My OS Mint-9 (Isadora) does not start any more. This morning it was ok and then a message came-up saying "Firefox has crashed" and nothing was working after that. I tried to restart system but all I got is - black screen with Mint logo on it and 5-white dots that normally would change colors, but this time this dots were just sitting there doing nothing, also on my Logitech keyboard 2 lights begun to flash on the upper right side - that normally never flashed before this problem, one of the lights is Caps Lock and the other is Scroll Lock, they flash in unison and at steady rate. Tried few shut-down's and few re-start's but to no avail.
Mint-9 shares HD with Ubuntu-10.04. They share 320 GB drive 50/50. Ubuntu-10.04 works fine but Mint-9 for some reason developed some sort of problem. At start-up Ubuntu-10.04 is the first to start unless I scroll down and select Mint-9.
I don't know much about computers and will need detailed guidance as to what to do to fix this problem. Don't know any shop that works with this type of OS in San Francisco, California.
