grub problem in F14

[Joachim Backes]

Hi,

I have 3 SATA disks on my box with 3 installed systems:

/dev/sda with windows7 on /dev/sda1, /dev/sdb for data and /dev/sdc for
2 Fedora systems: /dev/sdb5 with F13 and /dev/sdb7 with a fresh
installed F14/Rc1.

My F14 runs properly. Now I wanted to install under F14 grub again on
the boot disk /dev/sda (grub-install /dev/sda), and it seemed to be OK.
But if trying to boot, Win7 no more could be booted (no boot record found).

Booting back to F13 and reinstalling grub with the identical
grub-install command and booting again: Win7 could be booted.

/boot/grub/grub.conf are identical in F13 and F14.

Now I found out, that the usage of *--force-lba* in grub-install
produced a clean bootloader on /dev/sda, so I could boot Win7 with a
boot loader generated in F14.

What I not understand is the fact, that under F13 --force-lba is *not
needed*, but seems to be needed on F14.

My board: ASRock ConRoe1333-DVI/H

Kind regards
