Unable to boot - /bin/sh: can't access tty: job control turned off

Hi, Am really hoping someone can help me here. I know this is a vague error and there is not a simple step by step solution, but I am pretty stuck and need to be able to boot. Basically, I have a dual boot machine running Studio 64 and Ubuntu. I upgraded Ubuntu to 9.04 using a live USB (I have no CD drive on this machine). Ubuntu boots fine (but is pretty much only used for web/word processing/basic requirements) but every time I try and boot Studio 64 I get this error: /bin/sh: can't access tty: job control turned off I know this is described elsewhere http://www.64studio.com/node/729 but I cannot find a reason for this happening since the re-install. Before I get the error, I get a few messages along the lines of: mount: Mounting /sys on /root/sys failed: No such file or directory mount: Mounting /proc on /root/proc failed: No such file or directory and then: Target filesystem doesn't have /sbin/init Does anyone have any suggestions to fix this? Or on what has happened? Do I need to re-install Studio 64? If you need any further info, just ask. Thanks.
