My machine was dual-booting with Windows XP and Fedora, then I tried to install Arch. While installation power went off.
After that, booting always results in the GRUB prompt. Even when I instruct my BIOS to boot from the DVD drive, it won't. So I unfortunately cannot boot into a Live CD, be it Linux, Windows or Super Grub Disk.
The solutions I found included looking with the find command from the GRUB prompt for /vmlinuz or stage1 to find the kernel and then direct GRUB to this kernel. But the find command always tells me it cannot find any of these keywords.
However, I was able to boot into Windows from the GRUB prompt following these instructions on linuxselfhelp.com ("Load another boot loader to boot unsupported operating systems").
How can I make my machine boot again as it used to? Any help appreciated. Please tell me what information you need.
