contents of /tmp directory with bootloader error showing
Description of problem:
At the end of the installation of FC16RC1 an error dialogue box popped up saying:
There was an error installing the bootloader. The system may not be bootable.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot F16 Alpha RC DVD with anaconda 16.14.2
2.select /dev/sda11 as /boot
3.select install bootloadfer on /dev/sda11
4.proceed with the install
5.at the end get error as above
cant boot system using root (hd0,10) and chainloader +1
chainload to F16 boot partition and boot F16
No other error msgs noted. Attaching everything in /tmp dir.
By creating an entry in a F15 grub.conf using old grub nomenclature, can boot F16. During other installs of F16 from desktop spins have had success with grub2-install by specifying --force. Then chainloader +1 works. However, this has proved to be dangerous as have borked a different setup using the instructions (probably wrongly) in http://fedoraproject.org/wiki/Features/Grub2.
My assumption is that currently anaconda believes /boot is on the first parition. When it isn't, as is my test case, the error occurs.
At this time it seems as though grub2 will refuse to install to any partition without --force.
What makes you think anaconda believes /boot is on the first partition? (Especially given that it was anaconda that set up /boot on sda11)

Just an assumption in trying to understand what was happening, nothing concrete.
I tried grub2-install --grub-setup=/bin/true /dev/sda11, then sda and then sda3 (actual first linux style parition that is being used to boot all distros and windows). None worked, but then I didn't use --force since I was bitten earlier by it.
Ran grub2-install --force /dev/sda11 and can now chainload to grub2 bootloader on sda11. Note that --grub-setup=/bin/true has to be omitted.
