grub2 package

installed ubuntu 12.04 unstable beta1 release but no grub at startup

Asked by jagito

Hi there :)
I just installed ubuntu 12.04 alongside with Windows. The first "symptom" was that the installation was done automatically (no chance to tell where to install grub2). After the install no grub menu appears. What can I do?

please take a look at:
http://paste.ubuntu.com/871464/
for volumes config

TIA

Javier

If you hold SHIFT at boot, do you see the Grub menu?

No way, windows boots but no GRUB MENU

Try changing the boot device to the other drive in yourBIOS.

The only alternatives to boot are from disk (SSD), CDROM or external USB drives.
There is another drive ( 8GB) RAM drive, and it's use for "express cache" only.

Any other idea ?

Thanks

Hi Andrew

I tried it before
and this happened: http://paste.ubuntu.com/871337/

I repair it using "boot-repair", because after "reinstall" grub the "rescue" GUI was there ..............

What's the option "-bind" on command mount really do ?

And in the case I reinstall it again, which volume must I point for reinstall ?

sudo mount /dev/sda5 /mnt (The volume where ubuntu is installed)
or
sudo mount /dev/sda1 /mnt (The default BOOT partition)

-------------
sudo mount –bind /dev /mnt/dev

sudo mount –bind /proc /mnt/proc
sudo mount –bind /sys /mnt/sys
sudo chroot /mnt
grub-install /dev/sda 1 or 5 ?
CTRL-D
sudo umount /mnt/dev
sudo umount /mnt/proc
sudo umount /mnt/sys
sudo umount /mnt

jagito's conmand put the bootloader on the mbr again. It then redetects OSes and configures Grub.

In future, I suggest you stick to the STABLE releases. Pre-releases are NOT for regular users whom cannot dig themselves out of holes like this one...
