Hello, i have dedicated server with no OS from hp with iLO console, so all i have to set via java console. I did wrong debian install, installation is not complete and i would like to do again. I can not get to bios, because in this console is no way to use bios F keys. So is here any way to remove/back server to factory settings and get clean dedicated server as before? In iLO panel is not possible to do this. Or maybe use iso again and try rescue mode? But was created virtual drivers etc. and would like to remove all.
Can you not boot the server from Debian installation media? There you can create new disk partitions and start a fresh install. For other questions, consult the iLO and other documentation
never used hp's iLO but if it's anything like dells idrac, you should be able to upload the install media iso from your local pc, and then boot from that, then as @Taleman says, you should be able to remove any existing disk partitions and restart the install from new.
