Hi, I come across syntax error when using grub2-mkconfig -o /boot/grub2/grub.cfg in Fedora 17, pls help!!!
*The following is the whole process:* 1. I installed Win7 first, and then Ubuntu 12.04 LTS, at this time grub can correctly find win7 and Ubuntu and both can boot. Finally I installed Fedora 17. Now Grub can now detect Win7 and Fedora and both can boot too. But Ubuntu is not in the boot list. I want to show all of the three systems in the list. 2. I try to boot the Ubuntu with commands in GRUB2 boot prompts following the steps in section *Encountering the dreaded GRUB 2 boot prompt** *at https://fedoraproject.org/wiki/GRUB_2. I used the following commands according to my situation, and all commands succeed and Ubuntu boot normally. (hd0,7) is the root partition for Ubuntu and (hd0,6) is the /boot partition. set root=(hd0,7) linux (hd0,6)/vmlinuz-3.2.0-26-generic-pae root=/dev/sda7 ro quiet splash $vt_handoff initrd (hd0,6)/initrd.img-3.2.0-26-generic-pae 3. I want to modify the *grub.cfg* to show all the three systems in the boot list. 1). I boot into Fedora17, I add one file named 15_Ubuntu in the directory /etc/grub.d. Below is its content. *All the commands are same as what I used in grub2 boot prompt above.* #!/bin/sh -e exec tail -n +3 $0 # This file provides an easy way to add custom menu entries. Simply type the # menu entries you want to add after this comment. Be careful not to change # the 'exec tail' line above. echo "Adding Ubuntu to GRUB 2" cat << EOF menuentry "Ubuntu, with Linux 3.2.0-26-generic-pae" { set root=(hd0,7) linux (hd0,6)/vmlinuz-3.2.0-26-generic-pae root=/dev/sda7 ro quiet splash $vt_handoff initrd (hd0,6)/initrd.img-3.2.0-26-generic-pae } EOF 2). Then I use the grub2-mkconfig command to re-create the grub.cfg file: grub2-mkconfig -o /boot/grub2/grub.cfg The output says there are errors: Generating grub.cfg ... Found linux image: /boot/vmlinuz-3.4.4-5.fc17.i686 Found initrd image: /boot/initramfs-3.4.4-5.fc17.i686.img Found linux image: /boot/vmlinuz-3.3.4-5.fc17.i686 Found initrd image: /boot/initramfs-3.3.4-5.fc17.i686.img No volume groups found Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sda2 * error: syntax error. error: Incorrect command. error: syntax error. Syntax error at line 175 Syntax errors are detected in generated GRUB config file. Ensure that there are no errors in /etc/default/grub and /etc/grub.d/* files or please file a bug report with /boot/grub2/grub.cfg.new file attached.done* *These commands have been verified in GRUB 2 boot prompts. I do not know which line is line 175 and where is the specific error.* 3). If I remove the newly added file 15_Ubuntu from directory /etc/grub.d and grub2-mkconfig again, the output has no error messages. *FYI, the partition information is as follows (there are two swaps now, just ignore it. I will update later):* [root@HanMing grub.d]# fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x9157ea21 Device Boot Start End Blocks Id System /dev/sda1 * 2048 3074047 1536000 7 HPFS/NTFS/exFAT /dev/sda2 3074048 100397055 48661504 7 HPFS/NTFS/exFAT /dev/sda3 100399102 596467711 248034305 f W95 Ext'd (LBA) Partition 3 does not start on physical sector boundary. /dev/sda4 596467712 625139711 14336000 7 HPFS/NTFS/exFAT /dev/sda5 100399104 414971903 157286400 7 HPFS/NTFS/exFAT /dev/sda6 414973952 415948799 487424 83 Linux /dev/sda7 415950848 425713663 4881408 83 Linux /dev/sda8 425715712 433526783 3905536 82 Linux swap / Solaris /dev/sda9 433528832 496889855 31680512 83 Linux /dev/sda10 496891904 497915903 512000 83 Linux /dev/sda11 497917952 578033663 40057856 83 Linux /dev/sda12 578035712 588275711 5120000 83 Linux /dev/sda13 588277760 596467711 4094976 82 Linux swap / Solaris Disk /dev/sdb: 2001 MB, 2001731584 bytes 26 heads, 56 sectors/track, 2685 cylinders, total 3909632 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc3072e18
