(Solved-by whiteghost) /boot/grub/grub.cfg file missing

san2ban · 2012-07-09 14:55:13

still, when grub loads, it shows funtoo, windows xp. But, I am unable to boot windows on second HDD, sdb

What might be the issue? Have followed instructions on wiki while installing (/mnt/funtoo/boot)
When in chroot, this is displayed, but when i boot my system, this is not shown. I am confused.
Before I do something in desperation, some inputs please

Perhaps you missed a closing bracket:

"Windows XP" {
type winxp
}

whiteghost · 2012-07-09 15:42:18

fstab

#windows
/dev/sdb1 /boot ntfs-3g

should be something like

/dev/sdb1   /mnt/windows  ntfs-3g

if you want to access window files from linux.

boot.conf

"Windows XP" {
type winxp
}

should be

"Windows XP" {
               type winxp
               params root=/dev/sdb1
}

after editing run boot-update again.

/boot/grub/grub.cfg is not missing because your system boots.

/dev/sda1 is not mounted to /boot because of noauto fstab setting. you can remove noauto or mount /dev/sda1 manually to access /boot files.

With effort of 12 days, I have XFCE4 desktop on FUNTOO. But, the boot-update, boot.conf, grub.cfg is getting on my nerves. Inconsistent behaviour in CHROOT environment, and actual.
Tempted to go back to arch. Will try once more.
You can see below, funtoo kernel not shown

set timeout=999

menuentry "Windows XP" {
  insmod part_msdos
  insmod ntfs
  set root=(hd1,1)
  search --no-floppy --fs-uuid --set 96d40c06d40be6f9
  chainloader +1
}
set default=0

Either Funtoo, or windows, never both. Else, no grub.cfg.
With due respect, regards to Daniel, I feel boot-update should be trashed, and keep with grub mkg.conf

what kernel did you build?

if /dev/sdb1 is no longer mounted to /boot why are all those windows files in /boot? how big is your boot partition...wow?

the process of installing gentoo/funtoo teaches you some things, be willing to learn.

many people use funtoo happily so no use blaming funtoo. only 12 days? took me longer to first install gentoo.

you just have to get a kernel in /boot and you will be on your way.

san2ban · 2012-07-10 03:38:33

I use Funtoo linux genkernel, as recommended in Funtoo installation guide on wiki. Literally followed wiki to the dot. Pl. look at the below, and suggest how to dual boot. I am out of my wits. I can only oot funtoo, not windows. If I actually emerge-boot-update on my HDD 9actual environ, not CHROOT), /etc/boot.conf will get screwed. grub.cfg will vanish

Observe, there is no mention of windows, genkernel. But in CHROOT environ, windows, kernel image are shown

Whiteghost, you had asked to remove noauto from fstab, and real_root =auto from /etc/boot.conf, but according to man boot.conf, this is required for genkernel, which I use.

boot {
        generate grub
        default "Funtoo Linux genkernel"
        timeout 999
}

"Funtoo Linux" {
        kernel bzImage[-v]
        # params += nomodeset
}

"Funtoo Linux genkernel" {
        kernel kernel[-v]
        initrd initramfs[-v]
        params += real_root=auto
        # params += nomodeset
}
"Windows XP" {
               type winxp
               params root=/dev/sdb1
       }

See the bloody peculiarity, after having followed the wii to the dot, and now phyisically inside my system, when i check /boot/grub/grub.cfg, it shows blank, says newfile.
But after exiting CHROOT from sysrescue CD, (again, funtoo wiki recommendation),
while GRUB 1.98 loaded, it showed both the options, Funtoo, winxp.

I feel that, in the wiki, the part where we install the boot-loader, there is some discrepancy. This is because, only wrt boot portion, my system is not behaving as it should, according to wiki.

Any input will be appreciated

As far as winxp not booting, its a common problem with your setup. Windows likes to be the first harddrive and has issues booting when it isnt. Take a look at the grub manual: http://www.gnu.org/software/grub/manual … 02fWindows

As far as your other issues, it's quite obvious that /dev/sda1 and /dev/sdb1 were mixed up at some point. Explains why you have a grub dir in your windows partition. Plus files don't just vanish and the reappear on a partition just because you chrooted. There's also a small posibility that your disks are seen in a different order when you boot the livecd which could be why it looks messed up.

san2ban · 2012-07-10 04:20:56

rh1, it appears you posted, while I was editing. Do you mean to sat, windows also is screwed/
No way to save both funtoo, windows?

san2ban · 2012-07-10 04:24:03

Entire installation done on /dev/sda1, which is a GPY disk. Using SysrescueCD, i used to select 'boot from disk A, cant it understand that /dev/sda is disk A

san2ban · 2012-07-10 05:59:29

rh1, you scared the shit out of me.
in the BIOS, I changed it to boot from second HDD, win XP booted.
Again, as I say, no grub.cfg file exists, ls -la /boot shows as posted, yet when I boot from sda1, rub load, displays both funtoo, linux.
Funtoo loads, where as windows does not. When windows is selected, a cursor blinks at left top corner o screen

Think I am on my way back to Arch Linux. OS-prober just detects windows on sdb, puts it in grub.cfg, also boots it without issue.

rh1, your comment on window files inside boot:. For dual boot, is it not needed?

whiteghost · 2012-07-10 09:00:12

real_root =auto from /etc/boot.conf, but according to man boot.conf, this is required for genkernel, which I use.

no i said to add param for /dev/sdb1 to your windows section of boot.conf

ok.. you can boot into your funtoo, right? no need to chroot

boot into funtoo

#mount       ( is /dev/sda1 mounted to boot? if so) 
#umount /boot
#ls /boot           (should be empty, if not save what you want somewhere else then)
#rm -rf /boot/*
#mount /dev/sda1 /boot
#ls /boot     (should show grub folder, lost+found, and kernels-initramfs)

if not, reinstall grub and kernel as required.

#ls /boot        (kernel and grub folder is there, good)
#boot-update      (success)
#reboot

White-ghost, just as you said, /boot was not empty. only grub folder was there. Removed it as per your advice, followed just as you have written. Now, pl. lok ar my ls -la /boot

No grub, kernel. Also, after the changesas you suggested, windows also did not boot.
You had suggested another OP exx33 that windows entry should not be in /etc/fstab. Is it so?
I have also tried removing windows entry from /etc/fstab. Still XP does not boot from my second HDD
Pl. suggest further. Should I now emergr boot-update and install grub again? (I have rebooted now, after doing what you suggested. It showed the kernel and otherthings as you wrote, after I rebooted, it is simply missing

Does this mean, /dev/sda1 is not auto-mounted during boot?
How is the choice (Funtoo, XP) displayed

san2ban · 2012-07-10 10:22:42

after mounting /dev/sda1 to /boot, grub.cfg is displayed (i.e after having logged-in to the system

whiteghost · 2012-07-10 10:27:32

i think if you run boot-update now you will be ok.

if your boot.conf is same as above you should see genkernel and winxp choices at boot.

if noauto is set in fstab for /dev/sda1 /boot it will not automatically mount. your choice.

Is it that we can access grub.cfg, only after mounting /dev/sda1 to /boot?
Bottom line is, in normal conditions, "nano /boot/grub/grub.cfg" shows as 'new file', blank.
Windows on 2nd HDD not booting.

sorry

#mount /dev/sda1 /boot
#boot-update

then post your grub.cfg here

i think the purpose of having the noauto feature for /boot is for

safety/security. once it is set up right if it is not mounted no harm can come to it.

and grub can access it without it being mounted.

Here it is

set timeout=999

menuentry "Funtoo Linux genkernel - kernel-sysrescue-std-x86_64-3.0.21-sysrescue-std302" {
  insmod part_gpt
  insmod ext2
  set root=(hd0,1)
  search --no-floppy --fs-uuid --set 7114255e-0a65-4590-bbbf-31464fcbf893
  linux /kernel-sysrescue-std-x86_64-3.0.21-sysrescue-std302 real_root=/dev/sda4
  initrd /initramfs-sysrescue-std-x86_64-3.0.21-sysrescue-std302
  set gfxpayload=keep
}

menuentry "Windows XP" {
  insmod part_msdos
  insmod ntfs
  set root=(hd1,1)
  search --no-floppy --fs-uuid --set 96d40c06d40be6f9
  chainloader +1
}
set default=0

Iss it better to leave noauto for /boot in /etc/fstab

so you should see the choices when you boot now.
