I have a weird one for you. I have a Dell Dimension 2400 & when I boot it, I get an error message that says "Diskette Drive Failure Drive 0"...press F1 to retry. I press F1 & the same thing will happen. I went into the BIOS & reset all the setting to factory reset & it did not help so I then wanted to set it back to factory defaults. So I booted it up & pressed F11 to get into the restore partition. Instead of booting into the restore partition I booted fine.....it goes straight into the operation system & works great if I press F11. If not I get the error "Diskette Drive Failure Drive 0"....what has happened?
