Ubuntu Dual Boot Window 7 with two separate hard disks in one machine

For years now I've been using XP along Ubuntu on two separate hard drives without any problem.

Now, installing a Win 7 machine with two separate hard drives again, I am not capable of successfully installing Ubuntu 11.04 along with it.

Here's what happens:

  1. install W7 - no problem
  2. install Ubuntu 11.04 - seemingly no problem either (via LIVE-CD)
  3. Reboot will show the GRUB menu
  4. W7 boots properly
  5. Ubuntu shows a messed up screen, Login accepted, but Ubuntu doesn't start

I repeated the procedure with Linux Mint 11 - same same :(

So I checked wit Live-CDs (Ubuntu, Linux Mint, Knoppix, Fedora). All live systems start properly, but acces to all hard drives and thumb drives is prohibited.

Is this a preview to a supposedly upcoming W8 feature preventing a dual boot machine or accessing the file system with Live CDs?

I do depend on both OS - so I'd really like to get this working.

Please: I'm not a Geek or developer, just a "power user" with good reading skills - so be kind and friendly to a normal user :D

Thank you!

Could you boot into a Live session, try to access the Ubuntu and Windows partitions, then open a terminal and run sudo blkid; mount; sudo fdisk -l; cat /var/log/kern.log, copy the output, paste it on and post the link here? – Lekensteyn Sep 29 '11 at 10:51

Well, unless you have a UEFI motherboard that is (TM) Windows8 ready you will be able to dual boot with Windows7, even the EUFI boards Windows8 ready will have an option to disable that protection option.

You can start by telling us what kind of hardware you have, how is your hard disk configuration and where your installing your systems at.
