# 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 (hd0,5)

# kernel /vmlinuz-version ro root=/dev/hda7

# initrd /initrd-version.img

#boot=/dev/hda

default=1

timeout=10

splashimage=(hd0,5)/grub/splash.xpm.gz

password --md5 $1$34ddYNVG$/jyBxa/zvg08mOeCxowoA.

Just enter this command at the terminal.

 

sfdisk -d /dev/hda | sfdisk --no-reread -H255 /dev/hda

 

Had this problem a while ago when running a FC2, Win XP config. It's a GRUB problem.

Successfully wrote the new partition table

 

Re-reading the partition table ...

BLKRRPART: Device or resource busy

The command to re-read the partition table failed

Reboot your system now, before using mkfs

 

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)

to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1

(See fdisk(8).)

 

 

 

 

when i reboot my system again n try to go XP it is giving me the samething i.e.

rootnoverify(hd0,0)

chainloader+1

 

i would be happy if anyone can get me out of this.

thaks once again

This fix is for Fedora Core 2 only. It does not apply to a ReHat 9 installation. See a full explanation at this article.

 

It is also not a grub problem, but how the Fedora disk partitioner alters the geometry, an error using the 2.6 series kernel in Fedora Core 2 and the partitioning utility in Fedora. This is not the problem in RedHat.

 

qadri, this is a RedHat 9 install?

 

The unforunate thing is that sfdisk re-wrote the partition table. I have to think about this. While I do, perhaps someone may have the answer right off.

 

Do you have the Windows install cd for this system?

 

Did you make a boot floppy for RedHat during the install? If not, you have the RedHat install disks handy?

 

What system/motherboard is this? And, this is an IDE drive, not a sata drive in the system?

 

Let's try one thing first. Get into the bios and the section that has settings for the hard drive, see if detection is set to "auto" or "LBA." If set to "auto" change the setting to "LBA" and save the changes, then reboot. See if you can get into Windows and RedHat via grub.

 

If this works, great! If not set the detection to "auto" again and save the changes, then reboot.

 

Post back what you find.

Does this problem exist with RH9? Didnt know that.

When distros started to be released with the 2.6 series of kernels, and the folks used the partitioning utility to set up their Linux install partitions in Fedora Core 1 or 2, or Mandrake 10.0, there was a flurry of activity about the problem.

 

It seems to have been solved in Mandrake 10.1 and Fedora Core 3.

 

If a user used PartitionMagic, or other partitioning utility to make their ext3 or reiserfs partiton ahead of time, there was no issue with the geometry problem.

 

So, any previous distro, like RedHat 9 which used the 2.4 series kernel (pre 2.6 kernel) the geometry issue was not a problem.
