*long story for a bit*
Ok, well a while ago i turn on my computer and it said, hey man, your video card is bad. So i replaced it with an old one i had laying around and poped it in there. It stopped the error but it wouldn't let me go into windows. I would say safe mode, but it would just go into a strange restarting loop. So i thought, i'd reinstall linux so i can back up all my data again...

well, im trying to install ubuntu and i get this strange error

Kernel panic - not syncing: no init found. Try passing init= option to kernel

What does that mean? I think there is something wrong with my old linux partition, but i have no means to fix it without a os on my computer

if its just about os required for backing up data use ubuntu(or anyother) live cd. You will have full control of your system.
Best of Luck

The live cd gives me the same error

Have you tried a different live cd, like Knoppix?

any linux distro that i have give me that error, such has knoppix, damn small linux, suse, mandrake, fedora, slackware, debian all of em'

I have no idea was going on!

Hmmm, odd. It could possibly be some form of hardware failure. If Windows and numerous Linux distros aren't running, I would tend to look at the hardware as the source of the problem. What kind of computer is it? If it is something like HP or Dell, remove Linux completely from your hard drive and send it in for warranty repairs. (The reason for removing Linux is that a lot of companies are very strict about NOT installing alternative operating systems.

Anyways, something to think about. Or, as a last resort, you could try a BSD based live cd like FreeSBIE, it might give u even more info.

well, its a custom made computer, my cuz. works for the geek squad at best buy and i even gave it to him to check out. Windows installer doesnt even work and he ran mobo test, hd ram all of that good stuff and it turn out fine. I have a feeling that it may be my mobo still because for some reason the audio port on it doesnt work correctly all the time, its a abit nf7-s2, not version 2, number 2

You said all this happened after you changed your video card. I would double check that the video card is fully inserted and working. Maybe you have disturbed then RAM chips in their sockets. It may even be another card in the PCI bus that has been bumped or slightly dislodged. Give all your cards and connectors a firm push to make sure they are all properly seated.
