The problem comes from the initrd line:
menuentry "linux (on /dev/sda11)" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos11)'
search --no-floppy --fs-uuid --set f4deab0a-b37c-426f-bb35-f997fd2c9940
linux /boot/vmlinuz BOOT_IMAGE=linux
root=UUID=f4deab0a-b37c-426f-bb35-f997fd2c9940
resume=UUID=23a9b6ac-b275-4066-8223-b0ad9e0051ea
initrd (hd0,10)/boot/initrd.img
}
It should be either "initrd /boot/initrd.img" or "initrd
(hd0,11)/boot/initrd.img".
