What happened was that I deleted a FAT32 partition that i had to share files between Windows XP and Fedora, and created a new ext3 partition that was supposed to be my /home partition.
But I didn't really know how to assing that partition to be home, and move everything there, so I entered every application in the Gnome menu that handled partitions, looking for something to do the task.
I came across the Volume Management System (or something like that). I saw the VolGroup00 volume, and other Unassigned partition. I assumed that the unassigned partition was my new ext3 one, and I moved it to VolGroup00, not really knowing what I was doing. Apparently, nothing happened, and I shut the machine off.
But when I tried to turn it on, I just got the grub command line. I first tought that it was just a grub problem. But after a while, and asking for advise, I realized it had something to do with the stupid Volume changes that I did.
I can still boot Windows, by typing the following in the grub command line:
I have partition magic installed in my windows partition, and I used an option that allows you to boot from any other partition. I tried to boot from my Linux partition, but no I can't even star windows properly! It's a big mess... I need that info, most of all the pictures, being a photographer... This is the worst computer-related trouble I've gotten myself into in a long time.
And my computer is a laptop, so I can't really plug my hard disk into another machine (at least I don't know how).
I hope all this explanation should help other to see a solution
By the way... what's that uuid thing? And thanks for your time...
