Problem after GRUB reinstall

**Shamanix** · 09-27-2005

My linux partition is on SDB6, My windows partition is on SDA1. I recently installed windows xp again, so i went into rescue mode from the kubuntu dvd. i selected SDB6 as root partition and after that i wrote "grub-install /dev/sda1"(where mbr is).

grub was successfully reinstalled, but every time i select to boot windows xp it goes straight back to the grub menu, so only linux is bootable... where does the problem lie? tried MANY times :P

Here's a part of my menu.ist file (/boot/grub):

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1

root (hd0,0)

Did you try "grub-install /dev/sda" instead of "grub-install /dev/sda1"?

/sda1 is the number of the 1st partition on the 1st hard drive.
/sda is the first hard drive.

You should aso check out Nerderellos grub tutorial, which can be found in the General Tutorials section.

tried both, with /sda1 and /sda. doing "fixmbr" after grub install on sda1 worked, but "fixmgr" after grub install sda idn't work (grub still starts)...

I am a little conused here.
When you run "fixmbr" that will get rid of whatever is on the MBR and replace it with a Windows bootloader.

Are you trying to create a dual-boot system or ....

no, but i tried to "fixmgr" before i reinstalled grub...

btw, should i have a "grub.conf"-file in /boot/grub?

You should have a menu.lst file or a grub.conf file in /boot/grub. As long as you have 1, it doesn't matter which.

And you are trying to run "fixmbr", not "fixmgr", right?

yes, "mbr". even installed windows again last night, then installed grub, still the same...

Could it be that i have serial-ata or linux on one hd and windows on another?

try putting :-

Code:

title Microsoft Windoze XP
rootnoverify &#40;hd0,0&#41;
makeactive
chainloader +1

The rootnoverify statement says "this is where the operating system (OS) is, but don't verify that you can find one now, as it's a non-grub aware OS". The makeactive does just that, and then the chainloader statement says that the OS needs to be loaded in this way and that the first bit of the OS lives at block 1 on the hard disk that you already pointed to (with the rootnoverify).

good luck

didn't work

maybe there's a problem with the HD, should i delete "everything" and make new partitions?
