I have the problem of having the unknown filesystem: rescue grub screen come up.

I recently deleted the partition of my hard drive that had Ubuntu Studio on it in an effort to clear up more space on my computer. I also have Windows 7 installed on the computer. Also I cannot access the BIOS and there is no splash screen option for me to boot from CD. Please help.

You have to use a Windows Recovery CD/Rescue CD to fix the Windows boot problem.

You should absolutely be able to enter BIOS or choose boot order with a keyboard shortcut -- look up your system manual. Worst case, if you unplug the hard drive and boot with a CD in, the computer will probably show you the CD's splash screen. Then you can reconnect the hard drive and boot the CD.
