Strange Laptop Problem

Actually, I think grub2 installed to the MBR OK - the problem seems to be after displaying the boot menu from the root directory (/boot/grub/grub.cfg). So it's past the MBR and into the new system itself. I've tried chainloader from a grub legacy setup and that does exactly the same. So unless I ( or we in UF) can solve the grub2 problem within the system itself it'll mean installing grub legacy into the grub directory. I have a suggestion to try :)

Found an error in grub.cfg and corrected it but still the same result! :( The boot instruction pointed to the wrong partition.

Hmm.... had a couple of replies in Ubuntu Forums though info-only not help. Seems they've changed numbering for partitions in grub2!!

Remember numbering changed in grub2:

In legacy-grub, the following were the mappings:

/dev/sda1 - (hd0,0)
/dev/sda5 - (hd0,4)
/dev/sdb2 - (hd1,1)

However in grub2, the above translates to:

/dev/sda1 - (hd0,1)
/dev/sda5 - (hd0,5)
/dev/sdb2 - (hd1,2)

Drives still begin with 0 but partitions begin with 1.

I think this is stupid and quite ridiculous!! :( :( Consistency flies out of the window !! :( :(

So the partition pointed to was right after all!!

(Disgusted of Devon!!)

NOPE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! It's just that that bit wasn't wrong by the new inconsistent standard!

Oh I agree - you have to laugh! Or you'd probably cry :lol

Something is wrong but don't know what. Guess I'll have to see about removing all traces of grub2 from K & L and shoving grub-legacy stuff in instead.

Think I might be getting close to getting Karmic working on my laptop :) By reverting to grub-legacy. Removed grub2 elements and installed grub-legacy. Rather tedious process! Karmic still won't boot from the standard menu item but it will from recovery mode. Choose "boot normally" from the recovery menu and you get a command line. Log in and run startx and it boots up graphically as usual. Just wonder why it won't boot in GUI straight off. I've carefully studied the contents of folders and files and compared Karmic ones with Jaunty. All looks perfectly correct!!

I had an old installation of Mandrake that did that. Had to log in via a command line and run startx. Everything was fine then and it ran as normal. Just got used to booting up like that. Odd though.

I was reading it is thought around 1/5th of people trying Karmic are having problems of one kind or another. :rolleyes
I have it running fine upstairs, but I`m keeping the the Jaunty based UE2.3 on the laptop.

Like I said in the Forums, I'm treating Karmic as a Beta release. After all it is using the Beta of grub2, though they're not even calling it grub2 yet, are they! It's grub 1.97 Beta4! I'm sticking with Jaunty for my main system - the latest "stable" release!

I've been out this morning but I expect to do more testing this afternoon. So we'll have to see. May be something to do with the splash screen - you don't get that from startx.

Now have Lucid installed and working too :) :)

Just want to tidy up the boot menu now then I shall have Jaunty, Karmic and Lucid available to boot. All with separate /home partitions. I've also added a Data partition in the remaining space where I can put stuff that's common to more than one OS. And that totally fills the HD :lol No room for the "legacy OS" :lol

OK - done that :) Now have all 3 systems booting and running on the laptop :) Set the MBR to point to Jaunty's boot menu and added extra entries into that to go to the menus for Karmic and Lucid using the grub-legacy command configfile.

If later on, I find Lucid will work with grub2, I'll use chainloader instead. That's supposed to allow booting other types of boot loader (eg. Windows)
