What's the difference between booting from the MBR and root / drive?
Which to choose during installation? Default is MBR.

Both MBR& the root partition would be the safer choice; doesn't hurt
& would be safer when windows changes the MBR.

e.g. I had installed opensuse 11.2 on the weekend it became available
& winxp was running in dual boot mode. Recently "upgraded" to win7
which was the required "clean install" from 32-bit winxp to 64-bit win7.

The MBR got changed by the win7 install; still was able to get to linux
as I had installed grub to boot from both the MBR& root /.

"Minor problem" is that the Bootpart used in winxp to have multiple
boots doesn't work on win7;& win7 changed the booting process so that
it doesn't use the boot.ini directly but it is "modified"& appended
to whatever the win7 bootmgr uses for booting (bootldr). Will be
looking for a substitute for win7 multiple os booting so that grub
can boot from the MBR again.

hmmmm, haven't checked the windows option on grub to boot win7 as yet;
more things to do to figure out some things about win7.

I had to eliminate dual booting on my lap top because Win7 and Ubuntu
would not coexist without destroying each other's booting. I could load
win7 and it worked fine. Then install Ubuntu and it works fine with grub
booting but win7 would no longer boot all the way. It keep rebooting
after the pretty pulsating flower. Then I would fix win 7 and then
Ubuntu would not boot even with super grub. Fix Ubuntu and win7 broke
again. I gave up and have only win7 (as microshaft wants) and run Ubuntu
and Opensuse as virtual machines on win7 host.

I don't have any problem with the win7 doing the MBR as I had installed
grub on both the the MBR & root as my usual procedure; I also had used
bootpart to install/change the winxp boot.ini to be able to boot linux
from windows in case I selected windows from grub when I meant linux.

Found that beginning with vista & win7, microsoft changed how windows
boot from the mbr as windows no longer use "ntldr", but its own
boot manager. Hard way to config/edit the boot loader is to use BCD
or easier is to use the free "easybcd". Another method for checking
or some editing is to use the msconfig that came with the system; then
linux should be booting from its root partition.

I am leaving my setup the way it is with win7 as the default os as
kde killed my sound; the soundcard works in the yast testing of the
ht omega card in console mode. If the sound in opensuse starts to
work again, not holding my breath, I may change the default os in the
win7 boot manager.
