package grub-pc 1.97~beta4-1ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Binary package hint: grub2

Failed to merge grub.cfg after running update manager and getting the latest kernal following a clean install of 9.10-AMD64 that followed a Windows 7(32-bit) upgrade on dual boot Toshiba L305D-S5959 Laptop. Of course the clean install was done in response to losing grub with the Windows 7 32-bit upgrade. This was an easy fix on another system that had Ubuntu 9.04 as the only previous system when installing Win 7 RC x64 to create another dual-booting system . Now I have no idea where this stands yet. But looking at grub.cfg l don't really see the problem, but I'm not bug hunting there tonight. I'll copy on the bottom of this post. Haven't re-booted yet, but I'm betting it's okay.

This may just be a little bit of scary error trapping by somebody, and not truly a bothersome bug.

Admittedly I'm trying to break things in Win 7 and Ubuntu both. FYI, I have an MS TechNet Subscription for research purposes. But the Win7 32 upgrade was a Toshiba customized for their laptops as I purchased a new laptop just last August. All I can say is grub-pc/grub2 certainly has obfuscated the fix compared to the straightforward method before the release of 9.10.

Here's grub.cfg, unedited.
