Tricky BCDEDIT Setup... Help Needed...

Hi Everyone, this is my frist post on this forum, seems to be a helpful resource...

This is my question:

I have two Hard Drives, 128GB and 500GB.

Disk0 = 128GB
Disk1 = 500GB

The 128GB consists of two partitions, each 64GB.
The 500GB consists of only one partition, 500GB.

I have Windows 7 64bit installed on Disk0, Partition0 (64GB)
I have Windows XP installed on Disk1,Partition0 (500GB)

This is what I want to do;

I want to install Windows 7 32bit on the second partition on disk0, Partition1, but I'm not sure how the BCD entry in my bootloader should look like. You probably wondering if I'm installing Windows 7 32bit onto the partition then the boot entry will automaticly be created, but I'm restoring a imaged Windows 7 32bit to the second partition, so that's why I need to create the BCD entry myself...

Any help?

Hi fanix,

Easiest is to copy the entry for 64 bit and assign it to the 32 bit partition.

After restoring the 7 x86 image, boot into 7 x64.

Open an elevated cmd prompt type the following ( press enter after each command):

bcdedit /copy {current} /d "7 x86"

It will return along number in brackets in brackets {YOUR-NEW -GUID}

Use that, including brackets in these commands ( replace ?: with the drive letter of the 7 x86 partition)


bcdedit /set {YOUR-NEW -GUID} device partition=?:

bcdedit /set {YOUR-NEW -GUID} osdevice partition=?:

close cmd prompt.

You could just run startup repair instead - but where's the fun in that?

Hope it helps

note: when restoring the image - good idea not to restore the mbr with it.

I'll give it a go, that's actually what I did earlier, maybe i did something wrong, will try again. thnx
