I have a Acer Aspire 5750G. I installed Ubuntu 12.04 - 64 bit as a dual boot onto my C: Drive using wubi (or whatever its called) but I couldn't load windows after it and formatted my laptop (later finding out that I could have just rearranged by MBR). I am now trying to install it to a partition (U: drive) and when I try to install Ubuntu it glitches out and says unable to download/load some file. I have tried downloading whole ISO and burning containing file to disk along with trying just the iso and using wubi and no matter what I do it won't install and I always get the same error. I am unable to boot using a disk (not sure if its just a issue with my laptop or because its a rental from Radio Rentals) but I have tried many other work arounds

You are unable to boot using a disk? A Compact one or ...? – Hilmi Erdem KEREN Jul 10 '12 at 13:35
i cant install using a CD, or using wubi, when i go to select boot device and select DVD drive it skips it and just loads windows so i have to use wubi to install which doesnt work either – Brodie Bryant Jul 10 '12 at 13:53
I have heard that you have to install Windows first when you do dual instillations? – jacinta Jul 10 '12 at 13:56
I don't know if you checked your CD's checksum, MD5 but, may be a corrupted CD? "It skips" doesn't seemed a bug or Error to me. Check your download and CD/DVD please. And sure, you are not forced to WUBI. Follow my answer please. – Hilmi Erdem KEREN Jul 10 '12 at 13:58
i have managed to get it to work once but says is unable to run C:\Windows\system32>bcdedit /set {cf09be72-552c-11e0-9f2d-cc1ee84230bf} device partition=U: – Brodie Bryant Jul 10 '12 at 14:00

Create your own Virtual Machine, and try to install it using your downloaded image, CD again. might help. If you can't install using VM, you have a bad download (and/or CD). If you can, mind using it or forcing WUBI to install again.

im currently installing on vmware now :) it iv had it running once on my laptop but couldnt boot into windows so did a factory restore and now it wont reinstall, 30 mins remaining on the vmware install – Brodie Bryant Jul 10 '12 at 14:10

I found a solution here.

In the BIOS, replace graphic mode by 'integrated' (by default it's 'switcable). This works well on my machine.
