Cannot boot into Ubuntu after installing Ubuntu 12.04 (with Windows 7 on another partition)

http://askubuntu.com – I just installed Ubuntu on my desktop which had Windows 7 installed on it. When I restart the machine after completing the installation, It directly loads windows, I don't see the grub menu. I tried using boot-repair using the LiveCD (both recommended fixes AND fixing the MBR), it did not help. What am I missing? I have done this at least 5 other times, on different machines, and have never faced this issue before. (HowTos)

Dual Boot - No GRUB 32 weeks 1 day ago

I have Windows 7 installed in a primary partition and wanted to install Ubuntu 12.10 in a new partition.

Hi there.

Before installing Ubuntu 11.10, I had 2 partitions in Windows, the second of which I split into 2, the second of which was used for the Ubuntu installation.

However once the Ubuntu installation completed, I could no longer boot into Windows 7, every time I chose the option, the computer would restart and bring me back to the Grub menu.

I recently installed Windows 8 onto a partition that had previously housed XP, and burned a 64-bit version of secure remix and ran boot-repair. I can now see and boot into my Ubuntu desktop, but the Windows 8 installation does not even appear on the grub menu.

I have Windows 7 on my machine and then installed Ubuntu 12.04 using a live CD. I can see both Windows 7 and Ubuntu in the grub menu, but when I select Windows 7 it shows a black screen for about 2 seconds and the returns to the Grub menu.

[Windows] EFI and Win7+Ubuntu 34 weeks 5 days ago

I've done something stupid.

When I first installed Ubuntu, things went mostly fine, the machine had Windows 7 installed already and I wanted to add Ubuntu. EFI made a bit of a mess of things, long story short I booted into a live session and used boot-repair to fix GRUB for me.

This made GRUB list 4 Windows boot alternatives and the usual two Ubuntu options.

Then I did something stupid.

I have a second machine where Ubuntu 12.04 LTS and Debian Squeeze are installed on the same HD and when I boot, I have this grub menu where I can choose which partition I will used. It works perfectly!

I formerly had windows 7 without ubuntu. Now I upgraded it to windows 8..then I installed ubuntu 12.10 with live disk.

After installing it runs ok and I see a dual boot option in grub menu. Now sometimes I log in to windows 8 for some tasks.

Original title: How can i solve (un)booting windows 7 on the same partition with grub?

I've been researching for 2/3 days about this problem and I have came up empty.

Basically, partition 1 is Windows 7 and partition 2 is Ubuntu 12.04. I told Ubuntu to install into partition 2 and to install grub on partition 1 and that works fine. But the problem now is that I can't boot to Windows 7.

How to Repair Grub 24 weeks 2 days ago
