My aoa150 contracted a virus that disabled my antivirus. Went to do a sys recovery, no problem, right? At end of System Recovery, got an error: Cannot format the object drive. press OK to return. <ok> Restore failed. click OK to restart the computer. <ok> black screen with a blinking cursor in the upper left corner. I have an external which I thought to restore from, only it tells me "NTLDR is missing", press ctrl+alt+del to restart. Any ideas?
