Will not boot Windows 7 after 9.1 upgrade to 10.04

[cyninger]

I've been reading a bit and have managed to glean enough information to download and run the Boot Info Script (http://sourceforge.net/projects/bootinfoscript/) (output below), but I've been smacked by the same issue that has been hampering a few users here.

I've selected the wrong options when asked about the updated GRUB versions and now my machine will not boot into Windows. Ubuntu Netbook Remix 10.04 is good.

I can boot into recovery mode and have already tried to repair GRUB... no luck.

Here is the script output:

Thanks to all who can lend a hand here.

For the sake of anyone else who might stumble on this thread, I've also updated a desktop installation on another laptop - kept the existing GRUB configuration and everything works fine.

[oldfred]

Everyone is misreading the instructions on installing grub. There is a difference between MBR and PBR. Windows has essential boot files in its PBR and grub has overwritten it.

http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:Boot_Sector

Grub 2 is installed in the boot sector of sda1
You only want grub in sda not sda1.

[cyninger]

Understood.

I'll take my Windows installation DVD and attempt to fix the installation as I have read others have done with success. I'll post back here when complete, may take a bit as this is a machine I use occasionally.

Thank you for the reply.

[oldfred]

If using the windows disk to repair it is the fixboot command that will replace the boot sector and should be all that is required. A few have additional issues.

[trixtah]

I wouldn't say anything about the users "misreading" the grub update instructions - they were incredibly unhelpful and misleading. I strongly suggest that someone patch them to actually give decent advice to us dual-booters.

If I can be a systems administrator for over a dozen years and still "misread" the grub help during the setup - I wish I could have exited the install at that point! - that "help" isn't that great.

Let's hope that running the usual fixboot for Windows doesn't mean I b0rk all the OSes I have.
