Cannot update boot configuration? Solution here.

[Guest]

Tried and tried to get Vista to install with no success. So, I went to
Toshiba's site to update the BIOS for my M200. I tried to update the BIOS and
I get an error telling me I'm not an administrator (funny, I was logged in as
admin). Later, find this way to update my MBR (kind of like the old FDISK/MBR
for XP) by going to My Computer | Manage | Storage | Disk Management and
selecting an active partition... but when I go there, it tells me it cannot
connect to the service. I google for that error (figuring it is the same
problem causing all 3 issues) and find this command:

1. Run: gpupdate /force /boot
2. Reboot
3. Have fun installing Vista

Too bad MS couldn't answer this question and save everyone months of
frustration. My guess is that when I installed RC1 of vista, it made some
changes to the policy on the machine which overwrote the XP Administrator
policies with the Vista administrator SID. Uninstalling Vista RC1 using the
bootsect tool obviously would not reset computer policies, so that was just
left messed up for the RTM install.

Note to Microsoft: upgrade your install to run gpupdate /force /boot at
install (or provide the option) if the user is logged in as an administrator
but they are getting this message.

It's also possible that the security information on the /boot directory has
the admin from a vista RC install instead of your machine and the installer
cannot access the folder to update your boot config. To check, go to explorer
and find the /boot folder (make to set explorer options so you can see
hidden/system files). Right click, and go to security. Does admin have
access? If not, you will need to click the advanced butotn on the permissions
tab and add administrator as the owner. After adding admin as owner, press ok
to apply changes and close out the permissions, then go back to permissions
and give administrator full control over the dolfer.
