[ubuntu] Dual boot machine GRUB not installed

view full story
linux-howto

http://ubuntuforums.org – I have a PC with Windows 7 and recently tried installing Ubuntu 12.04. I unallocated enough free space on my hard drive and told the ubuntu installer to use said space. Everything went fine untill instalation completed, at which point a message appeared saying GRUB hadnt been installed. I've been booting with the help of supergrub disk ever since, and I know both operatig systems are in functioning state. How do I fix this? can I install GRUB or do I have to reinstall both OSs? thanks in advance (Hardware)

Stories similar to [ubuntu] Dual boot machine GRUB not installed

Hi,

I wanted to dual boot Win7 and Ubuntu 12.04LTS. So, I installed Win7 first. Then I installed Ubuntu 12.04LTS, using the "side by side" option and it went through fine and I got the grub loader asking for which i wanted to boot.

Then, there was around 100gb or unallocated space which I made as a partition of windows.

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.

My machine has 2 separate physical disks, one for each OS. Windows (sda) and Ubuntu Linux (sdb). My Windows disk had "Vista Business x64" and the linux disk has Ubuntu 12.04. I recently upgraded Vista to "Win 7 Pro x64" and as expected, it screwed with the MBR and GRUB was not coming up at boot up time.

Hahhaa....welll that was easier said than done... If you are by any chance hanging around again, reed9, I got myself into worse trouble.

I just installed Ubuntu onto my hard drive from a USB drive. When I reached the partitions screen, I noticed it listed the full hard drive as "free space" even though I already had Windows 7 installed.

I knew I had about 50 GB of free space on the hard drive, so I partitioned sda1 for 35 GB and installed Ubuntu onto it, and partitioned sda2 for 4 GB of swap space.

Reinstall Grub in target system 39 weeks 2 hours ago

I'm trying to restore Grub to boot Linux Mint 13 and Windows 7. I just installed Windows 7, which rewrote the MBR, and then I was told I could simply boot Ubuntu live cd, install boot-repair, and reinstall grub over the MBR. I went through the installation, using the option to purge the old grub, but it failed, asking me to run some terminal commands to uninstall grub.

I usually Dual boot with 2 separate Hard Drive tot have a backup just in case. Well apparently a clean install of Ubuntu 12.10 just happened to hit the exact thing. It seems the Ubuntu installer picked the Window 7 Hard Drive to install Grub, but sent everything else to the assigned hard-drive.

[ubuntu] GRUB issues.... 31 weeks 4 days ago

Hey, everyone. I currently have a dual-boot setup with Windows 7 and Ubuntu 12.04

Whenever I start my computer after booting windows previously I'm presented with a different GRUB than usual. I recently downloaded and installed linux kernel 3.6.0 and made some changes to GRUB using GRUB customizer. So I have been doing some tweaking with those files.

I recently installed Crunchbang 11 in the free space of a hard disk of an Asus netbook that already had Ubuntu installed on it.

I partitioned the 2 distros separately, with only a common swap space.

At the end of the installation, Crunchbang informed me that "it seems Crunchbang is the only OS on this system", and then asked me whether I would like to install GRUB.
