Grub Rescue Desktop PC completely broken

This is not a Dual OS, I only have a Linux Feren OS installed. I was supposed to install Windows 7 onto it. It says I need to create a partition for Win 7 Installation. Next I hop into Command prompt and create 2 partitions. I accidentally set it to occupy the whole HDD and I deleted it. I think that might be the problem. I've restarted the PC and now I'm here at Grub Rescue. Also there is no CD/DVD drive, only USB ports. I've tried the ls command, it only shows up one HDD with one partition and it's unknown filesystem. Also tried set prefix, boot, root no help. Also insmod normal doesn't work because it is an unknown filesystem. If I can somehow boot the PC up using an USB stick, I already formatted my stick to an **ext2 filesystem** and it recognizes it. Only problem I have is that there are no files on that stick. I wonder how to copy files into an **ext2 filesystem** USB stick. I can't get past Grub Rescue, and can't enter BIOS or anything other.
