Windows 7: W7 resets bootable flag on HDD

19 Nov 2011   #11

Ultimate x64

I'm trying to persuade the MBR (that is from Windows) to always boot sda1 where is GRUB that gives me a choice of OS's. I can do this easily via fdisk from a live CD or via diskpart, however when I boot Windows again, it always resets the bootable flag to sda2, so I cannot boot to GRUB and have to use fdisk/diskpart again.

Anyway, after setting sda1 as active when I run Startup Repair, it fails: "Startup Repair cannot repair this computer automatically". bcdedit fails with the same message as above.

Right, it cannot. But GRUB can call another boot loader via chainloader.

OMG, I'm an idiot. I was booting W7 with this command:
rootnoverify (hd0, 1)
chainloader +1
...that (obviously) made hd0,1, i.e. /dev/sda2, i.e. C: active on every boot. Removing this line solved the problem.

I apologize to everyone for bothering you with such a stupidity, that even couldn't be solved from Windows. Thank you for your patience!
