dual boot not working?

[infamousmrsatan]

I'm having a problem getting my windows partition to boot up using grub.

the windows and linux partitions are on two seperate physical hard drives.

here's what my grub.conf file looks like:

Code: Select all

default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz

title=Gentoo Linux
root (hd0,0)
kernel (hd0,0)/kernel-2.4.20 root=/dev/hda3

title=Win2k
root (hd1,0)
chainloader +1

When I try to boot windows I get the following:

Code: Select all

  Booting 'Win2k'

root (hd1,0)
 Filesystem type unknown, partition type 0x7
chainloader +1

any ideas??

another note, the windows filesystem is ntfs ... shouldnt' matter though.

[li1_getoo]

try

Code: Select all

chainloader (hd1,0)+1

also from what i know windows always likes to be first , so u might wanna try to swap the hard drives and make windows hd0 also edit ur lilo.conf or grub.conf

[cyrillic]

To boot Windows from the second harddrive, setup your grub.conf like this.

Code: Select all

title Win2k
map (hd0) (hd1)
map (hd1) (hd0)
chainloader (hd1,0)+1

thanks! Worked like a charm

I'm having a couple of problems. First, lets deal with the windows part.

Disk Partitions
hda1 = windows c drive
hdb1 = windows drive
hdb2 = gentoo boot
hdb3 = gentoo swap
hdb4 = gentoo root

My grub.conf looks like this, and I used genkernel also.

Code: Select all

default 1 
timeout 20 
splashimage=(hd1,1)/grub/splash.xpm.gz 

title=Gentoo Linux 2.6
root (hd1,1) 
kernel /kernel-2.6.5-gentoo-r1 root=/dev/ram0 init=/linuxrc ramdisk=8192 (not really sure what this means) real_root=/dev/hdb4 vga=795
initrd /initrd-2.6.5-gentoo-r1

title=Windows XP 
root (hd0,0) 
chainloader (hd0,0)+1

I've tried to have rootnoverify (hd0,0) for the second line as well as just have chainloader +1 but like many other people, grub just seems to just keep coming back. I get the same error as the first poster

Code: Select all

  Booting 'Win2k' 

root (hd0,0) 
 Filesystem type unknown, partition type 0x7 
chainloader (hd0,0)+1 

The second problem has to deal with gentoo booting up, first grub will execute linux and it'll start to boot up.

then, i get a section that looks like this, and it repeats over and over

Code: Select all

INIT: cannot execute "/sbin/agetty"
INIT: cannot execute "/sbin/agetty"
INIT: cannot execute "/sbin/agetty"
INIT: cannot execute "/sbin/agetty"
INIT: cannot execute "/sbin/agetty"
INIT: cannot execute "/sbin/agetty"
........ you get the picture.........

INIT: Id "c1" respawning too fast: disabling for 5 minutes
INIT: Id "c2" respawning too fast: disabling for 5 minutes
INIT: Id "c3" respawning too fast: disabling for 5 minutes
INIT: Id "c4" respawning too fast: disabling for 5 minutes
INIT: cannot execute "/sbin/agetty"
INIT: Id "c5" respawning too fast: disabling for 5 minutes
INIT: cannot execute "/sbin/agetty"
INIT: cannot execute "/sbin/agetty"
INIT: Id "c6" respawning too fast: disabling for 5 minutes
INIT: no more processes left in this runlevel
_

and then the system just hangs. This is right after installation, and i think it's because at first i started to compile the kernel myself, and then i went back and chose to use genkernel (i hadn't yet instlaled the kernel, just compiled myself). if anyone has any ideas, please let me know and thanks for your time =)

I'll also fost my fstab just incase there's a problem in there that's causing everything

Code: Select all

/dev/hdb2                  /boot               ext2   defaults,user    1 2
/dev/hdb3                  none                swap  sw                  0 0
/dev/hdb4                  /                     ext3   noatime,user    0 1

/dev/hde1                 /mnt/windowse  auto  noatime,user    0 0

none                        /proc/bus/usb    usbfs defaults           0 0
none                       /proc                  proc  defaults           0 0
none                        /dev/shm          tmpfs defaults           0 0

once agains, thanks for your help and time

The code posted above solved my problem.

Code: Select all

title Win2k
map (hd0) (hd1)
map (hd1) (hd0)
chainloader (hd1,0)+1

I have two SCSI drives, one (sda) with several Linux partitions and the other(sdb) with Windows 2000.
I could not get Windows to work until I implemented the mapping

Thanks

This thread helpt me out with my grub config, I was stuck having problems with booting to windows on my seperate sata harddrive. I think I narrowed down the problem to have my grub to include makeactive like this

Code: Select all

title windows xp
map (hd0) (hd1)
map (hd1) (hd0)
makeactive
chainloader (hd1,0)+1

As soon as I took out the makeactive it worked fine. Does anyone have an explaination as to why it worked?

Anyone with further questions on this subject would really benefit on reading Darth Daver's explanation on how to dual boot using two physically seperate hard drives. The stuff above using MAP is part of his howto. The location of the how to is: http://forums.gentoo.org/viewtopic.php?t=18319.
