grub2 upgrade - problems

[klaus2008]

I think that you should compare the old configuration file menu.lst and the new one grub.cfg concerning the boot parameters for Knoppix.

You can find many web pages with tutorials about the configuration of GRUB 2. I think that "GRUB 2 bootloader - Full tutorial" could be a good place to start.

If you still have problems then I would suggest that you show us the content of the configuration file grub.cfg and give a detailed description of where your Windows partition resides (drive number and partition number).

I hope this helps.

Sorry Klaus,

I updated this post about 8 hours ago - clearly it didn't take (grrrr), here's what should have uploaded...

Fix for missing Windows link in Grub2 menu:

The steps for this require root access, so use Root Shell or sudo.

Edit file:

/etc/grub.d/40_custom

Add this section to the end of the file:

menuentry "Windows 7" {
set root=(hd0,1)
chainloader +1
}

(Note this worked for me as Windows boots from first partition (sda0,0) - partition numbering changes in Grub2, now starts at 1 not 0)

At command prompt run:

update-grub

That's it, this curred my missing Windows option in grub2 menu.
Missing wireless is proving harder to track down, and is still causing a problem if anyone can help?

Within the link Klaus told you, you can find this hint:

30_os-prober is the script that will scan the hard disks for other operating systems and add them to the boot menu.

Perhaps it isn't yet installed. Install it and try update-grub once more. There is no need to edit '/etc/grub.d/40_custom' manually.
