Hi, I wonder if anybody could please advice me on a booting issue. I have double hard disk computer, which I was using with either Ubuntu or Windows depending on the need of the moment. I have been using the F10 option at start-up to select the Windows HD when needed. After upgrading to the latest version of Ubuntu, I cannot boot in Windows any more. While I was upgrading, "Grub" software opened options, and I most likely selected the wrong ones. Now when the computer boots, only does it in Ubuntu, even if I select Windows option. Even selecting the HD of Windows with the F10 option, still doesn't boot on Windows, it just get stopped on a black screen. For the grub version : ada(a)ada-desktop:~$ dpkg -l grub\* Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ un grub <none> (no description available) ii grub-common 1.98-1ubuntu5 GRand Unified Bootloader, version 2 (common un grub-coreboot <none> (no description available) un grub-doc <none> (no description available) un grub-efi <none> (no description available) un grub-efi-amd64 <none> (no description available) un grub-efi-ia32 <none> (no description available) un grub-emu <none> (no description available) un grub-ieee1275 <none> (no description available) un grub-legacy <none> (no description available) un grub-legacy-do <none> (no description available) un grub-linuxbios <none> (no description available) ii grub-pc 1.98-1ubuntu5 GRand Unified Bootloader, version 2 (PC/BIOS un grub2 <none> (no description available) Here is a copy of the grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then load_env fi set default="0" if [ ${prev_saved_entry} ]; then set saved_entry=${prev_saved_entry} save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z ${boot_once} ]; then saved_entry=${chosen} save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n ${have_grubenv} ]; then if [ -z ${boot_once} ]; then save_env recordfail; fi; fi } insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 8af1e583-20e8-459f-94b6-2e1c12a7e952 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=640x480 insmod gfxterm insmod vbe if terminal_output gfxterm ; then true ; else # For backward compatibility with versions of terminal.mod that don't # understand terminal_output terminal gfxterm fi fi insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 8af1e583-20e8-459f-94b6-2e1c12a7e952 set locale_dir=($root)/boot/grub/locale set lang=en insmod gettext if [ ${recordfail} = 1 ]; then set timeout=-1 else set timeout=10 fi ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### set menu_color_normal=white/black set menu_color_highlight=black/light-gray ### END /etc/grub.d/05_debian_theme ### ### BEGIN /etc/grub.d/10_linux ### menuentry 'Ubuntu, with Linux 2.6.32-21-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 8af1e583-20e8-459f-94b6-2e1c12a7e952 linux /boot/vmlinuz-2.6.32-21-generic root=UUID=8af1e583-20e8-459f-94b6-2e1c12a7e952 ro quiet splash initrd /boot/initrd.img-2.6.32-21-generic } menuentry 'Ubuntu, with Linux 2.6.32-21-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 8af1e583-20e8-459f-94b6-2e1c12a7e952 echo 'Loading Linux 2.6.32-21-generic ...' linux /boot/vmlinuz-2.6.32-21-generic root=UUID=8af1e583-20e8-459f-94b6-2e1c12a7e952 ro single echo 'Loading initial ramdisk ...' initrd /boot/initrd.img-2.6.32-21-generic } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/20_memtest86+ ### menuentry "Memory test (memtest86+)" { insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 8af1e583-20e8-459f-94b6-2e1c12a7e952 linux16 /boot/memtest86+.bin } menuentry "Memory test (memtest86+, serial console 115200)" { insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 8af1e583-20e8-459f-94b6-2e1c12a7e952 linux16 /boot/memtest86+.bin console=ttyS0,115200n8 } ### END /etc/grub.d/20_memtest86+ ### ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Microsoft Windows XP Home Edition (on /dev/sdb1)" { insmod ntfs set root='(/dev/sdb,1)' search --no-floppy --fs-uuid --set e29010fc9010d8bd drivemap -s (hd0) ${root} chainloader +1 } ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### # This file provides an easy way to add custom menu entries.
