I have Windows 7 and had a dual boot with Wubi. I recently installed BackTrack 5 on my hard drive and in doing so messed up my Ubuntu 11.10, so I downloaded the new Ubuntu 12.04 and burned the image to a CD. When I restart to the CD/DVD drive the GRUB loader comes up and not the Ubuntu install.

I have checked the contents of the image and all the files seem to be in order. When I try to run from command in BT5r2 its unable to find autorun. So I burned another disc and have the same problem. It's unable to locate autorun and it wont autorun from restart and my BIOS is correct. I even tried from USB and got 'unable to find OS'.

I don't have a Windows 7 install disc. I am looking to do a full install of Ubuntu 12.04. Any help would be appreciated.

Did you try making a bootable usb with the 12.04 iso? – harisibrahimkv May 2 '12 at 5:53
yes and i get something along the lines of no operating system detected – cityboy609 May 2 '12 at 6:03
i might have made the bootable usb wrong though, i sent the downloaded iso to the usb and set BIOS as boot from usb , i might need further instruction on making the usb properly bootable – cityboy609 May 2 '12 at 6:07
Do you have another Ubuntu available near you? Then you can use its "Startup Disk creator" to create a bootable pen drive. – harisibrahimkv May 2 '12 at 6:07
sorry , i do not my original ubuntu was a dual boot with wubi and upon my partitioning for BT5r2 i was unable to load my ubuntu – cityboy609 May 2 '12 at 6:13

I solved the problem. It seems the Roxio image burner for Windows doesn't set the disc up right, so I used isoburner and the CD loads perfectly. Ubuntu 12.04 then installed perfectly from the newly burned disc. Thanks for your advice.
