Sorry for bad language, I'm writing from the fridge =)
I was trying to install Debian squeeze on my machine above lenny(on its partitions). I also had Windows7 on my pc. Installation wasn't successful and I made a mistake that killed Windows disk C partition =[
I tried to reinstall Windows but cd with installer wasn't found by pc, but not linux installer cd. After the long time trying to set up something I had grub in my MBR and couldn't boot from anywhere (cd, hdd, usb). And as a final thing I have a trouble: PC power on -> loading BIOS(it's all right) -> black screen with «_» blinking in left up corner.
I can't boot from anywhere and I don't know what to do. Help me please! Thanks.
