Hi everybody
I want to modify Bootmgr windows 8 to reference BC1, BC2, ... (hex edit value BCD in Bootmgr windows 8 to BC1, BC2...) For bootmgr windows 7, I can do this by small software called Zbootmgr.exe. But Zbootmgr.exe can't modify Bootmgr windows 8.
Please help me and excuse me for my poor English.

I'm sure you can do this with BCDEDIT from an Elevated Command prompt, but I find it much easier to use EasyBCD.

I think you want to alter bootmgr to point at a different bcd store .

Some kind of hex editing.

Is that intended to boot different images from a wim ?

Maybe ask joakim at sanbarrow.

That's true.
Grub4dos >> Bootmgr1 >> BC1 >> Win8x86\Boot.wim >> Win8x86\install.wim to setup windows 8 32bit
and
Grub4dos >> Bootmgr2 >> BC2 >> Win8x64\Boot.wim >> Win8x64\install.wim to setup windows 8 64bit

You can help me hexedit Bootmgr windows 8?
