How can i enter into my bios after my notebook was infected with a dozen virus. i tried to reformat it but i can't even enter into my bios to switch my booting sequence. i tried installing a new version of windows but it keeps on corrupting the new system. my only option was to reformat my hard drive, but i can't use my bootable cd. is there anyone who can help me with this? a help is greatly appreciated. My notebook is Dell inspiron 5100. And oh, is there anyway i can reset my bios?
