 Posted: Tue Sep 09, 2003 4:58 pm Post subject: Dual Boot Windows 98 and Gentoo 1.4 GRUB Problem |
 |
|
I am running a PII 300MHz with 64MB RAM and a 40GB disk. I have already installed Windows 98 and over the past two days, Gentoo has been compiling from stage 1. All was well, until a reboot when I got:
| Quote: | | GRUB: Hard disk error |
Nothing more happens. I can't boot anything. And I have absolutely no idea why. So some more information.
My partition layout is as follows:
| Code: | /dev/hda1 9GB Windows partition fat32 (flagged bootable)
/dev/hda2 extended partition
/dev/hda5 /boot ext2 30Mb (flagged bootable)
/dev/hda6 / reiserfs 9Gb
/dev/hda7 /home reiserfs 10Gb
/dev/hda8 swap 192Mb
/dev/hda9 /usr reiserfs 12Gb |
After emerging grub (which compiled with no problems) I did the install:
| Code: | grub> root (hd0,4)
grub> setup (hd0) |
This was fine.
My grub.conf looks like this, and I have linked it to menu.lst:
| Code: | timeout=30
default=0
fallback=1
title=Gentoo 1.4
root (hd0,4)
kernel (hd0,4)/boot/bzImage root=/dev/hda6
title=Windows 98
rootnoverify (hd0,0)
chainloader (hd0,0) +1 |
This seems to be a problem with GRUB. If I boot GRUB from a floppy disk and type in the commands to boot Gentoo, it works fine. I haven't tried booting Windows from the GRUB floppy. I have however, used a Win98 boot floppy and re-written the mbr, like so:
On reboot, Windows loads. What is also strange, what before I decided to re-install my system to re-partition and change Linux distro, I had a dual boot Win98/Redhat 7.2 system and used GRUB as my bootloader. I never had any problems.
Does anyone have any ideas as to why GRUB gives me a hard disk error? Any help would be appreciated.
Cheers,

IMHO your comp (bios) doesnt support booting after N cylinders
I would try using small booting partitions for both windows and gentoo for dual booting

missed that post in documentation and tricks 
thanks for pointing it out. i do get the feeling that my BIOS can't handle the booting after n cylinders (it also has a problem booting from cds despite there being an option in the BIOS). i'll try putting a small boot partition at the beginning of the disk, but afaik windows 98 must reside in the first primary partition of the disk (unlike win2k and win xp). |
