I want to set up Ubuntu for use as my student computer in order to remove all those gaming distractions and focus on actual productive things. I am currently running:

Windows 7 Home Premium 64 Bit 8GB DDR3 Ram Asrock P67 Pro3 Motherboard Intel core i5 2500 ATI Saphire 5850 Western Digital Green 1TB HDD WD Green 500GB HDD

And I want to install Ubuntu 32 Bit(I was going to get 64 bit, but I'm now capped for 2 weeks and can't wait that long) 11.04.

So I burned the install disk, and before I restarted, I went into the Windows disk management and shrunk the 1TB HDD(I have windows 7 installed on this) by 60GB for Ubuntu, Note I didn't format that 60GB space. Then I restarted, booted from the cd, and selected install ubuntu, there was no windows 7 detected and no install along side windows 7 option. This made me go into custom to set some stuff up: I made the 60GB ext4, set it as root, and tried to install anyway. This did not work: Windows booted like normal.

When I go to reinstall ubuntu, it detects the other ubuntu install, and offers the option to install side by side or erase, but still doesn't detect windows.

I searched on the internet for a solution and it seems the most successful way is to change my partition table system from efi(which it is in... I am pretty sure, according to windows disk management) to the older type(which I have forgotten what that is exactly). I am not against doing this, but I don't want to lose any performance with windows 7 or damage my windows install.

Once again, I want to get the ubuntu installer detecting my windows install so I can dual boot.

how are you using EFI on windows :? ,anyway it should be MBR, so what you should do is to install the windows bootloader to the MBR instead of using EFI, that way GRUB will dtect the bootloader on the windows partition, and it's DUAL boot not duel. –  Uri Herrera May 17 '11 at 9:27
yeah, I get duel and dual mixed up often. When I go to disk management, I look at my main hard drive and it has 2 partitions, one is the main partition which says (Healthy (Boot, Page File, Crash Dump, Primary Partition). But in front of that is a 100mb partition that says Healthy (EFI System Partition). That's why I think it's an EFI partition system and not MBR, I'm going to try to install ubuntu again and set the main partition to boot, instead of the 100mb partition. –  Blue May 17 '11 at 23:23
that didn't work, windows still boots as normal, no sign of grub. –  Blue May 17 '11 at 23:42
I'm not even sure if I am using EFI on windows, I've never encountered this before so don't know what to do. But I heard that newer computers use the EFI partition table and I have a 100mb partition with EFI in it. –  Blue May 17 '11 at 23:50
