Ubuntu 12.0.4 amd64 boot screen won't appear

Asked by Majid Navabi on 2012-12-27

Hi. I have Win 7 on my computer, then installed Ubuntu 12.04 from dvd. During installation I selected manual partitioning, then created a primary partition beside my Win 7 partition and installed Ubuntu on it. Everything went on normally with no error and Ubuntu installed successfully. The problem is that when installation completed and I rebooted, there is no screen which I can select Ubuntu, only my Win 7 starts automatically, as if I have never installed Ubuntu. Please help me with this. Thanks a lot.

Could you please tell me how I should do this? When I start my PC, it goes straight to Windows. There is no option to select Ubuntu. Do you mean I should boot my PC with Ubuntu disk and type this in terminal?

Hold SHIFT at boot, does Grub show up?

Grub won't show up. It's like Grub has not been installed at all.


Assuming you did not use grub, that will work.

well, I should certainly add this info, I have 2 HDD on my system, when I booted from hdd1 Ubuntu boot appeared, while I have installed Ubuntu on my hdd0, I assume grub has been installed on hhd1 instead of hdd0. anyway my problem has been solved. Thanks a lot "andrew-woodhead".
