I can't access Ubuntu 12.10

Question

I installed Ubuntu 12.10 but I can't reach it. The boot page doesn't appear and I can't choose which OS I want to use. It goes directly to Windows 8.

Answer 1

Probably is the windows bootloader installed, you have to replace that one with grub, you can do this with Resc-A-Tux

This is a live cd with a primary goal: Restoring grub/installing grub. It's a nice program which I used after windows just removed my grub without asking, and it worked like a charm.

When you boot it up, a popup pops up. In this popup you can select install/repair grub. Select this, it will ask some stuff, but if you click ok, it will install grub as it is always installed as default.

A small tip: Always install Windows first, since Windows just throws away grub without asking.

Rescatux features:

Fixes GRUB and GRUB2

Regenerates Debian/Ubuntu grub menues

Check and fix filesystems

Fixes Windows MBR

Blank Windows passwords

Boot Info Script

Change Gnu/Linux password

Regenerate sudoers file

Extra tools:

Synaptic

Gparted 0.7

Answer 2

I had exactly the same problem. The solution, which worked for me, is to install a program called 'Boor Repair' using your Ubuntu browser. For Instructions on how to get this free program and what to do when you've done so, see here. Good luck!

Answer 3

I also experienced this and I can confirm this worked for me and other computers

sudo gedit /etc/default/grub

then find the line #GRUB_GFXMODE delete the number sign (uncomment) and replace the resoltion with 1024x768 save it

then run sudo update-grub

so sorry I misread your question you cannot boot into ubuntu my mistake
