD's boot manager. Because I don't know like CD Shell, BCDW, ISOLINUX etc, these are another hard work to learn.
