Hello
Last year I tried Ubuntu on a live CD on my mother's laptop that had Windows Vista. She didn't like it, so we didn't install it. For some time we had been thinking about upgrading to Windows 7, and yesterday we did. So her laptop has Windows 7 now, but when we turn it on, it asks if we want to boot Windows 7 or Ubuntu. I don't even know where Ubuntu might be, I thought the live CD thing would necessarily be temporary.
And let me just add... I don't know if this is related, maybe I will open another topic for this... Her hard drive is partitioned into C: and D:. The OS is on C:. C: has a total size of 39GB. Yesterday I noticed there are 25GB being used with I don't know what! I mean, there's Windows and other stuff... And those things take maybe 10GB at most, but C: only has some 8GB free. The other 20 something GB are completely unaccounted for. I'm just putting this here because I thought maybe there is some sort of hidden Ubuntu partition...
