Where did Linux go!

[latcarf]

I was away for the weekend and when I cane home found a mystery...

When I went to log into my server box which is as you can guess always on the login failed. It then proceeded to reboot where it told be the boot failed please insert disk in drive A and hit any key. I tried again (and again... and again) but got the same response.

I checked during reboot and it is recognizing the hard drive and I opened the box and unplugged the hard drive and it is working.

I put the FC4 Rescue disk in and it claims there are no Linux partions on the hard drive anymore!?

My first thought is a security breech (which would not surprise me) and they had nothing better to do than clean my hard drive because they could. Is this possible?

Any other thoughts or ideas?
