Just use a FAT32-formatted USB-'Mass-Storrage-Device'/Stick/HDD copy the unpacked Nooby-Package (FMCB-Installer and INSTALL-Folder) to the root of this 'stick' and rename the ELF to 'RESCUE.ELF' (without quotes).
Insert your stick to the PS2, power it on and the FMCB-Installer should start up.
Edit: Please do not start multiple threads for your issue.
I deleted your other thread, since it was in the wrong section.
Btw.: No need to 'waste' a DVD-/+R.
