 Posted: Thu May 31, 2007 7:30 am Post subject: GRUB gives "read error" when booting Windows XP |
 |
|
When I'm trying to boot Windows XP, the computer stalls. It displays the grub commands for the Windows XP entry, then nothing happens.
I believe this started when I installed a new mother board. I am, however, able to mount the drive and read/write files on it from Linux. I wish I had more information to give, but that's all I got :-S If there's any information you want, let me know.
fdisk -l /dev/hda:
| Code: | # fdisk -l /dev/hda

Hey, as far as i can see you have two partitions, one for windows (hda1) and one for linux (hda2). However, your grub.conf doesn't match the partitions... :S are you really sure that this is your grub.conf your booting with? :S Please hit me if i'm wrong 
The lines for your linux kernels refer to your windows partition: hd0,0 = hda1. So I can't really believe that your a able to boot your linux system with this grub.conf :S Additionally, your windows command line refers to the first partition of your "second harddisk": hd1,0 = hdb1 (Have a look at the grub documentation: http://www.gnu.org/software/grub/manual/grub.html.gz#Naming-convention) |

hd0 and hd2 are my SATA drives. For some reason Grub is adding the IDE drive (hd1) in the middle. |

| Okay, just tell me something about your partitions. You've got to sata disks if i understood you correctly. Where have you installed windows and where your linux system? |

Linux is installed on the SATA drives.
Windows is installed on the first 10gb of the IDE drive, and there is also a ReiserFS partition used for storage on the remaining space of the 10gb drive. |

I have the same problem. Can't boot Windows XP.
fdisk -l /dev/hde (It's in swedish but I hope you get the idea.):
| Code: |
Disk /dev/hde: 82,3 GB, 82348277760 byte
16 huvuden, 63 sektorer/spår, 159560 cylindrar
Enheter = cylindrar av 1008 · 512 = 516096 byte
Enhet Start Början Slut Block Id System
/dev/hde1 * 1 38761 19535071+ 7 HPFS/NTFS
Partition 1 slutar inte på cylindergräns.
/dev/hde2 38761 158547 60372204 83 Linux
Partition 2 slutar inte på cylindergräns.
/dev/hde3 158547 159551 506047+ 82 Linux växling / Solaris
Partition 3 slutar inte på cylindergräns.

fdisk -l /dev/sda:
| Code: | Disk /dev/sda: 320,0 GB, 320072933376 byte
255 huvuden, 63 sektorer/spår, 38913 cylindrar

Windows is in the hde1 partition, as you probably guessed. I'm using a controller card, hence hde. Linux is in the sda1 partition.
Now to the weird part - menu.lst:
| Code: | default 0
timeout 15
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo Linux (2.6.20-gentoo-r4 2) (hd0,0)
root (hd0,0)
kernel /boot/kernel-genkernel-x86-2.6.20-gentoo-r4 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda1 vga=794
initrd /boot/initramfs-genkernel-x86-2.6.20-gentoo-r4
title Windows
rootnoverify (hd2,0)
makeactive
chainloader +1 |
Root for Linux is hd0?! According to grub hd0 is hde i.e. the hdd with Windows. Somehow it still works. 
I have another ide drive (hdf, also on the controller card) which is hd1, according to grub.
I haven't used Gentoo for that long so please be gentle.  |

Ok, some of this has been solved. I've changed the order of the harddrives in device.map to match the order in bios and ran grub-install. Now the bootsplash image works, which it didn't before. In other words, the menu.lst issue is no longer.
Windows still refuses to start though... |

Usually windows won't start, if it's not in the first harddrive. I have linux in (hd0,0) and windows in (hd1,0). To remedy the situation i have this in menu.lst: | Code: | title Windows 2000
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
makeactive

For b00zy: Windows is not linux, if you changed your motherboard, you might have to reinstall windows to get it working. |

I got the same advice in an other forum. It did the trick.
Thanks! |
