Hi all,

I am making a tool to clone hard drives. I successfully clone windows 7 but the problem is arising while booting the clone disk.

Before putting my queries about windows 7 I would like to explain some thing about other Windows OS beside Windows 7.
As we know each hard drive has its signature that is written in MBR of hard drive just before partition table. This hard disk signature is unique for each hard disk that is connected to machine. In case of Windows Vista and XP this disk signature does not make effect on booting process of OS. If OS find that there is same disk signature in more than one hard drive then it change it randomly-(no effect on booting process). If I manually change this disk signature or do it zero then Vista and XP both boot smoothly and assign a new disk signature to hard drive.

NOW move to windows 7----> I install windows 7 and let it make a small System Reserved partition of 100MB and install windows 7 in C: drive of my hard drive.
The disk signature that this hard drive has is suppose (AB BC CD DA). If I make change in to this disk signature then machine does not boot and one error message appears "Windows failed to start. A recent hardware or software change might be the cause". It means windows 7 depends on disk signature.

After some research I came to know that the disk signature is written in BCD file. this BCD file is in Boot folder of System Reserved Partition. It means this signature is configured in to BCD during installing the Windows 7.

when I clone disk0 to disk1(I clone sector by sector from low label) then this BCD file also copied to disk1 and inside this BCD file source disk signature is configured and disk1 disk signature is different from that. Due to this reason this clone disk does not boot. If I replace disk1 signature in all the places of BCD file then clone disk easily boot. It means I need to configure BCD according to destination disk(disk1) before cloning or some thing else so that the problem can be resolved.


In Windows Vista before cloning I need edit BCD by executing some commands that are- bcdedit /set {bootmgr} device boot
bcdedit /set {default} device boot
bcdedit /set {default} osdevice boot
After running these commands booting with clone disk issue has resolved.

In same way for windows 7 are there some commands or any other utility that can configure BCD?


Please suggest me some way.

Thanks
Madan

Well, I've screwed up my W7 bootloader/bcd while fooling around with different installs. turned out I had to use repair disc to get by bcd repaired, etc. Now, however, my formerly beautiful windows 7 boot screen/logo is replaced by the hum drum Vista logo, with scrolling bar...

Anyway to get back my pretty moving windows logo? I've tried the code below, and cmd tells me that operation completed successfully, however I still have the old scrolling bar logo...

Code:
bcdedit /set {current} locale en-US
someone somewhere said that the locale does not get correctly set in system recovery/repair disk's bootrec /rebuildbcd command, and this is supposed to fix the problem. didn't work that fancy for me.

Thanks for any help

I just unpluged all my raid staff , erased Win7 partition , and reinstalled , this time Dual boot works fine , after all , I plug again my raid staff , and all is working fine without any bcdedit knowledge .

Anyway for people like me , who is making crazy with bcdedit there is a easy-solution, to make or change boot options in vista and now in Win7.

EasyBCD 2.0 BETA fully supports Win7

I'm sorry it took so long for me to capture a screenshot of my disk management screen, I had other matters to attend to. Anyway, here she be.
The largest partition is Windows 7, 50G is experimental OSX, then Ubu 9.10 ext4 fs + swap at the end. Also, you may notice OSX partition is active, that's b/c I am using Chameleon's GUI bootloader loaded onto OSX partition. The new flying windows existed after first install of Chameleon, but after repairing with startup CD (using DISKPART) I get the old windows (vista) boot screen w/green scrolling bar instead of pretty new Win NT 6.1 flying windows animation.
Thanks for any and all help.
