I installed Ubuntu 12.10 on my computer (alongside Windows 7) from a live cd, but when I rebooted my computer after a successful installation, I get a grub> prompt. When I type boot in it, it prints 

Error 8: Kernel must be loaded before booting

So I searched and I found Loading Ubuntu From Grub, but when I type linux /vmlinuz root=/dev/sda5 I get this message 

Warning! No such command: linux

Does anybody have any idea about what I should do ?

Note that I reinstalled Ubuntu but still get the same issue, and that this is not my first time installing Ubuntu (I installed many versions a dozen times before and this is the first time I've faced this issue).

When I type : kernel /vmlinuz root=/dev/sda5 instead of : linux /vmlinuz root=/dev/sda5 I get Error 15: File not found (I also tried sda4 since find /vmlinuz is printing hd(0,4))

Have you tried booting from a livecd, chrooting into your ubuntu partition(s), and manually running '# grub-mkconfig -o /boot/grub/grub.cfg'?
