 |
|
Problem to start gentoo using Grub after reboot system(after installation of gento from stage 3). Computer is turning on about 3 minutes(black screen with smal line), than shows
Booting "Windows XP"
rootnoverify (sd0,0)
Error 23: Error while parsing number
press any key to continue....
then I push any key and shows graphical screen(but blurred - maybe some problem with graphic card?) and in that screen I can choose only Windows XP(WHEN I CHOOSE IT SHOWS THE SAME LIKE ABOVE)
I didn´t use genkernel, I used manual configuration, I have disk partitioned: sda1=winxp, sda2=some partition belonging to winxp, sda3=SWAP, sda4=linux boot/200MB/, sda5=NTFS partition, sda6=Linux root
both linux partitions I think are logical, windows partitions are primary, I have SATA disk(i could use only /dev/sda, not /dev/hda during installation
My Grub configuration was:
default 0
timeout 30
splashimage=(sd0,4) boot/grub/splash.xpm.gz
title=Gentoo Linux
root (sd0,0)
kernel /boot/kernelx root=dev/sda5
title=Windows XP
rootnoverify (sd0,0)
makeactive
chainloader +1
My first installation of gentoo and no idea what to do now, is any way to reconfigure grub or what is the problem???? |

"sd" does not mean anything to GRUB. All harddrives are called "hd", and it does not matter what type of interface is used (IDE, SCSI, USB, etc.).

This means the splashimage line is pointing to the wrong place. It is OK to delete the splashimage line, then you will have a plain (but not blurred) GRUB menu.

/dev/sda2 is probably the extended partition that contains sda5 and sda6.

Try this, and see if it works better.

timeout 30
root (hd0,3)
splashimage /grub/splash.xpm.gz
title Gentoo Linux
kernel /kernelx root=/dev/sda6
title Windows XP

You can boot from any Linux live cd (not necessarily gentoo, an ubuntu cd will work just as fine), then mount your /boot partition anywhere and edit the grub.conf file to suit your needs. Reboot and voilà. Also, remember that if you can get GRUB to show you the menu (i.e. just removing the splashimage line) you can live-edit it at boot time (though not save the changes). This is specially useful when changing your kernel configurations (uvesafb on amd64, anyone?  ).
