Windows 7: Help needed with BOOTLDR, BCD on a multiboot machine

16 Oct 2011   #11

Windows 7 Home Premium N 64bit

Thanks for all the help !

This thread is nearing closure.

The main breakthrough came when I discovered EasyBCD. Great tool with good online documentation.
Using this tools and the inputs from this thread, I fumbled my way to a solution.

Main steps :
* Using EasyBCD, set correct MBR to [disk 2]
* Using EasyBCD, set correct BCD and bootmgr to partition [win sys] of [disk 2]
--> now booting Windows straigh from [win sys] without any side loop through [win install]

* observed that the BCD on [win install] partition was automatically backed up at earlier, happier times. Reinstating this backup to be the acting BCD for this partition made the deal : now if I boot from this partition, via grub,I effectively boot to the install and repair process.

While I was there, I used this procedure (option 2) to build a bootable install USB stick.

Finally, back under Linux, a sleak mkisofs enabled be to back up the [win install] partition as a sanctuarized iso image.

Additional resources I found useful :

Boot Configuration Data in Windows Vista
Windows Vista startup process - Wikipedia, the free encyclopedia

Still not completely sure I understand everything I did, but well ... it works as intended and I certainly learned a thing or two in the process.
