I've got a frustrating problem. I have a Dell SC440 machine that's worked perfectly for me for a couple years. Up until a few months ago I dual-booted Windows 7 and Ubuntu 9.04 with Grub, with absolutely no problems. I upgraded to Ubuntu 9.10 and the new kernel, and the new kernel refused to boot - if I selected it in Grub it would lock up. I could, however, still boot into the old linux kernel.
I killed and recreated the partition, and I've tried to install Ubuntu 9.10 from scratch. It gets past the initial boot screen, but locks up immediately after. The exact same thing happens for Fedora 12, OpenSolaris 2009.06, and Vector Linux. I can't install in text-safe mode (or its various other names) either. LiveCD doesn't work.
The funny thing is that Ubuntu 9.04 still installs and loads just fine, and also runs the live CD. GParted boot-CD works fine. These two seem to be the only bootable CDs that work for me.
Any thoughts?
Thanks
