Grub: FC5 on primary IDE

Ballistic · 03-31-2006, 05:35 PM

Having a hard time getting Grub to load Windows. It doesn't find it when I pick that option.
I can load either by changing the boot drive in BIOS, but thats just a PITA.

Here's the basics:

HD1 (IDE) = FC5 (grub here)
HD2 (SATA) = Windows (MBR here, and I'd rather not mess with that this time....

)

Code:

#boot=/dev/hda
default=0
timeout=8
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.16-1.2080_FC5)
	root (hd0,0)
title Windows
	rootnoverify (hd1,0)
	chainloader +1

When I go to LVM:
FC5 shows as /dev/hda (with it's assorted partitions)
Windows shows as /dev/sda1
/dev/sda2 is a data partition, and I'll deal with it later.
Note that sda1 and sda2 are 2 partitions off the SATA drive

I think the

Code:

rootnoverify (hd1,0)

would be fine except that for that to work, SATA drive would need to be showing as hdb, no?

I don't have anything with a SATA drive to work with here, but I think I would try configuring so the windows drive is looked for as rootnoverify (sda1,0) Especially as you indicated it is detected as such in LVM. The command has to seek something detected.

linux see's SATA's as sda, not hda, because SATA is serial/usb as linux see's is, so it will put it as sda1

ok, that makes (obvious) sense...wish that had occured to me before....

And now the lighbulb just clicked....that explains a few things...

Well, it was worth a shot...It's not liking something, though.

I get a new error when picking the windows option.

Code:

rootnoverify (sda1,0)
Error 23: could not parse number

I must be missing something stupid in grub.conf, so here's the entire file:

Code:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=8
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.16-1.2080_FC5)
	root (hd0,0)
	kernel /vmlinuz-2.6.16-1.2080_FC5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
	initrd /initrd-2.6.16-1.2080_FC5.img
#title Fedora Core (2.6.15-1.2054_FC5)
#	root (hd0,0)
#	kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
#	initrd /initrd-2.6.15-1.2054_FC5.img
title Windows
	rootnoverify (sda1,0)
	chainloader +1

And out of curiosity, I tried with "rootnoverify (sda1,0)", "rootnoverify (sda0,0)" and "rootnoverify (/dev/sda1,0)".

All give the same error. Any ideas?
