grub error 21 - again ?

[mrmuscle]

Hi folks, i 've been waiting for feisty fawn with hope as previous version couldn't run because of my sata jmicron controller (some kernel bug). Now - it looks okay, but not quite, i can't run kubuntu at all because of grub error 21, It appears everytime, whatever if i put grub into mbr or into fd0 (floppy) or partition with linux. I've read bout error 21, but can't resolve my prob.

The disk is single Seagate 3250824A (250 GB JMicron sata II controller), divided like this:
SDA1 - 10 GB - NTFS (xp boot)
SDA2 - 12 GB EXT3
SDA 3 - 0,8 GB SWAP
SDA5-8 - NTFS


sda1 is marked with bootflag but kubuntu doesn't start even if sda2 is flagged. Installation says it is okay to put grub into mbr as windows is detected. Here is unhashed menu.lst from grub:

title		Ubuntu, kernel 2.6.20-15-generic
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.20-15-generic root=UUID=b699f2e6-b543-424f-bb62-d30a9e6e3ad0 ro quiet splash
initrd		/boot/initrd.img-2.6.20-15-generic
quiet
savedefault

initrd		/boot/initrd.img-2.6.20-15-generic

title		Ubuntu, memtest86+
root		(hd0,1)
kernel		/boot/memtest86+.bin
quiet

### END DEBIAN AUTOMAGIC KERNELS LIST

# This is a divider, added to separate the menu items below from the Debian
# ones.
title		Other operating systems:
root


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title		Microsoft Windows XP Professional
root		(hd0,0)
savedefault
chainloader	+1

Is this correct ? Please, Help me to join kubuntu society, as i don't like suse anymore

I'd replace all occurences of root=UUID=[blurb] by root=/dev/sda2 and hope for the best ...

Re: grub error 21 - again ?

Just sharing from my own bit of experience. Did a dual-boot install of 8.10 alongside WinXP/sp3 and ran into this error.

The problem wasn't Windows or anything that Windows does.

The problem wasn't with GRUB... at least not entirely.

It seems the BIOS was re-arranging my devices; without changing any connections. The first hdd was always (hd0), but the next hdd was being moved around. (sometimes hd3, sometimes hd2, sometimes hd6)

I had to change my BIOS to remove all other boot options; switched off USB, superfloppy and other media that could be mistaken for /dev/sdX. Double-checked for 'phantom' drives, usually in Standard Settings; checking that drive positions that have no drive show as: Not Installed

Your ATAPI/SATA CD-ROM should not interfere, so you can leave it in the boot order. I can't say the same for USB/external CD-ROM.

At least for now, those have to be turned off. Eventually, I might find a way to open-up my alternate boot sources. All I know is, Kubuntu AMD64 edition is now working perfectly!
