 Posted: Sat Apr 27, 2013 11:07 pm Post subject: [SOLVED] Grub is installed but doesn't start |
 |
|
I'm trying to end my installation with grub and a reboot, but I get unexpected issues.
this is my partition table (I also have other hard drives but they have no bootable partitions)
| Code: |
Disk /dev/sda: 20.5 GB, 20547841536 bytes, 40132503 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: 0xe01ae01a
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 67583 32768 83 Linux
/dev/sda2 67584 4261887 2097152 82 Linux swap / Solaris
/dev/sda3 4261888 40132502 17935307+ 83 Linux
|
I emerged and installed grub (grub-install --no-floppy /dev/sda) and it seems to be installed in /dev/sda1 (/boot)
| Code: |
drwxr-xr-x 2 root root 1024 Apr 28 01:25 .

I wrote grub.conf as follows (and also tried with only "root=/dev/sda3", with only "real_root=/dev/sda3" and with both "real_root=/dev/sda3" and "root=/dev/ram0" as the default config file was written)
| Code: |
default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo Linux 3.7.10
root (hd0,0)
kernel /boot/kernel-genkernel-x86-3.7.10-gentoo root=/dev/sda3 real_root=/dev/sda3
initrd /boot/initramfs-genkernel-x86-3.7.10-gentoo
|
No way... I tried to install it manually in /dev/sda like in the x86 handbook (I tried also /dev/sda1 "setup (hd0,0)"):
| Code: |
# grub --no-floppy
grub > root (hd0,0)
grub > setup (hd0)
grub > quit
|
But every time I reboot nothing happens... Grub doesn't start and I have to reboot into the installation cd and chroot again again and again...
I think now it could be harmful that Grub could be installed twice, into MBR and into /dev/sda1,... how do I uninstall it if I like to try lilo i.e.?
What am I missing?
-----------------------------------------------
Solved:
The wrong boot sequence was NET --> CD --> IDE1
Now is NET --> CD --> IDE0

leonixyz,
Grub is in several parts, some of it will be in your /dev/sda1 (/boot) some in /dev/sda MBR. You need all the parts.
As grub does not start, either your hard drives have changed BIOS names between the install and normal boot. (Some BIOSes do that), or your BIOS is not booting from your Gentoo install.
