 |
|
Hi,
i cannot start my windows using grub2. What am i supposed to insert into grub.cfg to get it working. It appears in the boot menu but when hitting it does not start.
Currently my grub.cfg loooks like this:
| Code: |
if [ -s $prefix/grubenv ]; then
load_env
fi
if [ "${next_entry}" ] ; then
set default="${next_entry}"
set next_entry=
save_env next_entry
set boot_once=true
else
set default="0"
fi
if [ x"${feature_menuentry_id}" = xy ]; then
menuentry_id_option="--id"
else
menuentry_id_option=""
fi
export menuentry_id_option
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 load_video {
if [ x$feature_all_video_module = xy ]; then
insmod all_video
else
insmod efi_gop
insmod efi_uga
insmod ieee1275_fb
insmod vbe
insmod vga
insmod video_bochs
insmod video_cirrus
fi
}
if [ x$feature_default_font_path = xy ] ; then
font=unicode
else
insmod part_msdos
insmod xfs
set root='hd0,msdos14'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos14 --hint-efi=hd0,msdos14 --hint-baremetal=ahci0,msdos14 f6036196-466d-4b9a-81e6-5ede215bfc51
else
search --no-floppy --fs-uuid --set=root f6036196-466d-4b9a-81e6-5ede215bfc51
fi
font="/usr/share/grub/unicode.pf2"
fi
if loadfont $font ; then
set gfxmode=auto
load_video
insmod gfxterm
set locale_dir=$prefix/locale
set lang=de_DE
insmod gettext
fi
terminal_output gfxterm
if [ x$feature_timeout_style = xy ] ; then
set timeout_style=menu
set timeout=5
# Fallback normal timeout code in case the timeout_style feature is
# unavailable.
else
set timeout=5
fi

When I run:
| Code: | | grub2-mkconfig -o /boot/grub/grub.cfg |
I end up with the following in grub.cfg for the two Windows 7 partitions I have (sda1 is the hidden factory restore partition and sda2 is the C: drive):
| Code: | ### BEGIN /etc/grub.d/30_os-prober ###
