In the boot messages, I can see that sda and sdb (my 2 hard disks) are not mounting. When Rescatux has booted, and I choose Rescue MBR, I first get a dialog with one option that is blank (a circle to select a missing option), then a choice of sda and sdb, and then get returned to the original dialog.
Another problem is when I exit to restart, the restart stalls my machine just after I press enter following removal of the CD. I need to power down the machine manually with its start button. This problem was repeated when I tried a second time.
Am using Rescatux .08 for x86. Will try 64 bit version in case that works. My pc has Intel dual-core processor. Am using Fedora 13 and (once it's booting is corrected) Ubuntu 10.4.
